181-624: The Chester Canal was an English canal linking the south Cheshire town of Nantwich with the River Dee at Chester . It was intended to link Chester to Middlewich , with a branch to Nantwich, but the Trent and Mersey Canal were unco-operative about a junction at Middlewich, and so the route to Nantwich was opened in 1779. There were also difficulties negotiating with the River Dee Company , and with no possibility of through traffic,

362-547: A caisson of water in which boats float while being moved between two levels; and inclined planes where a caisson is hauled up a steep railway. To cross a stream, road or valley (where the delay caused by a flight of locks at either side would be unacceptable) the valley can be spanned by a navigable aqueduct – a famous example in Wales is the Pontcysyllte Aqueduct (now a UNESCO World Heritage Site ) across

543-510: A drainage divide atop a ridge , generally requiring an external water source above the highest elevation . The best-known example of such a canal is the Panama Canal . Many canals have been built at elevations, above valleys and other waterways. Canals with sources of water at a higher level can deliver water to a destination such as a city where water is needed. The Roman Empire 's aqueducts were such water supply canals. The term

724-473: A scheduled ancient monument , and is unique in England. Shortly afterwards is Beeston Stone Lock, also a listed structure, but dating from the construction of the canal and using conventional materials. The next lock is Tilston Lock, situated about 1 mile (1.6 km) to the north of Bunbury . The railway crosses to the north side of the canal near Bunbury Staircase Locks, a staircase of two locks which share

905-534: A scheduled monument in 1994, and work eventually started on its refurbishment in 1999. It reopened in 2002, and is once more hydraulically powered. The use of modern hydraulic fluids is expected to prevent the problem of corrosion suffered when it was originally built. The navigation is managed by the Canal and River Trust (CRT) as far as Winsford Bridge. Beyond this are Winsford Bottom Flash and Winsford Top Flash. Both are shallow lakes , resulting from subsidence in

1086-415: A "cistern", or depressed area just downstream from the fall, to "cushion" the water by providing a deep pool for its kinetic energy to be diffused in. Vertical falls work for drops of up to 1.5 m in height, and for discharge of up to 15 cubic meters per second. The transport capacity of pack animals and carts is limited. A mule can carry an eighth-ton [250 pounds (113 kg)] maximum load over

1267-508: A bid to ensure that both remained profitable despite competition from the railways. This came soon, for the Grand Junction Railway from Warrington to Birmingham had been authorised before the canal opened, and was carrying goods by January 1838. Tolls on the canals were considerably lower than had been envisaged when the route was promoted. Experiments with steam tugs to haul trains of narrow boats were carried out in 1842, and

1448-644: A branch to Nantwich . Although the Corporation of Chester subscribed £100 towards the scheme, and the societies and clubs of Chester put up another £2,000, there was little enthusiasm for it. Neither the Weaver Navigation nor the Trent and Mersey were supportive, as both might have lost some trade if the canal were built, and when the Duke of Bridgewater was approached for support, he replied that provided

1629-485: A broad canal, designed with locks which were 80 feet (24 m) by 14 feet 9 inches (4.50 m) suitable for broad-beam barges. Most of the Trent and Mersey Canal north of the proposed junction was suitable for barges which were 14 feet (4.3 m) wide, but the final three locks in Middlewich, and all of those south of the junction, are only suitable for 7-foot (2.1 m) narrow-beam barges. The project

1810-496: A canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as slack water levels , often just called levels . A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin , and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley . A canal can cut across

1991-498: A canal to run "from the River Dee, within the liberties of the city of Chester, to or near Middlewich and Nantwich". The act allowed the company to raise £42,000 by issuing £100 shares, and an additional £20,000 if necessary. Of this, only £28,000 had been subscribed at the time of the act, but construction began near Chester, with Samual Weston acting as engineer and John Lawton working as his assistant. Weston had previously worked as

2172-459: A central arch, and there are flood relief arches on each side of the channel. The two waterways run roughly parallel for several miles. They diverge near Winsford , the current head of navigation, and at Northwich the river turns to flow north-west across north Cheshire . Below Winsford, the course of the river has been altered several times, by the construction of cuts and locks, to enable small ships to trade on it. The river formerly joined

2353-471: A chemical industry developed in the area around Northwich, which became the major source of income for the Navigation. The locks on the river are paired, with two lock chambers side by side, and in most cases the larger lock also has intermediate gates, so that ships of varying length can be accommodated, without undue waste of water. The maximum size of the locks is 196 by 35 feet (60 by 11 m) above

2534-413: A combination of the three, depending on available water and available path: Smaller transportation canals can carry barges or narrowboats , while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal ), or from one sea or ocean to another (e.g., Caledonian Canal , Panama Canal ). At their simplest, canals consist of a trench filled with water. Depending on

2715-475: A connection to the growing canal network, there was little future for the river or the Port of Chester. The idea had first been raised three years earlier, when merchants suggested a line from the Trent and Mersey to near Runcorn . There were no objections from the Corporation of Liverpool, but the canal company was non-committal. By 1770, the plans were a little clearer, with a main line from Chester to Middlewich and

2896-484: A curving route anti-clockwise across west Cheshire , northern England . Improvements to the river to make it navigable were authorised in 1720 and the work, which included eleven locks , was completed in 1732. An unusual clause in the enabling Act of Parliament stipulated that profits should be given to the County of Cheshire for the improvement of roads and bridges, but the navigation was not initially profitable, and it

3077-455: A different arch of the structure. The weir at Frodsham was built in 1785, although it has been altered subsequently. The main curved section is 49 yards (45 m) wide, and there are two 16-foot (5 m) sluices at the southern end. The adjacent lock, which was designed by Robert Pownall and George Leigh in 1781, was modified in 1830 and later, but most traffic was using the Weston cut by

3258-413: A draught of 4.5 feet (1.4 m), but the actual depth exceeded 6 feet (1.8 m). Debts continued to increase, as the commissioners borrowed more money to fund the improvements. The new weir and lock at Pickerings failed in 1761 and both had to be rebuilt. Work had started on Witton Brook in 1756, but the plans were revised in 1764 to increase the navigable depth to 4.5 feet (1.4 m), and this work

3439-400: A hydraulic system. A descending tank caused hydraulic fluid to enter the pistons which raised the other tank. The design was a success, but the fluid became contaminated, resulting in corrosion of the pistons. The lift was replaced by a new design, where each tank was attached to its own counterbalance weight by wire ropes and pulleys, with small electric motors to overcome friction. The new lift

3620-549: A journey measured in days and weeks, though much more for shorter distances and periods with appropriate rest. Besides, carts need roads. Transport over water is much more efficient and cost-effective for large cargoes. The oldest known canals were irrigation canals, built in Mesopotamia c.  4000 BC , in what is now Iraq . The Indus Valley civilization of ancient India ( c.  3000 BC ) had sophisticated irrigation and storage systems developed, including

3801-551: A line from near Whitchurch to Hurleston Junction , just to the north of Nantwich. It opened on 25 March 1805, and water supply was enhanced by the construction of a navigable feeder through Llangollen to Horseshoe Falls on the River Dee at Llantisilio. In 1804, the Ellesmere company offered to buy out the Chester Canal for 1,000 of their shares, and to take over debts up to £4,000. The Chester Canal held out for more, and

3982-558: A line from the River Mersey at Netherpool (later renamed Ellesmere Port ) to the River Dee near Chester, to give access to the Chester Canal, and branches to Shrewsbury , Ruabon , Llangollen , Bersham , Llanymynech and maybe Whitchurch and Wem . Although William Jessop estimated that the cost would be £196,898, it was the time of the Canal Mania , and 1,234 subscribers offered £967,700. Applications were scaled down and

4163-474: A lock built on the Barnton cut between 1832 and 1835. The Pelton turbines which control the gates were built to Stoney's patent, and carry plates which indicate that they were manufactured by Hanna, Donald & Wilson of Paisley . Acton swing bridge is a symmetrical bowstring girder swing bridge, which was built in situ between 1931 and 1933, on an island in the centre of the river. It was first swung across

