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.[1]
A 4.2km (02.6miles) penstock from the Maskeliya Reservoir, measuring 30NaN0 in diameter, transfers water directly to the Canyon Hydroelectric Power Station, located downstream. The power station consists of two units, commissioned in and, respectively. Water from the Canyon Power Station is discharged into the Canyon Reservoir, located on the same site.[2] [3]
