The Maskeliya Dam (also known as the Maussakelle Dam) is a large gravity dam at Maskeliya, in the Central Province of Sri Lanka. Along with the Castlereigh Dam, the dams are the highest point and beginning of the Laxapana Hydropower Complex, involving a number of dams, penstocks, and hydroelectric power stations. The dam creates the Maskeliya Reservoir over the route of Maskeliya Oya, a major tributary of the Kelani River, which is the 4th longest in the country.
A 4.2 km (2.6 mi) penstock from the Maskeliya Reservoir, measuring 3 m (10 ft) in diameter, transfers water directly to the Canyon Hydroelectric Power Station, located further downstream. The 60-megawatt power station consists of two 30-megawatt units, commissioned in March 1983 and May 1988, respectively. Water from the Canyon Power Station is discharged into the Canyon Reservoir, located at the same site.
Penstocks channel water from the dam to the power station.