4344-618: A new lock connected the cut to a basin, and tide gates connect the basin to the Mersey. This cut was called the Weston Canal and was completed in 1810. A fourth act of Parliament was obtained on 2 May 1825, which altered some of the details of the previous act of Parliament, and the River Weaver Navigation Act 1829 ( 10 Geo. 4 . c. lxx) of 22 May 1829 noted that the Weston Canal had been completed. It stated that

4525-581: A rather low gradient for its time. The canal is still in use after renovation. In the Middle Ages , water transport was several times cheaper and faster than transport overland. Overland transport by animal drawn conveyances was used around settled areas, but unimproved roads required pack animal trains, usually of mules to carry any degree of mass, and while a mule could carry an eighth ton, it also needed teamsters to tend it and one man could only tend perhaps five mules, meaning overland bulk transport

4706-576: A report in 1844 indicated that they were then used extensively. By the following year, however, the Ellesmere and Chester company were thinking about converting the canal to a railway, and argued that steam tugs were no cheaper than locomotive haulage on a railway. A merger with the Birmingham and Liverpool Junction Canal was discussed in 1844, and was authorised by the Ellesmere and Chester Canal Company Act 1845 ( 8 & 9 Vict. c. ii) on 8 May 1845,

4887-414: A sectional pontoon, which is immersed in the river and carries about 80 per cent of the weight of the bridge. Dutton Horse Bridge , which carries the towpath over the weir stream at Dutton, is one of the earliest surviving laminated timber structures. Dutton railway viaduct , which was built by Joseph Locke and George Stephenson for the Grand Junction Railway, is grade II* listed, and a civic celebration

5068-415: A surveyor, and had been involved in excavating canals as a contractor, but had no experience of managing a major engineering project. The Mayor of Chester cut the first sod at the end of April. There were concerns that while the canal was being constructed past Northgate Gardens, prisoners from Northgate Prison might escape, and the company had to give a bond against this possibility. The canal was conceived as

5249-428: A swing bridge crosses the lock. The gates are opened by a Pelton water turbine mechanism, and other features include a water levelling mechanism and a system for removing rubbish from behind the gates using jets of water which are controlled mechanically. The lock keeper's cottage is also grade II listed. It was built in the 1850s, but was moved northwards by 20 yards (18 m) during the 1890 reconstruction. Below

5430-459: A uniform altitude. Other, generally later, canals took more direct routes requiring the use of various methods to deal with the change in level. Canals have various features to tackle the problem of water supply. In cases, like the Suez Canal, the canal is open to the sea. Where the canal is not at sea level, a number of approaches have been adopted. Taking water from existing rivers or springs

5611-573: A watermill was a feature from the 13th century; 100m further north, an early 19th-century stone bridge, with a single span, crosses the river. Continuing northwards, it passes under the Middlewich Branch of the Shropshire Union Canal before the village of Church Minshull . The aqueduct carrying the canal was designed by Thomas Telford and was built of brick with stone bands between 1827 and 1833. The river flows through

5792-422: Is a channel that cuts across a drainage divide , making a navigable channel connecting two different drainage basins . Both navigations and canals use engineered structures to improve navigation: Since they cut across drainage divides, canals are more difficult to construct and often need additional improvements, like viaducts and aqueducts to bridge waters over streams and roads, and ways to keep water in

5973-459: Is larger, with eight arches each carrying a sluice gate. Where the weir stream rejoins the main channel, the towpath is carried over it on Horse Bridge , which was designed by J. A. Saner, the Navigation's engineer, in 1915, and erected in 1916. It is one of the earliest surviving laminated timber structures, and consists of two arches, both over 100 feet (30 m) long. Below the locks, Joseph Locke and George Stephenson built another viaduct for

6154-480: Is opposite Wharton's Lock, which is followed by the village of Tiverton on the north bank. Immediately after a bridge carrying the A49 road over the canal is the first of the two Beeston locks. The first is called Beeston Iron Lock, and was built from cast iron plates in 1828 by Telford. Cast iron was used because of problems with running sand under the original stone locks. It is both a grade II* listed structure and

6335-626: Is possible for pleasure craft to reach the Weaver from the Ship Canal, it is a commercial waterway, and most leisure users are dissuaded from doing so by the amount of paperwork and the requirements of the operating company. Situated just below Northwich, the Anderton Boat Lift is now the normal route for leisure boats to reach the river. Following its closure in 1983, a trust was created to campaign for its restoration. The lift became

6516-701: Is presumed, introduced in Italy by Bertola da Novate in the 16th century. This allowed wider gates and also removed the height restriction of guillotine locks . To break out of the limitations caused by river valleys, the first summit level canals were developed with the Grand Canal of China in 581–617 AD whilst in Europe the first, also using single locks, was the Stecknitz Canal in Germany in 1398. In

6697-599: Is rarely less than 30 metres (98 ft) wide. In the 5th century BC, Achaemenid king Xerxes I of Persia ordered the construction of the Xerxes Canal through the base of Mount Athos peninsula, Chalkidiki , northern Greece. It was constructed as part of his preparations for the Second Persian invasion of Greece , a part of the Greco-Persian Wars . It is one of the few monuments left by

6878-456: Is rated good or fail. The water quality of the Weaver was as follows in 2019. Reasons for not achieving good quality include agricultural runoff and the discharge of treated effluent from sewage treatment works along the length of the river. Chemical status was rated good until 2016, but is now rated fail, largely due to the presence of polybrominated diphenyl ethers , which are used as flame retardants in many products, mercury compounds, and

7059-418: Is steeper than the desired canal gradient. They are constructed so the falling water's kinetic energy is dissipated in order to prevent it from scouring the bed and sides of the canal. A canal fall is constructed by cut and fill . It may be combined with a regulator, bridge, or other structure to save costs. There are various types of canal falls, based on their shape. One type is the ogee fall, where

7240-452: Is the pound lock , which consists of a chamber within which the water level can be raised or lowered connecting either two pieces of canal at a different level or the canal with a river or the sea. When there is a hill to be climbed, flights of many locks in short succession may be used. Prior to the development of the pound lock in 984 AD in China by Chhaio Wei-Yo and later in Europe in

7421-618: The Chester Canal Act 1777 ( 17 Geo. 3 . c. 67), which allowed them to raise another £25,000, by additional calls on existing shareholders, and to borrow £30,000 as a mortgage. They succeeded in raising £6,000 by making additional calls, and borrowed £4,000 from Richard Reynolds , an ironmaster from Ketley, who was responsible for several of the East Shropshire Canals, including the Wombridge Canal and

7602-658: The Elbe , Oder and Weser being linked by canals. In post-Roman Britain, the first early modern period canal built appears to have been the Exeter Canal , which was surveyed in 1563, and open in 1566. The oldest canal in the European settlements of North America, technically a mill race built for industrial purposes, is Mother Brook between the Boston, Massachusetts neighbourhoods of Dedham and Hyde Park connecting

7783-437: The Ellesmere and Chester Canal in 1830, but felt that water supply would be a problem. New cuts were constructed at Barnton, Crowton and Aston Grange between 1832 and 1835, and they then planned to construct a second lock beside each of the original locks. William Cubbitt was asked for advice on whether the river could be adapted for seagoing ships, and although he said it could, he did not think it would be cost effective. Work

7964-531: The Ketley Canal . The money was used to complete the line to Nantwich, and to build a reservoir at Bunbury Heath. The work was completed in August 1779, and the company hoped to raise enough money to then build the line to Middlewich. They proposed building it with narrow locks, to reduce the cost, but the shareholders were not prepared to support them; instead they concentrated on trying to generate traffic on

8145-590: The Manchester Ship Canal was opened in 1894. The tidal section of the river below Frodsham now flowed into the ship canal, rather than the River Mersey, and the exit lock from Weston Docks also joined the canal rather than the estuary. A new ship lock was constructed at Weston Marsh, which provided a more convenient route to the ship canal than the alternative route through Weston Point docks. The Weston Canal has been little used since. Although it

