caption_attribution_description: English: Barmby on the Marsh, East Riding of Yorkshire, England, Tidal Barrage at the mouth of the River Derwent.The barrage is to stop polluted water from the River Ouse getting into the River Derwent. Water is pumped out of the River Derwent at Loftsome Bridge water treatment plant. The water is treated to remove impurities and is used to feed the surrounding district, and feed into the water grid system.
context_page_description: The Derwent is a river in Yorkshire in the north of England.
  It flows from Fylingdales Moor in the North York Moors National Park, then southwards as far as its confluence with the River Hertford then westwards through the Vale of Pickering, south through Kirkham Gorge and the Vale of York, joining the River Ouse at Barmby on the Marsh. The confluence is unusual in that the Derwent converges on the Ouse at a shallow angle in an upstream direction.
  The old course of the river used to flow further east, entering the Ouse east of Howden.
  The River Derwent catchment area includes the Upper Derwent, River Rye, River Hertford, Bielby Beck and Pocklington canal and their tributaries. It covers an area of 2,057 square kilometres and includes the towns of Stamford Bridge, Malton, Pickering, Helmsley, Filey and Scarborough. The area is bounded by the Cleveland Hills, North York Moors and Hambleton Hills to the north, the Yorkshire Wolds and the coast to the east, the Vale of York to the west and the River Ouse and Humber Estuary to the south. The area around the river is primarily rural in nature with grazing moorland in the upland areas and a variety of agricultural uses at lower levels.
