45-632: The River Granta is the name of two of the four tributaries of the River Cam , although both names are often used synonymously. The Granta starts near the village of Widdington in Essex , flowing north past Audley End House to merge with the other contributary Rhee, which is also commonly called River Cam, a mile south of Grantchester. From source to its confluence with the Rhee it is 41.7 kilometres (25.9 mi) in length. A further tributary, also known as
90-693: A community who call themselves the Camboaters. Navigation on the lowest section of the Cam, below and including Bottisham Lock, is the responsibility of the Environment Agency . The stretch above Jesus Lock is sometimes known as the middle river (with the section above the Mill Pond being referred to as the upper river). Between Jesus Lock and the Mill Pond, it passes through the Backs below
135-540: A further kilometre. At this point its course turns east and from here until it merges with the Granta it forms the parish boundary between a succession of villages, though until it reaches Barrington it remains at a distance of around a kilometre from any settlement of any size. Just after flowing under the Roman Ermine Street , it crosses the avenue of Wimpole Hall and a few kilometres later it receives
180-414: A maximum of eleven, had powers to mortgage the tolls, in order to raise capital for improvements to the river immediately. This they did, and built sluices at Jesus Green, Chesterton, Baits Bite and Clayhithe. Most of the tolls were collected at Clayhithe. Prior to 1722, Denver sluice had been destroyed, and although Cambridge Corporation opposed its reconstruction, it was rebuilt by 1750. The river entered
225-491: A period of steady profitability, with toll receipts rising from £432 in 1752 to over £1,000 by 1803. In 1835 they peaked at £1,995, and then declined slightly until 1846. The Convervators also raised some revenue from rents on the public houses which they owned adjacent to each of the sluices. Another Act of Parliament was obtained on 21 July 1813 which allowed the Conservators to alter the tolls and charge penalties, while
270-565: A person to operate them. The colleges and at least one private operator also own punts which are available for members of the public to travel on. Canoeing and kayaking , both recreational and competitive, are popular at all times of year, especially on the section above the Mill Pond towards Grantchester. Both Cambridge Canoe Club (on Sheep's Green ) and Cambridge University Canoe Club (just upstream from Newnham ) are based here. Powered boats may navigate as far upstream as La Mimosa restaurant (next to Jesus Green) all year round, and as far as
315-532: Is called "Granta" above and "Cam" below it. In earlier times even the lower part of the Cam was also named the Granta, but after the name of the Anglo-Saxon town of Grantebrycge had been modified to Cambridge, the river was renamed to match. Grantchester and Granta Park are on the river banks of the river Granta and their names refer to the river itself. The literary magazine Granta , founded in 1889 by students at Cambridge University as The Granta,