8326-517: The Mersey Flats at neap tides, resulting in them having to wait for days at Frodsham. In 1796, users of the navigation suggested that it should be extended to Weston Point, where the water was deeper. The trustees wanted to pay for this extension by raising tolls, but the users objected, and it took several years to work out a deal which suited both parties. Finally, the trustees obtained a third act of Parliament on 8 August 1807, which authorised

8507-483: The Montgomeryshire Canal , which is the subject of an ongoing restoration scheme, can be accessed. Boaters can also access the River Dee at Chester, although advance notice must be given, and the river is only accessible for four hours either side of high tide. At Ellesmere Port, the canal has connected to the Manchester Ship Canal since its opening in 1894. For many leisure cruisers, the requirements of

8688-543: The Naviglio Grande built between 1127 and 1257 to connect Milan with the river Ticino . The Naviglio Grande is the most important of the lombard " navigli " and the oldest functioning canal in Europe. Later, canals were built in the Netherlands and Flanders to drain the polders and assist transportation of goods and people. Canal building was revived in this age because of commercial expansion from

8869-545: The Phoenix metropolitan area was the most complex in ancient North America. A portion of the ancient canals has been renovated for the Salt River Project and now helps to supply the city's water. The Sinhalese constructed the 87 km (54 mi) Yodha Ela in 459 A.D. as a part of their extensive irrigation network which functioned in a way of a moving reservoir due to its single banking aspect to manage

9050-528: The River Brue at Northover with Glastonbury Abbey , a distance of about 1.75 kilometres (1,900 yd). Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. More lasting and of more economic impact were canals like

9231-413: The River Mersey at Weston Marsh, but since the construction of the Manchester Ship Canal , begun in 1887, it has flowed into the canal, from where surplus water enters the Mersey by the Weaver sluices, just upstream of the junction. The tidal river section below Frodsham has been bypassed by the Weston Canal since 1810, and is no longer navigable, as Frodsham Lock is derelict. The river runs through

9412-641: The Shrewsbury Canal , with a back trade in iron ore from near Burslem ; general merchandise, which was carried between Chester and Liverpool; and general merchandise for Shropshire and North Wales. All of these were profitable. The carriage of general goods from Birmingham to Liverpool and the Chester coal trade both made a small loss. Once the canals were owned by the London and North Western Railway , restrictions were imposed on what they could carry, and

9593-489: The Shropshire Union Railways and Canal Company was formed from the Ellesmere and Chester company, which also took over a number of canals which joined theirs. Plans to convert some of the canals to railways were put on hold in the 1847, when the canal company was leased to the London and North Western Railway . Under railway control, the canals continued to operate successfully, but decline set in during

9774-614: The Songhai Empire of West Africa, several canals were constructed under Sunni Ali and Askia Muhammad I between Kabara and Timbuktu in the 15th century. These were used primarily for irrigation and transport. Sunni Ali also attempted to construct a canal from the Niger River to Walata to facilitate conquest of the city but his progress was halted when he went to war with the Mossi Kingdoms . Around 1500–1800

9955-556: The reservoirs built at Girnar in 3000 BC. This is the first time that such planned civil project had taken place in the ancient world. In Egypt , canals date back at least to the time of Pepi I Meryre (reigned 2332–2283 BC), who ordered a canal built to bypass the cataract on the Nile near Aswan . In ancient China , large canals for river transport were established as far back as the Spring and Autumn period (8th–5th centuries BC),

10136-404: The stratum the canal passes through, it may be necessary to line the cut with some form of watertight material such as clay or concrete. When this is done with clay, it is known as puddling . Canals need to be level, and while small irregularities in the lie of the land can be dealt with through cuttings and embankments, for larger deviations other approaches have been adopted. The most common

10317-471: The 12th century. River navigations were improved progressively by the use of single, or flash locks . Taking boats through these used large amounts of water leading to conflicts with watermill owners and to correct this, the pound or chamber lock first appeared, in the 10th century in China and in Europe in 1373 in Vreeswijk , Netherlands. Another important development was the mitre gate , which was, it

10498-472: The 15th century, either flash locks consisting of a single gate were used or ramps, sometimes equipped with rollers, were used to change the level. Flash locks were only practical where there was plenty of water available. Locks use a lot of water, so builders have adopted other approaches for situations where little water is available. These include boat lifts , such as the Falkirk Wheel , which use

10679-477: The 1830s were replaced by five much larger locks, and most of the bridges were replaced by swing bridges, which enabled coasters of up to 1000 tons to use the river. Construction of a connection between the river and the Trent and Mersey Canal was begun in 1871 and completed in 1875. Because of the difference in level, a vertical boat lift was designed by Edwin Clark, using counterbalanced tanks which were linked by

10860-595: The 20th century, and when many of the adjoining canals were closed in 1944, the sections which had been the Ellesmere and Chester Canal and the Birmingham and Liverpool Junction Canal, together with the Middlewich Branch, were retained. The canals were nationalised in 1948, and long-distance commercial traffic had all but ended by 1958. In 1963, the British Waterways Board was formed and the canal ceased to be operated by railway interests for

11041-455: The Anderton boat lift, and 213 by 37 feet (65 by 11 m) below it. The lock at Weston Point Docks is slightly narrower, at 213 by 36 feet (65 by 11 m). The boat lift is designed for canal craft rather than ships, and so can hold vessels up to 72 by 14 feet (21.9 by 4.3 m) with a draught of 4 feet (1.2 m). Access to the navigation was improved for traditional canal boats with

11222-487: The Cheshire salt-producing area, but was not deep enough to allow boats to reach the salt mines. It was tidal for around 7 miles (11 km) to Pickering's wharf, and salt from the mines was carried by pack horse to the wharf, where it was loaded into barges. These used the ebbing tide to carry them back down the river. By the early 17th century, coal was being transported into the area so that it could be used to evaporate

11403-409: The Chester Canal, supplemented by a steam engine at Ellesmere Port which pumped water from the Mersey. Passenger boats along the canal proved very popular, with connections from Ellesmere Port to Liverpool provided by larger boats, although passenger services from Chester to Nantwich lasted for less than a year. Commercial traffic also grew steadily, helped by the construction of new basins at Chester and

11584-427: The County of Cheshire, in line with the original act of Parliament. Further improvements to make the river suitable for coasters began in 1856, when Edward Leader Williams was appointed as engineer. He oversaw the complete reconstruction of the navigation between 1870 and 1900, a programme which was designed to ensure that the river remained attractive to carriers, and which ensured its profitability. The 12 locks of

11765-404: The Grand Junction Railway, which was completed in 1836 and is grade II* listed. It has 20 arches, and was built at a cost of £54,440 by a London civil engineering contractor called David McIntosh. A civic celebration was held on its completion, as there had been no deaths and no serious injuries to the workers during its construction. The navigation has since been re-routed, and now passes through

11946-473: The Llangollen Canal turns off at Hurleston Junction immediately rising through four locks. Soon, Nantwich Basin is reached, which was the historic terminus of the Chester Canal. Telford's original plan was to terminate the Birmingham and Liverpool Junction Canal by running it across Dorfold Park and joining the basin end-on, but the owner objected, and an embankment had to be built around the edge of

12127-463: The Middlewich Branch, bound for Manchester. The canal company carried goods in their own boats, and produced a report on the four years from August 1846 to June 1850 in 1851. This showed an income of £180,746 from tolls, and identified six main types of traffic. These included iron goods from the Wolverhampton area to Liverpool; limestone from Trevor and Crickheath to Nantwich or Wappenshall on

12308-553: The Midlands. With the prospect of being part of a link between Liverpool and the Midlands, the joint company had again pressed for the construction of the Middlewich branch, which would give them an outlet to Manchester and the Potteries industrial centre around Stoke-on-Trent. The Trent and Mersey Canal refused to sanction the idea of a canal which would effectively reduce their income until the Birmingham and Liverpool Junction Canal

12489-590: The Persian Empire in Europe . Greek engineers were also among the first to use canal locks , by which they regulated the water flow in the Ancient Suez Canal as early as the 3rd century BC. There was little experience moving bulk loads by carts, while a pack-horse would [i.e. 'could'] carry only an eighth of a ton. On a soft road a horse might be able to draw 5/8ths of a ton. But if

