The Upper Derwent Valley is an area of the Peak District National Park in England. It largely lies in Derbyshire, but its north eastern area lies in Sheffield, South Yorkshire. Its most significant features are the Derwent Dams, Ladybower, Derwent and Howden, which form Ladybower Reservoir, Derwent Reservoir and Howden Reservoir respectively.
The Derwent is a river in Derbyshire, England. It is 66 miles (106 km) long and is a tributary of the River Trent, which it joins south of Derby. Throughout its course, the river mostly flows through the Peak District and its foothills.
Derwent Reservoir is the middle of three reservoirs in the Upper Derwent Valley in the north of Derbyshire, England. It lies approximately 10 miles (16 km) from Glossop and 10 miles (16 km) from Sheffield. The River Derwent flows first through Howden Reservoir, then Derwent Reservoir and finally through Ladybower Reservoir. Between them they provide practically all of Derbyshire's water, as well as to a large part of South Yorkshire and as far afield as Nottingham and Leicester.
The Howden Reservoir is a Y-shaped reservoir, the uppermost of the three in the Upper Derwent Valley, England. The western half of the reservoir lies in Derbyshire and the eastern half is in Sheffield, South Yorkshire; the county border runs through the middle of the reservoir, following the original path of the River Derwent. The longest arm is around 1.25 miles (2 km) in length. The reservoir is bounded at the southern end by Howden Dam; below this, the Derwent flows immediately into Derwent Reservoir and subsequently the Ladybower Reservoir. Other tributaries include the River Westend, Howden Clough and Linch Clough.
Ladybower Reservoir is a large Y-shaped reservoir, the lowest of three in the Upper Derwent Valley in Derbyshire, England. The River Ashop flows into the reservoir from the west; the River Derwent flows south, initially through Howden Reservoir, then Derwent Reservoir, and finally through Ladybower Reservoir.
The River Sheaf in Sheffield, South Yorkshire, England, flows northwards, past Dore, through Abbeydale and north of Heeley. It then passes into a culvert, through which it flows under the centre of Sheffield before joining the River Don. This lower section of the River Sheaf, together with the River Don between the Blonk Street and Lady's Bridges, formed two sides of the boundary of Sheffield Castle.
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. They are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level.
The Porter Brook is a river in the City of Sheffield, England descending over 1,000 feet (300 m) from its source among the sedge grass on Burbage moor behind a small farm on Hangram just inside the Peak District National Park in the west of the city at Clough Hollow, near the village of Ringinglow. Porter Brook derives its name from its brownish colour, similar to the colour of Porter, a brownish discolouration obtained as it passes over iron-ore deposits on its course from the source. The headwaters of the Porter Brook were previously culverted in Victorian times, and were opened up through a daylighting (streams) scheme completed in 2013. Close to the source, at the junction of Fulwood Lane and Greenhouse Lane is a Rotary Club funded toposcope, Finder Cairn.
The River Noe is a tributary of the River Derwent in Derbyshire, England. It flows approximately 12 miles (19 km) from its source, the confluence of two streams running off Kinder Scout in the Peak District, east through Edale and then southeast through the village of Hope.
The River Loxley is a river in the City of Sheffield South Yorkshire, England. Its source is a series of streams which rise some 10 miles (16 km) to the north-west of Sheffield on Bradfield Moors, flowing through Bradfield Dale to converge at Low Bradfield. It flows easterly through Damflask Reservoir and is joined by Storrs Brook at Storrs, near Stannington, and the River Rivelin at Malin Bridge, before flowing into the River Don at Owlerton, in Hillsborough. The Loxley valley provided the initial course of the Great Sheffield Flood, which happened after the Dale Dyke Dam collapsed shortly before its completion in March 1864.
The River Medlock is a river in Greater Manchester, England, which rises near Oldham and flows south and west for ten miles to join the River Irwell in Manchester city centre.
Derwent was a village 'drowned' in 1944 when the Ladybower Reservoir in Derbyshire, England was created. The village of Ashopton, Derwent Woodlands church and Derwent Hall were also 'drowned' in the construction of the reservoir.
The River Alport flows for 5.6 miles (9 km) in the Dark Peak of the Peak District in Derbyshire, England. Its source is on Bleaklow, 3 miles (4.8 km) east of Glossop, from which it flows south through the Grains in the Water bog, then over gritstone below the Alport Castles landslide to Alport Bridge on the A57 Snake Pass route from Sheffield to Manchester, where it joins the River Ashop. The Ashop flows into Ladybower Reservoir about 2.5 miles (4.0 km) down the valley, which discharges via the Rivers Derwent and Trent to the North Sea. The source of the Alport is close to the Pennine watershed.
The Ware River is a 35.4-mile-long (57.0 km) river in central Massachusetts. It has two forks, the both of which begin in Hubbardston, Massachusetts. The Ware River flows southwest through the middle of the state, joins the Quaboag River at Three Rivers, Massachusetts, to form the Chicopee River on its way to the Connecticut River.
Ashopton was a small village in Derbyshire, England, in the valley of the River Ashop. The village population was less than 100. Details are included in the civil parish of Aston, Derbyshire. In the early 1940s, the village was demolished to make way for the filling of Ladybower Reservoir.
Rivelin Dams are a pair of water storage reservoirs situated in the upper part of the Rivelin Valley, 5 miles (8 km) west of Sheffield in South Yorkshire, England. The dams are owned by Yorkshire Water and provide water to 319,000 people as well as compensation water for the River Rivelin. They are named Upper and Lower and fall just within the eastern boundary of the Peak District.
Northumbrian Water Limited is a water company in the United Kingdom, providing mains water and sewerage services in the English counties of Northumberland, Tyne and Wear, Durham and parts of North Yorkshire, and also supplying water as Essex and Suffolk Water. It is a wholly owned subsidiary of Northumbrian Water Group.
The Möll is a river in northwestern Carinthia in Austria, a left tributary of the Drava.
The Eller Beck is a small river in North Yorkshire, England, that flows through the town of Skipton and is a tributary of the River Aire. Its channel was heavily modified to supply water to mills in the 18th and 19th centuries, and although all the mills have closed, the water now supplies power to the National Grid, generated by a turbine at High Corn Mill. The beck flows through several underground culverts in Skipton that contribute to the flood risk. To alleviate flooding in Skipton town centre, a scheme involving two flood water storage reservoirs has been designed, but the start of the work to implement it was delayed in October 2014 by a shortfall in funding.
Darna is a minor right-bank tributary of Godavari in the Nashik District, Maharashtra. Rising north of the Kalsubai range, it drains Igatpuri, Nashik and Niphad Talukas of Nashik District. The conjunction with Godavari is situated at Darnasangvi.
