The Sulby Reservoir is the largest reservoir or lake in the Isle of Man.
Dam
The reservoir's dam was completed in 1982. It has a rock-fill embankment 73 metres (240 ft) high.
Geography
It is located in Sulby Glen near the source of the Sulby River, the longest river on the island. It is at the foot of Druidale, Glen Crammag, and a third, unnamed minor valley. It is at the junction of three parishes: Michael, Lezayre and Braddan. Sulby Reservoir is also about 1.5 miles (2.4 km) west of the summit of Snaefell, the island's highest peak. It is operated by the Isle of Man Water Authority.[1]
Use
The reservoir supplies St Johns, Peel, Kirk Michael, Ballaugh, Andreas, Bride, Ramsey and Laxey. Water can also be pumped to the West Baldwin Reservoir which supplies Douglas and the south of the island.
The reservoir also powers a hydro-electric power station one mile (1.6 kilometres) downstream. (Water flows through a pipeline from the reservoir to the power station. The power station is also fed by another, smaller reservoir, Block Eary.)
An energy recovery system was installed at the Sulby Water Treatment Works in 2013, to generate hydro-electric power from incoming water.