12670-587: The River Dee and entered the canal system at Chester. There was trade in iron from Ruabon to Chester, but the tolls were very low, as the canal route was 58 miles (93 km) long, whereas the land journey was only 20 miles (32 km). In 1838, the canals carried 60,406 tons of iron bound for Liverpool, most of it manufactured goods, of which 38,758 tons came from Staffordshire, 11,687 tons from North Wales and 9,961 tons from Shropshire. An additional 10,370 tons, most of which originated in North Wales, passed along

12851-785: The Southwest by 1300 CE. Archaeologists working at a major archaeological dig in the 1990s in the Tucson Basin, along the Santa Cruz River, identified a culture and people that may have been the ancestors of the Hohokam. This prehistoric group occupied southern Arizona as early as 2000 BCE, and in the Early Agricultural period grew corn, lived year-round in sedentary villages, and developed sophisticated irrigation canals. The large-scale Hohokam irrigation network in

13032-404: The Trent and Mersey generated significant trade for the Navigation, for in 1793 a system of chutes was constructed at Anderton, to enable salt from narrow boats on the canal to be tipped into Weaver flats moored in a dock some 50 feet (15 m) below the level of the canal. The steady increase in traffic encouraged the trustees to press on with improvements. Witton Brook was widened in 1788, and

13213-447: The Weston Canal, which provided a link to Weston Point, where boats could reach the River Mersey at most states of the tide, as the water was deeper. The navigation was completely reconstructed between 1870 and 1900, with the original locks being replaced by five much larger locks, capable of handling 1000-tonne coasters. With the opening of the Manchester Ship Canal , a new lock was constructed at Weston Marsh, which gave direct access to

13394-482: The Wirral line. The Ellesmere company responded quickly, agreeing to make changes to their act of Parliament, and the Chester company continued to supply water. On the strength of this, they were also able to raise some money to put the canal into good order and to repay some of their debts. The Ellesmere company extended their canal eastwards from Frankton to Whitchurch , and in 1802, the two companies reached agreement on

13575-607: The Witton Brook from the Weaver to Witton Bridge. Following a plea by the owner of brine workings near Middlewich, who felt they would be disadvantaged by the new navigation, the River Dane Navigation Act 1720 ( 7 Geo. 1. St. 1 . c. 17) was obtained on 7 June 1721 to authorise improvements to the River Dane, but did not result in any work being undertaken. Progress was slow, as only Richard Vernon of

13756-450: The amount of money owing to the undertakers gradually rose to a peak of £19,659 by 1740. Toll receipts improved, and by 1757, the debts had been reduced to £9,809. In September 1757, merchants from Liverpool complained about the run-down state of the navigation to Liverpool Corporation, who offered to pay for a survey. The merchants then offered to take over the navigation, but the commissioners wanted to keep control of it, and paid £17,000 to

13937-539: The bend. To the south of the canal is the old city, one of the few English cities which retains nearly all of its city walls , the cathedral much of which dates from 1092, and the King Charles' Tower, which overshadows the canal. After rising 33 feet (10 m) through the Northgate Staircase locks, which were cut out of solid rock, the canal enters a steep-sided rock cutting. After several bridges,

14118-474: The bridge swings. During the project, river access was only possible by narrow boats and other small craft. Frodsham viaduct, completed in 1850 and built in brown bricks with a cast-iron central arch, was built for the Birkenhead, Lancs & Cheshire Junction Railway by the contractor Thomas Brassey . The engineer for the project was Alexander Rendel . The Environment Agency assesses the water quality of

14299-602: The brine, and as the industry expanded, there were calls to improve the river to simplify this trade. There was opposition to the initial schemes, however, from landowners who feared flooding and from carriers who feared a loss of trade, which resulted in Bills laid before Parliament in 1711, 1715, 1718 and 1720 being defeated. In 1720 the first act of Parliament , the River Weaver Navigation Act 1720 ( 7 Geo. 1. St. 1 . c. 10) to authorise improvements to

14480-513: The canal did not physically link with the Trent and Mersey at Middlewich, he would not oppose the plans. Despite attempts at flattery, the Duke would not alter his position, and so the company promoting the bill in Parliament began with a serious disadvantage. The bill became an act of Parliament, Chester Canal Act 1772 ( 12 Geo. 3 . c. 75), on 1 April 1772, authorising the construction of

14661-492: The canal passed to the British Waterways Board on 1 January 1963, and for the first time in over 100 years, it was managed by an organisation which was not under railway control. The Transport Act 1968 classified all waterways under the jurisdiction of British Waterways into commercial, cruising and remainder waterways . All of the remaining Shropshire Union network was designated as cruising waterway, with

14842-436: The canal pressure with the influx of water. It was also designed as an elongated reservoir passing through traps creating 66 mini catchments as it flows from Kala Wewa to Thissa Wawa . The canal was not designed for the quick conveying of water from Kala Wewa to Thissa Wawa but to create a mass of water between the two reservoirs, which would in turn provided for agriculture and the use of humans and animals. They also achieved

15023-597: The canal to Egerton, the main mortgagee, but he did not respond to their offer. Angry landowners who had not been paid drained Bunbury reservoir in March 1782, but somehow the committee managed to keep the canal open, by selling boats and land. Disaster struck in November 1787, when Beeston Staircase Locks collapsed, and there was no money to fund repairs. In 1790 the plans for the Ellesmere Canal were published, and

15204-418: The canal to form a dam. They are generally placed in pre-existing grooves in the canal bank. On more modern canals, "guard locks" or gates were sometimes placed to allow a section of the canal to be quickly closed off, either for maintenance, or to prevent a major loss of water due to a canal breach. A canal fall , or canal drop, is a vertical drop in the canal bed. These are built when the natural ground slope

15385-444: The canal was uneconomic. Part of it was closed in 1787, when Beeston staircase locks collapsed, and there was no money to fund repairs. When the Ellesmere Canal was proposed in 1790, the company saw it as a ray of hope, and somehow managed to keep the struggling canal open. The Ellesmere Canal provided a link to the River Mersey at Ellesmere Port from 1797, and the fortunes of the Chester Canal began to improve. The Ellesmere Canal

15566-462: The canal. Where large amounts of goods are loaded or unloaded such as at the end of a canal, a canal basin may be built. This would normally be a section of water wider than the general canal. In some cases, the canal basins contain wharfs and cranes to assist with movement of goods. When a section of the canal needs to be sealed off so it can be drained for maintenance stop planks are frequently used. These consist of planks of wood placed across

15747-542: The canals at the present time." Despite such official attitudes, Eric Wilson, who produced the first edition of Inland Waterways of Great Britain in 1939, noted that those wishing to use the Shropshire Union for leisure cruising should apply to the Agent at Chester. He advised that application should be made well in advance, in case there were problems due to the condition of the waterway and its locks. Control of

15928-471: The canals failed to make sufficient money to cover the interest on mortgages. However, they made a substantial operating profit for some years. Around 1850, the average annual income was £104,638, which yielded a surplus of £45,885. Most of the income was from carrying, and by 1870, income had risen to £143,976, although this only yielded a surplus of £11,727. Total traffic was 855,462 tons in 1858, but this had dropped to 742,315 tons in 1868. The carrying business

16109-471: The channel on 10 August 1933. J. A. Saner was again the designer. Dutton locks are of a similar design and age to those at Saltersford, and the Pelton turbines were made by Northern Foundry Co. Ltd. of Oldham, who are described as turbine makers on the cast-iron covers. Dutton sluice, some 160 yards (150 m) to the north-east of the lock, was built in the 1870s, in a similar Baroque style to Hunt's weir, but

16290-469: The channel. There are two broad types of canal: Historically, canals were of immense importance to commerce and the development, growth and vitality of a civilization. In 1855 the Lehigh Canal carried over 1.2 million tons of anthracite coal; by the 1930s the company which built and operated it for over a century ceased operation. The few canals still in operation in our modern age are a fraction of

