Winscar Reservoir (also known as Winscar dam), is a compensation reservoir on the headwaters of the River Don in South Yorkshire, England. The reservoir is located at Dunford Bridge in Barnsley 25 miles (40 km) northwest of Sheffield,[3] and is just inside the Peak District National Park on the Pennine watershed. The reservoir was built on an existing dam and has suffered from leaking which necessitated a new membrane being installed at the dam head in the years 2000 and 2001.
It was the first major dam to be built in England with an asphaltic concrete membrane on the upstream dam wall and was the last dam to be built that was fed from the River Don.
