Ladybower Reservoir

Ladybower Reservoir is a large Y-shaped reservoir, the lowest of three in the Upper Derwent Valley in Derbyshire. The dam's design is unusual in having two totally enclosed bell-mouth overflows (locally named the "plugholes") at the side of the dam wall. These are stone and of 80 feet (24 m) diameter with outlets of 15 feet (4.6 m) diameter. The overflows originally had walkways around them, but they were dismantled many years ago. The bell mouths are often completely out of the water and are only rarely submerged, usually after heavy rainfall or flooding.

Address: Start at Heatherdene Car Park off the A6013 Bamford road.

Ordnance Survey grid reference: SK 2023 8588

Postcode: S33 0BY

Open: No restriction

Entry cost: Access to the reservoir and walks is free of charge but the car park is not.

Useful info: There are a number of other car parks around the reservoirs if the one nearest the plugholes is full, but they are a fair walk away.
