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 Ashop is a river in the Derbyshire Peak District, England. Its source is on the eastern slopes of Mill Hill, three miles south east of Glossop and just north of Kinder Scout.The river flows approximately ten kilometres east, following the Sheffield to Manchester Snake Pass road through remote countryside, before emptying into Ladybower Reservoir, which itself flows into the River Derwent.
