Completed in 1957, the earth embankment reservoir holds up to 1,550 megalitres (341 million gallons) and covers an area of 40 acres (16ha).

Situated close to Exmoor National Park, and managed jointly by Forestry England and The South West Lakes Trust, Wistlandpound is a popular recreation area, with bird watching, trout fishing, as well as boating and nature walking among the most popular activities.

The Calvert Trust has a centre at the Reservoir, providing holiday and activity facilities for those with disabilities, and their families.

The construction of the reservoir flooded part of the formation of the Lynton and Barnstaple Railway, which can still be seen when water levels are low.

The railway, which is being reconstructed, will follow an alternative route around the side of the reservoir.
