Dale Dike reservoir and dam

Dale Dike Reservoir or Dale Dyke Reservoir, famous for causing the Great Sheffield Flood, is in the north-east Peak District, in the City of Sheffield South Yorkshire, England, a mile (1.6 km) west of Bradfield, eight miles (13 km) from the centre of Sheffield, on the Dale Dike, a tributary of the River Loxley.

Along with three other reservoirs around the village of Bradfield - Agden, Damflask and Strines - it was constructed between 1859 and 1864 by the Sheffield Waterworks Company to guarantee a supply of water to power the mills downstream and to supply drinking water to the growing population of Sheffield.
