Nutscale Reservoir is a reservoir located in Exmoor in north west Somerset, England. It was intended to supply the town of Minehead and nearby Porlock and Porlock Weir. [1] The reservoir is part of the River Horner catchment area and is fed by Nutscale Water . The reservoir is no longer used for public drinking water supply. [2]
The reservoir was built in 1942. [3] A mass concrete gravity arch dam, 90m along the crest and 14m high [4] impounds 36,000,000 imperial gallons (160,000,000 L; 43,000,000 US gal). This was intended to relieve summer droughts in Minehead. [5]
High levels of geosmin were recorded in 2008. [6] To manage the effects of this on tap water systems were developed to remove this reservoir from the drinking water supply when necessary and flush the pipe carrying the water. [7]
The site is operated by Wessex Water whose drought plan suggests that six months would be required to bring Nutscale back into supply operations in a severe drought. [8]
The fishing rights to the reservoir are owned by the National Trust, as part of its Holnicote Estate, and leased out privately. [9]