16471-478: The city of Chester and Ellesmere Port with its waterways museum . The towpath through Chester provides an attractive route for walkers. The canal is well connected, with links to the Trent and Mersey Canal via the Middlewich Branch to the east, the Staffordshire and Worcestershire Canal via the former Birmingham and Liverpool Junction Canal to the south, and provides a route to the Llangollen Canal, from which

16652-549: The company accepted £246,500. A rival group were proposing canals to the east, which resulted in the first group proposing a direct link with the Chester Canal from their Whitchurch Branch, and in February 1793, the two groups amalgamated. On 30 April they obtained an act of Parliament ( 33 Geo. 3 . c. 91) authorising them to raise £400,00 with an additional £100,000 if necessary. Jessop was assisted by John Duncombe, Thomas Denson and William Turner, and from 30 October, Thomas Telford

16833-402: The construction of a cut from Frodsham to Weston Point. The trustees insisted that their own engineer, John Johnson, should oversee the work, but the project was too large for him, and ran over time and budget. He was sacked in 1809, after serving the navigation for 29 years, and Thomas Telford was asked to complete the work. He managed the project with Samuel Fowls as engineer. At Weston Point,

17014-407: The construction of a series of cuts, with locks and weirs to manage the drop of around 50 feet (15 m) over the 20 miles (32 km) between Winsford and the River Mersey. Barges of up to 40 tons could reach Winsford, and boats called Weaver flats were the predominant vessels. These either sailed up the river, or were bow-hauled by teams of men. The navigation was not initially profitable, and

17195-424: The cost of materials increased. Losses escalated, to £153,318 on an income of £227,845 in 1920, and carriage by the company ceased in 1921, in an attempt to reduce losses. 433,230 tons of goods carried in 1929 had dropped to 151,144 tons in 1940, by which time income from tolls was £17,763, and total income was £40,985. The River Dee branch heads eastwards from the river, and passes through two locks before turning to

17376-408: The directors of the Chester canal saw this as a chance to make the canal profitable again, and to build the Middlewich branch. Following the chairman's report to a meeting of the shareholders, they resolved to try to raise some money to carry out repairs, any by the end of the year reported that the canal was "nearly filled with water and business begins to stir." The Ellesmere scheme was extensive, with

17557-399: The drop follows an s-shaped curve to create a smooth transition and reduce turbulence . However, this smooth transition does not dissipate the water's kinetic energy, which leads to heavy scouring. As a result, the canal needs to be reinforced with concrete or masonry to protect it from eroding. Another type of canal fall is the vertical fall, which is "simple and economical". These feature

17738-467: The east of the locks has a walkway supported by rusticated piers and five cast iron arches, which also support the floodgates. The structure is Baroque in style. Northwich railway viaduct spans both the lock cut and the weir stream, and was built in the 1860s. It consists of 48 round arches, constructed of blue bricks and red sandstone, with iron spans over the channels. It is around 980 yards (900 m) long, provides 39 feet (12 m) of headroom over

17919-491: The existing canals were converted, the company was leased to the London and North Western Railway , who took control in June 1847. They allowed the Shropshire Union to continue to operate fairly independently, and by 1849, the idea of conversion had been dropped, as the canals could still operate profitably. Profitability was maintained, with the result then when most of the Shropshire Union network of canals were abandoned in 1944,

18100-503: The first of five locks which raise the level of the canal by another 43.3 feet (13.2 m) is reached. Between the fourth and fifth locks, the North Wales Coast railway line to Crewe crosses under the canal in a tunnel. The canal passes along the south-western edge of Christleton , and through the centre of Waverton , where there is a large grade II listed mill building, which was once steam powered and includes bays in

18281-670: The first summit level canal to use pound locks in Europe was the Briare Canal connecting the Loire and Seine (1642), followed by the more ambitious Canal du Midi (1683) connecting the Atlantic to the Mediterranean. This included a staircase of 8 locks at Béziers , a 157 metres (515 ft) tunnel, and three major aqueducts. Canal building progressed steadily in Germany in the 17th and 18th centuries with three great rivers,

18462-603: The first time in over 100 years. It was designated as a cruising waterway in the Transport Act 1968 , with potential for leisure use, and since then, it has been enjoyed by recreational boaters, by walkers and by fishermen. In 1997, the Chester Canal Heritage Trust was formed and has worked to promote the canal and its heritage. Responsibility for the canal passed from British Waterways to the newly formed Canal & River Trust in 2012. In 1771,

18643-494: The former Chester Canal. Receipts for the Ellesmere Canal were £12,568 in 1807 and £15,707 just two years later. In 1836, a review of trade on the canals showed that limestone from Llanymynech and coal from Chirk was used to produce lime at a number of locations along the canals. Coal from Chirk for industrial and household use was carried, although there was a competing trade in coal from Flintshire, which travelled along

18824-462: The freedom to make deliveries well away from rail lined road beds or ditches in the dirt which could not operate in the winter. The longest extant canal today, the Grand Canal in northern China, still remains in heavy use, especially the portion south of the Yellow River . It stretches from Beijing to Hangzhou at 1,794 kilometres (1,115 miles). Canals are built in one of three ways, or

19005-428: The great aqueduct at Pontcysyllte running roughly northwards through Ruabon, Bersham, Gwersyllt and Pulford to join the River Dee opposite the canal basin at Chester. The Chester company, who were trying to put their financial affairs into order, noticed that the 1796 act failed to mention a connection with their canal. They decided to obtain an act of Parliament to enforce a connection, and to stop supplying water to

19186-720: The higher waters of the Charles River and the mouth of the Neponset River and the sea. It was constructed in 1639 to provide water power for mills. In Russia, the Volga–Baltic Waterway , a nationwide canal system connecting the Baltic Sea and Caspian Sea via the Neva and Volga rivers, was opened in 1718. Weaver Navigation The River Weaver is a river, navigable in its lower reaches, running in

19367-576: The historic building in which it is housed, and a visitor centre at the Anderton lift, which is popular with boaters and non-boaters alike. There are, however, few facilities for the recreational boater. Rowing is popular on the River Weaver, with competitive clubs in Runcorn , Northwich , and Acton Bridge (The Grange School). Fishing is another pastime which takes place along the river. Several clubs lease fishing rights for different parts of

19548-414: The history of the canal and publish the results as a book. In 2012, responsibility for the canal passed from British Waterways to the newly formed Canal & River Trust . Although the Chester Canal was not a success as traffic was sparse, this changed once it was connected to the Ellesmere Canal. The Ellesmere company expected to carry limestone from the quarries at Llanymynech and Trevor , iron from

19729-514: The inland waterways system would have serious repercussions on the parts left. Robert Stephenson suggested that a number of railways and canals should amalgamate, to reduce competition when bills were presented to Parliament. The canals to join the Ellesmere and Chester Company were the eastern and western branches of the Montgomeryshire Canal , the Shrewsbury Canal and the Shropshire Canal . Although some would be converted to railways,

19910-401: The insecticide cypermethrin , all substances which did not form part of the quality checks prior to 2019. In August 2012, oxygen levels in the river were found to be low, following the death of thousands of fish. The Environment Agency were notified and aerated the water while they investigated the cause of the problem. This was thought to result from naturally occurring algae, which deplete

20091-462: The intermediate gates. These are the last locks before the end of the Chester canal, and are the last locks which wide-beam boats can use when travelling south. As the canal approaches Barbridge Junction , the railway turns away, heading east, and the canal turns towards the south. The junction is the start of the Middlewich Branch , which descends through four locks to reach the Trent and Mersey Canal at Middlewich. After another 1.3 miles (2.1 km),

20272-417: The ironworks at Ruabon and Bersham , and coal from mines at Chirk , Ruabon and Wrexham to Chester, Liverpool and Shrewsbury . The canal to Bersham and Wrexham was not built, and that to Shrewsbury was built much later on, but trade in coal, limestone, lime and building materials developed within the network of canals, and traffic between the canals and Liverpool increased steadily, much of it passing along

