The Laxapana Dam is a gravity dam built across the Maskeliya Oya, 2.8 km (1.7 mi) downstream of the iconic Laxapana Falls, in the Central Province of Sri Lanka.[1]

Power station and reservoir

The dam creates the Laxapana Reservoir, which is sustained from water flowing in from the Kelani River, and discharged water from the Old Laxapana Hydroelectric Power Stations and New Laxapana Hydroelectric Power Stations. The Old Laxapana and New Laxapana hydroelectric power stations belongs to the Norton Dam and Canyon Dam respectively, delivered via penstocks.

The combined hydro resource of the Laxapana Reservoir is fed into another penstock to a further 7.8 km (4.8 mi) downstream for utilization of power generation at the Polpitiya Power Station, located at 06°58′40″N 80°27′24″E / 6.97778°N 80.45667°E / 6.97778; 80.45667 (Polpitiya Hydroelectric Power Station). The power station, which is also called as the Samanala Hydroelectric Power Station, consists of two generation units rated at 37.50 MW each, both of which were commissioned in April 1969.[1][2][3]
