Clatworthy Reservoir is located on the edge of the Exmoor National Park in west Somerset and covers around 130 acres. An Iron Age hill fort stands on the promontory above the reservoir. The reservoir itself is used for fishing for rainbow and brown trout from the banks or by boat. It’s possible to walk the entire perimeter of the reservoir, covering 8 km (5 mi), or there is a shorter nature trail available.
The site supports a range of habitats including acid grassland, broadleaf woodlands and scrub and marshy areas around the inlet streams. The woodland around the reservoir, inhabited by red and roe deer and badgers amongst other fauna, is mainly beech, sessile oaks, silver birch and rowan. Birds to be found on the water include geese, grebes and swans. No dogs are allowed in the vicinity of the water.