20453-420: The line that had been built. They attempted to mine salt at Nantwich, but failed to find any, and tried running boats on the Trent and Mersey, from which goods were carried over land to Nantwich, for onward carriage to Liverpool. They also ran boats for cargo and passengers on the canal itself. By the end of 1781, the company had no money and was unable to meet interest payments on the loans. They decided to forfeit

20634-549: The load were carried by a barge on a waterway, then up to 30 tons could be drawn by the same horse. — technology historian Ronald W. Clark referring to transport realities before the industrial revolution and the Canal age . Hohokam was a society in the North American Southwest in what is now part of Arizona , United States, and Sonora , Mexico. Their irrigation systems supported the largest population in

20815-423: The lock was raised, but subsidence caused by the salt mining resulted in a new lock being needed in 1826. A longer-term solution was provided by the decision to move Northwich lock to a new site below the town. When the work was finished in 1829, Witton Brook lock was no longer necessary, and was removed. New cuts and locks were built through the 1790s at Vale Royal, Newbridge, Hartford and Hunts, and Butty Meadow lock

20996-499: The locks, a five-arched red sandstone viaduct, constructed in 1837, crosses the valley. It was built by Joseph Locke , and carried the Grand Junction Railway . Hunt's locks also consist of a pair, the smaller one from the 1860s and the larger one, with three sets of gates, from the 1890s. Steel semaphore signals control access to the locks, and again the movement of the gates employs a Pelton turbine. The weir to

21177-480: The longest canal in the world today and the oldest extant one. It is 1,794 kilometres (1,115 mi) long and was built to carry the Emperor Yang Guang between Zhuodu ( Beijing ) and Yuhang ( Hangzhou ). The project began in 605 and was completed in 609, although much of the work combined older canals, the oldest section of the canal existing since at least 486 BC. Even in its narrowest urban sections it

21358-534: The longest one of that period being the Hong Gou (Canal of the Wild Geese), which according to the ancient historian Sima Qian connected the old states of Song, Zhang, Chen, Cai, Cao, and Wei. The Caoyun System of canals was essential for imperial taxation, which was largely assessed in kind and involved enormous shipments of rice and other grains. By far the longest canal was the Grand Canal of China , still

21539-542: The navigation, and also crosses the River Dane . Hayhurst swing bridge carries the A5509 road over the navigation, and was manufactured by A Handyside and Co. Ltd., of Derby and London, in 1899. It is an asymmetric bowstring lattice girder bridge, and its timber-framed weatherboarded control cabin is also listed. This and Town bridge, which is located a little further downstream and is of a similar design, are believed to be

21720-494: The negotiations failed. Three years later, the financial position of the Chester Canal was better, and they began paying off their debts. Finally in 1813, they agreed to amalgamate, and the action was authorised by a further act of Parliament, the Ellesmere and Chester Canals Unification Act 1813 ( 53 Geo. 3 . c. lxxx). The Ellesmere company paid just half of their 1804 offer, and the 500 Ellesmere shares were distributed between

21901-492: The new company retaining the name of the Ellesmere and Chester Canal. Almost immediately, the company began looking at the possibility of converting all or part of the system into railways. W. A. Povis, their engineer, was convinced that railways could be built along the routes at around half the cost of building a new line. The move was opposed by the Staffordshire and Worcestershire Canal who argued that closing bits of

22082-443: The north. Another two locks raise its level to that of the Ellesmere Canal, and the junction was the site of a historic boatyard. Originally, the branch continued eastwards after the first two locks, and another two brought it up to the level of the Chester Canal main line. From the junction, the Ellesmere main line headed south, to another right-angled band where it joined the Chester Canal. There are moorings at Tower Wharf, just before

22263-506: The numbers that once fueled and enabled economic growth, indeed were practically a prerequisite to further urbanization and industrialization. For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising

22444-548: The opening of the Runcorn and Weston Canal , which was completed in 1859. The canal left the Weston Canal at Weston Point, and provided a link to Runcorn Docks , near which two flights of locks connected to the Bridgewater Canal . This link was severed in 1966, when the Runcorn to Widnes road bridge was constructed. Half of the Runcorn and Weston Canal was filled in at the same time. Significant change occurred when

22625-430: The original three undertakers was actively engaged on the project, and he could not reach agreement with the commissioners. The stalemate was broken when Vernon died in 1726, and new undertakers were appointed. The work on the Weaver was completed by 1732, at a cost of £15,885. Eleven timber locks and weirs had been constructed, but no work had been carried out on the Witton Brook. The river had been improved by dredging and

22806-425: The oxygen on which the fish depend, and may also have been affected by a reaction between hydrogen peroxide , which is used to improve oxygen levels in the water, and traces of detergent. The reaction results in an unpleasant-looking foam building up on the surface, although the foam is not hazardous. The Winsford and District Angling Association, who use the river for fishing, believe it will take many years to restore

22987-997: The park. This crossed the road on Nantwich Aqueduct, and joined the canal just to the north of the basin. Dorfold Hall , to the west of the basin, is a grade I listed mansion, built in 1616 for Ralph Wilbraham. As built, the locks on the Chester Canal were originally 80 by 14.75 feet (24.38 by 4.50 m). Over the years the maximum size for vessels using the canal has altered. By 1985, it had been reduced to 72 by 13.25 feet (21.95 by 4.04 m), and in 2009, sizes were quoted as 72 by 9 feet (21.9 by 2.7 m). Download coordinates as: [REDACTED] Media related to Chester Canal at Wikimedia Commons Canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation ) or for conveyancing water transport vehicles (e.g. water taxi ). They carry free, calm surface flow under atmospheric pressure , and can be thought of as artificial rivers . In most cases,

23168-554: The people of Chester, fearing that the construction of the Trent and Mersey Canal would divert trade away from their city to Liverpool , announced in the Press that they would be applying to build a canal between Middlewich , on the Trent and Mersey, and Chester. The city was at the time served by the River Dee , and the River Dee Company had recently spent £80,000 on improvements to the river, but they realised that without

23349-433: The potential for leisure use. By that time there was little commercial traffic. The branch to the River Dee at Chester had been unused since 1932–34, with the demise of steel traffic from Shotton steelworks to Ellesmere Port, and long distance carrying of tar from Ellesmere Port to the Midlands had ended in 1957–58. The canal is popular with pleasure boaters, as much of it is pleasantly rural, with added interest provided by

23530-604: The pre-railroad days of the industrial revolution, water transport was the gold standard of fast transportation. The first artificial canal in Western Europe was the Fossa Carolina built at the end of the 8th century under personal supervision of Charlemagne . In Britain, the Glastonbury Canal   is believed to be the first post-Roman canal and was built in the middle of the 10th century to link

23711-530: The profits being given to the County of Cheshire, as stated in the original act of Parliament. The Trent and Mersey was completed in May 1777, and had an immediate effect on trade, which dropped by 25 per cent, particularly in the Winsford area. The downturn was short lived, as the salt trade developed, figures reaching their former levels by 1783, and climbing another 40 per cent to 171,719 tons by 1790. Ultimately,

23892-448: The provision of a tide lock into the Dee, which made access into the lower basin possible at all times, and helped to keep it free from silt. The Ellesmere Canal company had been constructing canals to the west, linking Llangollen to Frankton, but the route from there to Chester had not been decided. In 1796, they obtained an act of Parliament ( 36 Geo. 3 . c. 71), authorising a line from near

24073-439: The provisions of the 1721 act no longer covered the way in which they were operating, and so a further act of Parliament, the River Weaver Navigation Act 1759 ( 33 Geo. 2 . c. 49) was obtained on 22 May 1760. This changed the way in which the debts were managed, and gave the commissioners powers to sue and to appoint a management committee. It also stipulated that all locks should be 90 by 17.3 feet (27.4 by 5.3 m) with

24254-771: The remains of the Shropshire Union system, including what had been the Chester Canal, were nationalised on 1 January 1948, and became the responsibility of the Docks and Inland Waterways Executive, which was part of the British Transport Commission . At the time, the function of canals was still viewed as commercial. An official reply to the Inland Waterways Association in 1947 stated that the Ministry of Transport "... do not look very favourably upon any scheme for pleasure craft on

