24-555: The Hambleton Peninsula lies within the reservoir Rutland Water , in Rutland , England . When the Gwash Valley was dammed in 1975, the area surrounding what was then a ridge was submerged, including a small number of properties in the hamlets of Nether Hambleton and Middle Hambleton. The village of Upper Hambleton survived, and now sits on the peninsula, which is some 3500 metres in length and 1000 metres in width. The area of

48-401: A fixed structure to which sensors and sampling devices can be affixed. The depth of the structure below water level allows for study of the various layers of water in the lake or reservoir . The management of limnological conditions can be important in reservoirs used to supply drinking water treatment plants. In certain conditions algal blooms can occur which can block filters, change

72-699: A location in Rutland is a stub . You can help Misplaced Pages by expanding it . Rutland Water Rutland Water is a reservoir in Rutland , England, east of Rutland's county town, Oakham . It is filled by pumping from the River Nene and River Welland , and provides water to the East Midlands . By surface area it is the largest reservoir in England, but its capacity is exceeded by that of Kielder Water in Northumberland . Its maximum depth

96-506: A net input to the lake but its flow downstream is maintained. Most of the stored water is extracted from the River Welland at grid reference TF017060 , between Tinwell and Stamford , and from the River Nene upstream from Peterborough , a city which is a major user of the water. Because much of the valley is clay, material for the dam was extracted from pits dug within the area that would be subsequently flooded. The clay dam

120-605: A skeleton measuring about 10 metres in length and a skull weighing about a tonne, is the largest and most complete fossil of its kind found in the UK. The Anglian Water Birdwatching Centre, located in Egleton , features a gift shop operated by Anglian Water and a shop selling binoculars and telescopes. The centre includes the Rutland Environmental Education Centre, exhibits, and windows overlooking

144-429: Is 115 feet (35 m) high, and around 1,300 yards (1,200 m) long. At its base, it is up to 890 yards (810 m) wide, and the finished structure has been landscaped to blend in with the environment, even when viewed from Empingham, the nearest village. Rutland Water contains a limnological tower for study of the reservoir's ecological conditions. Upper Hambleton and the remnant of Middle Hambleton, including

168-480: Is 33m (108 ft). Set in 3,100 acres (13 km ) of countryside, it has a 23-mile (37 km) perimeter track, (17-mile (27 km) excluding Hambleton Peninsula ) for walking or cycling. Since the water is drawn upon when needed, the relative areas of land and water vary a little, but the flatter parts of the lake margin are enclosed by banks so that the wetland nature reserve is maintained ( grid reference SK886073 ). A 1,555 hectare area of lake and shore

192-615: Is a biological Site of Special Scientific Interest , and a Nature Conservation Review site. An area of 1,333 hectares is an internationally important wetland site under the Ramsar Convention , and 393 hectares at the western end is managed by the Leicestershire and Rutland Wildlife Trust . The reservoir's construction, by damming the Gwash valley near Empingham , was completed in 1975. During its construction it

216-512: Is a measure of algal content) at 2m depth intervals. The tower also has the ability to draw water samples for further testing from the various depths and also mounts an automatic weather station. The data is continuous and displayed visually in real-time at the reservoir control centre, situated at the dam. The site of the tower was chosen to best suit the needs of the operator. The reservoir consists of two arms – northern and southern – and has been designed such that all nutrient-rich water enters

240-616: Is home to the Anglian Water Bird Watching Centre. Every August, the centre was the venue for the British Birdwatching Fair until 2019. Other birds found here include lapwing , coot , goldeneye , tufted duck , pochard , teal , wigeon , cormorant , great crested grebe , little grebe and, most notably, osprey , which were re-introduced to the area during 1996, including one called " Mr Rutland ". In 2021 there were 26 ospreys in