#1732766281098540-651: Is not murky and is clean enough from its source to its confluence with the Great Ouse to support fish. The fishing rights on the west bank are leased annually to the Cambridge Fish Preservation and Angling Society. The Cam below Bottisham Sluice may still hold burbot , a fish thought to be extinct in English waters since the early 1970s. The last known burbot caught in Britain was in 1969, on
585-410: Is prohibited above 'La Mimosa' Pub (at the upstream end of Jesus Green ) between 1 April and 30 September, when the middle and upper river are open only to manually propelled craft. The most common of these are the flat-bottomed punts . Between 1 October and 31 March powered boats are allowed as far as Mill Pool, but few people take advantage of this, as there are very few public mooring places along
630-416: Is sometimes called the lower river. The stretch between Jesus Lock and Baits Bite Lock is much used for rowing . There are also many residential boats on this stretch, their occupants forming a community who call themselves the Camboaters. The stretch above Jesus Lock is sometimes known as the middle river. Jesus Lock footbridge on the Cam links Chesterton Road with Jesus Green for pedestrians next to
675-576: The Conservators of the River Cam was formed in 1702, charged with keeping the river navigable. The Conservators are responsible for the two locks in and north east of Cambridge: Jesus Lock and Baits Bite Lock. The stretch north (downstream) of Jesus Lock is sometimes called the lower river. The stretch between Jesus Lock and Baits Bite Lock is much used for rowing . There are also many residential boats on this stretch, their occupants forming
720-519: The Granta and (unusually) its present name derives from the city of Cambridge ( Old English : Grantebrycge ) rather than the other way around: After the city's present name developed in Middle English , the river's name was backformed to match. This was not universally applied, however, and the upper stretch of the river continues to be informally known as the Granta . It has been said that
765-417: The River Cam in the north of central Cambridge , England. This is Lock No. 1 on the navigable portion of the River Cam. It was built in 1836 and is the only lock in the city. Jesus Green Lock Cottage, the former lock-keeper's cottage, is by the lock on Jesus Green. It is owned by the Conservators of the River Cam and is rented out to students. The lock is located north of Jesus Green , which itself
810-656: The Association in 1643 regulated use of the river for trade, but the biggest change was the construction of Denver Sluice on the River Great Ouse, which reduced river levels on the lower river as tidal waters were excluded from the Ouse. Both the university and the Corporation of Cambridge complained to Parliament in 1697 that the trade route to the town from King's Lynn had been severely impaired. In 1699,
855-465: The Backs, and the river is too narrow and the bridges too low to afford easy passing or turning for many boats. Punts and canoes can be manhandled around the weir above the Mill Pool by means of the rollers, a slipway from lower to upper level. From the Mill Pool and its weir, the river can be followed upstream through Grantchester meadows to the village of Grantchester and Byron's Pool, where it

There is a public slipway next to the garden of the Green Dragon pub in Water Street, Chesterton . This is occasionally used for launching small boats. Punting is the most popular form of boating on the stretch of the river between Jesus Lock and Grantchester. Several of the colleges own punts, and they can also be hired from various companies, either with or without
1035-439: The Corporation sought to obtain an Act of Parliament which would allow them to improve the river from Clayhithe to Queens Mill at Cambridge. This was obtained on 27 February 1702 and created the Conservators of the River Cam, a legal body with authority to charge tolls for use of the river, which ranged from four shillings (20p) a ton for wine to one penny (0.4p) per person for passengers. The Conservators, of which there were

As the university colleges rose in importance, the course of the river through the town, known as the Backs, was moved further to the east to accommodate their new buildings. A report conducted in 1618 by Richard Atkyns highlighted the problems caused by sandbanks above Clayhithe and watermills obstructing navigation. An order made by the parliamentary Committee of
1260-461: The River Cam. The Cam is normally a placid river but flooding does occasionally happen. The most recent serious floods were in 2001, first in February and again on 22–23 October, and then in February 2009.

The Rhee tributary is also formally known as the Cam, and the Granta has a tributary on its upper stretch also known as the Granta. On Ordnance Survey maps, the two main tributaries' alternative names are recognised: "River Cam or Granta" and "River Cam or Rhee". The Cam has no connection with the much smaller River Cam in Gloucestershire . An organisation called

Motorised craft can navigate along the Backs in winter, but headroom is severely restricted. The Conservators of the River Cam now have an office in the former lock-keepers cottage at Baits Bite, while
1800-536: The sea is about 40 mi (64 km) and is navigable for punts, small boats, and rowing craft. The Great Ouse also connects to England's canal system via the Middle Level Navigations and the River Nene . In total, the Cam runs for around 69 kilometres (43 mi) from its furthest source (near Debden in Essex ) to its confluence with the Great Ouse. The original name of the river was

A couple of miles later it forms a picturesque addition to views of the stately home as it flows past the front of Audley End House , and is also joined by
1980-445: The walls of many of the colleges . This is the section of river most popular with tourists, with its picture-postcard views of elegant bridges, green lawns and graceful willows. This stretch also has the unusual feature of the remains of a submerged towpath : the riverside colleges did not permit barge horses on the Backs, so the beasts waded up the Cam to the mill pulling their loads behind them. Access for mechanically powered boats