24435-549: The right gable from which boats were loaded. The parish church is some distance from the main centre of population, on the edge of the flat Cheshire plain. The tall tower dates from the 16th century, and the roof of the nave is of hammer-beam construction, dating from 1635. There are several accommodation bridges on this section, all dating from the time of the construction of the canal, including Davies Bridge, Salmon's Bridge, and Faulkners Bridge, all built in orange brick and grade II listed structures. The railway line to Crewe follows

24616-551: The river for activities which include youth training and racing of several types of dinghy sailboats. Their training courses are accredited by the Royal Yachting Association . The navigation has a number of structures which, because of their age, have historic value and are listed on the Listed Building register. At Vale Royal, the lock built in 1860 was retained as a sluice channel when a new lock

24797-500: The river from British Waterways, as it holds populations of bream , three types of carp , chub , dace , eels , perch , pike , roach , rudd and tench . Fishing matches are regularly organised at weekends. The lower reaches of the Weaver between Frodsham railway viaduct and the Manchester Ship Canal are used for sailing. The Weaver Sailing Club is based at Frodsham, and uses a 2.5-mile (4.0 km) stretch of

24978-426: The river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates , angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations,

25159-503: The river was obtained by three gentlemen of Cheshire. The act was dated 23 March 1721 and authorised work between Frodsham bridge and Winsford bridge. Rates for tolls were set, which were to be reduced by 20 per cent once the cost of construction had been met, and profits were then to be used to maintain bridges and highways within Cheshire. Each year the justices of the peace were to meet to decide which structures should benefit from this source of revenue. The act included powers to improve

25340-424: The river would cease once the lift was opened, but by the turn of the 19th century, although there were 190,000 tons of cargo using the lift each year, 38,000 tons of salt were still being transferred by chute. From the middle of the 19th century, some of the salt traffic transferred to the railways, and the use of pipelines through which the brine was pumped also affected trade, but as that source of revenue declined,

25521-455: The route from Ellesmere Port to Middlewich via Barbridge Junction was part of the system that would be retained as a waterway, on which salt was a major source of revenue. The plans resulted in the formation of the Shropshire Union Railways and Canal Company in 1846. The new company could raise £3.3 million of new capital, in addition to that already in existence, with another £1.1 million if necessary. They prompted new railways, but before any of

25702-516: The same general alignment as the canal, but a little further to the south, as both follow the valley of the River Gowy . The canal crosses from the south bank of the river to the north bank on an aqueduct and continues eastwards, passing the massive ruined remains of Beeston Castle , which was built in the 1220s by the Earl of Chester on top of a steep hill, and dominates the countryside. The castle

25883-458: The sections which had originally been the Chester Canal, the northern part of the Ellesmere Canal, the Birmingham and Liverpool Junction Canal and the Middlewich Branch were all retained. The only other section which was not abandoned was the Llangollen branch; this was kept because of its function as a water supply channel, rather than for navigation. In common with many operational canals,

26064-558: The ship canal company for taking small boats onto a large commercial waterway are too daunting, and Ellesmere Port acts as the end of their journey. The Chester Canal Heritage Trust was set up in 1997 to promote the canal and its heritage. Among other projects, they have received funding from the Local History Initiative and the Nationwide Building Society , which has allowed them to research

26245-410: The ship canal without having to pass through the docks at Weston Point. All water from the river entered the canal nearby, and any surplus was released into the Mersey through the Weaver sluices, which were located just upstream of the junction. A notable feature is the Anderton Boat Lift , which is near Northwich , and links the Weaver with the Trent and Mersey Canal some 50 feet (15 m) above. It

26426-566: The ship-sized locks remain. For leisure boaters, most of the movable bridges provide a clearance of 8 feet (2.4 m), although the swing bridge at Newbridge, on the Vale Royal cut, only has headroom of 6.3 feet (1.9 m). Boats which require the bridges to be opened must give prior notice. There is a salt museum at Northwich, which was renamed as the Weaver Hall Museum and Workhouse in 2010, to reflect its expanding scope and

26607-399: The six species of fish affected by the incident. Download coordinates as: The following is a list of those named watercourses which enter the river Weaver on its left (L) or right (R) bank. By convention, the left and right banks are as viewed when looking downstream. Tributaries are listed down the page in an upstream direction, i.e. the first tributary listed (Flood Brook) is closest to

26788-480: The standard of living for any industrialized society. Most ship canals today primarily service bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement

26969-458: The time of the 1890s upgrade, and so it retained some of its original features. It is derelict, and water flow is controlled by a concrete and steel sluice erected in the mid 20th century. A red sandstone and limestone bridge carries the A56 road over the channel below the lock. It was built in 1850, and has three 27-yard (25 m) arches. The A56 crosses the main channel on Sutton swing bridge, which

27150-402: The trustees had built a basin, piers and a lighthouse at Weston Point, that the Weston Canal was officially a branch of the River Weaver, and that the trustees would make no additional charges for using the section. No tolls had been collected since 1816, once the construction costs had been repaid. The trustees investigated the idea of a junction canal from Winsford to the Middlewich branch of

27331-491: The two earliest swing bridges in Britain to be powered by electricity. Both bridges were designed by J. A. Saner, who was the Navigation's engineer, and incorporate a sectional pontoon, which is immersed in the river and carries about 80 per cent of the weight of the bridge. Because of the risk of subsidence from the salt workings, the bridges are fitted with screw jacks which allow the deck level to be maintained. Hayhurst bridge

27512-559: The underlying salt mines. It is possible for some canal boats to explore the Bottom Flash, but the depth of water is limited, and great care is needed. The Flash is used for yacht racing by the Winsford Flash Sailing Club, which is based on the 90-acre (36 ha) lake. The Weaver is a river of contrasts, with quiet wooded reaches and heavily industrialised sites. Commercial shipping has largely ceased, but

27693-491: The undertakers, which repaid the outstanding debt and bought the navigation rights. The deal was completed on 11 October 1758. The commissioners largely ignored the survey which had been carried out by Henry Berry, and decided to enlarge the locks to 17.3 feet (5.3 m) wide. Work began on a new cut, lock and weir at Pickerings, but in 1759, the navigation was cut in half by the collapse of a salt pit at Northwich. The commissioners discovered that they could not sue for damages, as

27874-466: The valley of the River Dee . Another option for dealing with hills is to tunnel through them. An example of this approach is the Harecastle Tunnel on the Trent and Mersey Canal . Tunnels are only practical for smaller canals. Some canals attempted to keep changes in level down to a minimum. These canals known as contour canals would take longer, winding routes, along which the land was

28055-492: The various Chester shareholders. The Ellesmere and Chester Canal Company took over on 1 July 1813. A new section of canal and an iron lock were built at Beeston in 1827, to resolve continual problems with leakage there. In 1826, the Birmingham and Liverpool Junction Canal was authorised by an act of Parliament, to construct a canal from Nantwich to a junction with the Staffordshire and Worcestershire Canal at Autherley in

28236-619: The village of Wrenbury , when the Llangollen Canal crosses its course. After flowing through the village, it passes to the west of the Cheshire village of Audlem , where it starts to flow approximately northwards across the Cheshire Plain. Shortly afterwards, the Shropshire Union Canal is carried over it on Moss Hall aqueduct. The first significant town on the river is the market town of Nantwich , where

28417-419: Was 1775 before the first payments were made. Trade continued to rise, and by 1845, over £500,000 had been given to the county. The major trade was salt . The arrival of the Trent and Mersey Canal at Anderton in 1773 was detrimental to the salt trade at first, but ultimately beneficial, as salt was tipped down chutes from the canal into barges on the river navigation. Access to the river was improved in 1810 by

28598-467: Was a single pair of gates, which provided a 15-foot-wide (4.6 m) entrance into a basin from which the canal rose to the Northgate level. The land on which the basin was built was owned by the River Dee Company, who therefore charged tolls on all traffic using it. In 1774, part of an aqueduct collapsed, and had to be dismantled and repaired. Soon afterwards, Weston left the project, and Thomas Morris

