The Norton Dam (also sometimes called the Norton Bridge Dam) is the gravity dam built across the Kehelgamu Oya, which is a main tributary to the Kelani River. The dam is built at Norton Bridge, in the Central Province of Sri Lanka.[1]
The dam creates the relatively small Norton Reservoir, which is sustained by water from the Kehelgamu Oya, and water discharged from the Wimalasurendra Hydroelectric Power Station, which is located upstream of the reservoir. The Wimalasurendra Power Station or the Norton Bridge Power station is fed from the reservoir at Castles Reigh about 2000 feet above the Norton Reservoir.
Water from the Norton Reservoir is further channelled through a Tunnel through the rock strata and then by a couple of steel pipes penstock to the Hydroelectric Power Station, located 3.81NaN1 downstream at, 1.51NaN1 northwest of Kiriwan Eliya. The power station consists of five hydroelectric generators, three of which are rated at, and two of which are . The first three and last two units were commissioned in and, respectively.[2]
