Description
Area, 33.8 hectares 83.5 ac Description Tophill Low consists of two artificial storage reservoirs situated in the River Hull valley some ten kilometres south west of Driffield. The water stored in the reservoirs is abstracted from the adjacent River Hull and is ultimately used for public supply. The site is important as one of few inland standing open water bodies suitable for wintering wildfowl in North Humberside. Tophill Low reservoirs support nationally important concentrations that is one percent or more of the British wintering population of gadwall, shoveler and tufted duck together with locally important populations of goldeneye, great crested grebe, mallard, pochard, teal and wigeon. The reservoirs also attract a wide range of other wildfowl species throughout the year, particularly during spring and autumn migration.
