group. Over the decades, demand for water increased. Piped intakes were constructed from the rivers Ashop and Alport to the west to feed directly into the Derwent reservoir, but soon demand increased further to the point where another reservoir was required.

The reservoir was completed in 1945. The topographical similarity between the Upper Derwent Valley and the Ruhr Valley of Germany led to the dams being used as a practice environment for the Lancaster bombers of 617 Squadron ( Dam Busters) in 1943 before their attack on the Ruhr dams.