264-576: The pH of the water and cause taste and odour problems. If the sensors extend to the bed level the tower can also be used to monitor the hypolimnion (lowest layer of water) which in some conditions can become anoxic (of low oxygen content) which may affect the lake ecology . Limnological towers have been constructed in reservoirs used to supply drinking water in the United Kingdom since algal blooms began causing problems with water quality. By providing data on water conditions and algae levels

288-426: The 1960s. One, 24 metres (79 ft) high was built 4 kilometres (2.5 mi) offshore in 1961 and a second 47 metres (154 ft) high in 1969. They are poles anchored to the lake bed by means of a gimbal and braced by tensioned cables and anchor guys. They featured a mobile thermistor sensor that could be moved to any depth on the tower as well as fixed thermometers at various depths and were intended to monitor

312-456: The Old Hall, are together now known simply as Hambleton and are to be found on a long peninsula in the middle of the lake, land that was formerly a ridge between the two valleys in which the lake now lies. The few houses of Normanton avoided flooding although its church did not. The lower part of the building was supported against water damage so that its upper part could be used to present

336-529: The area of Rutland Water. The lake is stocked with brown trout and rainbow trout, but there is a large head of coarse fish populated by water pumped in from the River Welland and River Nene, species include roach , bream , pike , zander , perch , eel , wels catfish and carp . In early 2021 an ichthyosaur fossil was discovered during the routine draining of a lagoon at the reservoir by nature reserve manager Joe Davis. A Temnodontosaurus with

360-873: The behaviour of the reservoir over a period from a few hours to a few years. Six combined limnological and meteorological observation towers were established in the Great Lakes on the US-Canadian border in 1961. Three were installed in Lake Huron , two in Lake Ontario and one in Lake Erie by the Great Lakes Institute. These were innovative in design and cheap to construct, being built largely from 4-inch (100 mm) water pipe. Constructed in water depths of 7–63 metres (23–207 ft)

384-415: The lake. Birdwatching brings visitors from far afield. Large areas of wetland (as well as several small woods) at the western end of the lake form a nature reserve , managed by Leicestershire and Rutland Wildlife Trust . The area is designated a Special Protection Area of international importance for its wintering populations of gadwall (some 4% of this species’ European population) and shoveler . It

408-518: The peninsula lies in the parish of Hambleton with the exception of a small detached area of Exton parish on the north shore. The Hambleton Peninsula and its surroundings feature heavily in British author Robert Goddard ´s fictional mystery thriller Set in Stone (1999). 52°39′N 0°38′W  /  52.65°N 0.64°W  / 52.65; -0.64 This geographical article about

432-438: The southern arm. The intention being that nutrients will be depleted before the water is abstracted for use at the eastern end of the site. The northern-arm is fed by nutrient-poor sources and should be relatively unaffected by algal blooms. A secondary outlet is available that draws solely from the northern arm, in cases that the southern arm is affected by algal growth. Additionally the operators are able to draw directly from

456-495: The story of the construction of the reservoir to the public. Some funerary monuments from it can be seen at Edenham church, Lincolnshire. The reservoir is used not just for water storage, but is a popular sports centre – as well as water sports such as sailing , visitors enjoy fishing , walking and cycling along a 25 miles (40 km) perimeter track. A pleasure cruiser, the Rutland Belle , carries people around

480-725: The temperatures of different water layers in the lake. A concrete limnological tower was installed at Rutland Water , England's largest reservoir by surface area, when it was built in the early 1970s. The design of the tower was influenced by consultation with the Water Research Centre and was intended to provide the best possible tools to monitor the ecological conditions of the reservoir so that it could be best managed by its operator (the Anglian Water Authority ). The tower monitors water temperature, dissolved oxygen levels and water fluorescence (which

504-400: The towers can predict the behaviour of the algae and allow managers to make decisions to alter conditions to prevent algal blooms . These decisions may include altering water inflows (particularly where nutrient-rich intakes are considered), activating water jets to promote the mixing of different layers of water and altering the depth from which water is abstracted. These decisions can affect