28779-421: Was also building branches in North Wales, which were intended to link up to the River Dee at Chester, but eventually linked to the Chester Canal at Hurleston Junction , just to the north of Nantwich, in 1805. The canal then became the middle section of a much longer and more profitable canal. The two companies merged in 1813, becoming the Ellesmere and Chester Canal. When the Birmingham and Liverpool Junction Canal

28960-466: Was also expensive, as men expect compensation in the form of wages, room and board. This was because long-haul roads were unpaved, more often than not too narrow for carts, much less wagons, and in poor condition, wending their way through forests, marshy or muddy quagmires as often as unimproved but dry footing. In that era, as today, greater cargoes, especially bulk goods and raw materials , could be transported by ship far more economically than by land; in

29141-458: Was an option in some cases, sometimes supplemented by other methods to deal with seasonal variations in flow. Where such sources were unavailable, reservoirs  – either separate from the canal or built into its course – and back pumping were used to provide the required water. In other cases, water pumped from mines was used to feed the canal. In certain cases, extensive "feeder canals" were built to bring water from sources located far from

29322-469: Was appointed to set out the line and oversee the construction. Work began on the Wirral line from Ellesmere Port to Chester in November 1793, and packet boats began using most of it on 1 July 1795. The locks connecting it to the River Mersey were completed early the following year, and the connection to the Chester Canal opened in January 1797. The 8.75 miles (14.08 km) line was supplied with water from

29503-462: Was authorised. Once it was, the Ellesmere and Chester company obtained an act of Parliament in 1827, but the Trent and Mersey insisted that they build a short connecting canal, the Wardle Canal , consisting of a lock and not much more, the tolls for which were exorbitant. The 1827 act repealed all previous legislation for the Ellesmere and Chester Canals and consolidated their position. The branch

29684-408: Was built as a narrow canal, and cost £129,000. It opened on 1 September 1833, but was little used until the Birmingham and Liverpool Junction Canal was completed. It finally opened on 2 March 1835, having suffered from engineering problems during construction. Again, it was a narrow canal, suitable for boats which were 7 feet (2.1 m) wide. The two canal companies worked together from the start, in

29865-416: Was built in the 1890s. A swing bridge crosses the chamber. The sluice at the upstream end is supported by two cast iron arches on rusticated piers. A swing bridge, made of wood and iron, crosses the small lock, which was the large lock until the construction of the new large lock in the 1890s. This has three sets of gates, and could accommodate a train of four barges when the outer gates were used. Again,

30046-424: Was built in the 1920s. There have been problems with the stability of the road surface, and options to secure its long-term future and appearance were discussed in 2010. A £4.5 million restoration project began in the summer of 2013, with the construction of a temporary bridge to carry the traffic while the swing bridge was refurbished. Work included fitting a new deck and renovation of the buoyancy tanks on which

30227-401: Was built over the top of the old one, so that it could continue to be used until the new one was ready, and the work was carried out by staff of the Navigation, supervised by the engineer J. A. Saner. It was completed in 1906, and continued in use until 1983, when it was closed on safety grounds due to corrosion. It had been expected that use of the chutes to transfer salt between the canal and

30408-532: Was completed in 1765. The proposed Trent and Mersey Canal was seen as a threat by the Trustees of the Navigation, for it ran parallel to the River Weaver for some distance near Anderton. However, the commissioners pressed on with upgrading the river, completing new locks at Barnton in 1771 and at Acton Bridge in 1778. They also set about repaying their debts, which were liquidated in July 1775, resulting in some of

30589-437: Was completed under the direction of Joseph Taylor. In September 1776, the junction with the Dee was opened, but the project was now in financial difficulties. By late 1777, they had spent all of the share capital of £42,000 and another £19,000, which had been raised as a loan guaranteed by Samuel Egerton of Tatton. He was a shareholder in the company and related to the Duke of Bridgewater. They applied for another act of Parliament,

30770-411: Was expanded in the 1870s, but although turnover increased, operating profits fell dramatically, to just £1,568 in 1876. By 1905, total traffic was 469,950 tons, nearly all of it in boats owned by the company, and between the 1870s and the onset of World War I the company sometimes made a small operating profit and sometimes a loss. Following the end of the war, working hours were cut, wages increased, and

30951-470: Was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster , less geographically constrained & limited, and generally cheaper to maintain railways . By the early 1880s, canals which had little ability to economically compete with rail transport, were off the map. In the next couple of decades, coal

31132-445: Was hampered by financial and engineering problems, and so progress was slow. At the Chester end, the River Dee Company had managed to insert a clause into the act of Parliament which restricted the width of the final lock into the river to 7 feet (2.1 m). Although the lock was built, and some narrow boats capable of using it were constructed, agreement was reached on a wider connection after four years of argument. The solution adopted

31313-526: Was held on its completion, as there had been no deaths and no serious injuries to the workers during its construction. The River Weaver is around 71 miles (114 km) long. From its source in the hills of west Cheshire just south of Peckforton Castle , and within a few hundred metres of the source of the River Gowy it initially flows in a south-easterly direction towards the border with Shropshire , fed by tributaries some of which rise in north Shropshire. The first of three canal crossings occurs just before

31494-424: Was increasingly diminished as the heating fuel of choice by oil, and growth of coal shipments leveled off. Later, after World War I when motor-trucks came into their own, the last small U.S. barge canals saw a steady decline in cargo ton-miles alongside many railways, the flexibility and steep slope climbing capability of lorries taking over cargo hauling increasingly as road networks were improved, and which also had

31675-426: Was once used to describe linear features seen on the surface of Mars , Martian canals , an optical illusion. A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal

31856-455: Was opened in 1875, to allow canal boats to reach the Weaver, and although closed on safety grounds in 1983, it was refurbished and reopened in 2002. Many of the structures of the navigation are of historical importance, and are grade II listed . They include the Hayhurst swing bridge and Northwich Town bridge, which are believed to be the earliest swing bridges powered by electricity. Both have

32037-506: Was proposed in 1826, which would provide a link from Nantwich to Wolverhampton and the Birmingham canal system, the company saw it as an opportunity to build the Middlewich Branch , which would provide a connection to Manchester and the Potteries. The branch opened in 1833, and the Junction Canal opened in 1835. Amalgamation followed in 1845, with the new company retaining the name of the Ellesmere and Chester Canal. The following year,

32218-470: Was recalled from Ireland to take over. He had previous experience building the extension of the Bridgewater Canal to Runcorn. Under his direction, the canal opened from Chester to Huxley Aqueduct on 16 January 1775, and to Beeston in June. Morris was sacked in September, to be replaced by Josiah Clowes . He too was sacked, and was followed by Moon, who had previously acted as assistant to Morris. The canal

32399-435: Was refurbished in 2004 at a cost of £33.5 million. Winnington bridge, the next downstream, was built between 1908 and 1909, to replace the first bridge which was built in 1901. The original design was flawed, and hence the bridge was replaced after only 7 years. A pedestrian walkway was later fitted on the downstream side of the new bridge. Saltersford locks were built in 1874, using red sandstone and limestone , and replaced

32580-473: Was removed. In response to petitions, the construction of a towing path suitable for horses was started in 1792, and was completed as far as Anderton by mid-1793. It was later extended to Winsford, and bow-hauling of boats by men was ended. Below Frodsham, barges carrying salt had to negotiate a tidal section of the river to reach the Mersey, from where the cargo would be taken to Liverpool or Manchester for distribution worldwide. Water levels were inadequate for

32761-436: Was then started on making the river 7.5 feet (2.3 m) deep throughout, and building double locks suitable for 100-ton vessels which were 88 by 18 feet (26.8 by 5.5 m). By 1845, Winnington, Acton and Hunts locks had been improved. Trade was good, with tolls generating £38,363 in 1845 from the carriage of 778,715 tons of goods. All of the improvements had been funded from the toll revenue, and over £500,000 had been given to
