Reservoir and power station
The dam creates the iconic Castlereigh Reservoir, which is almost entirely maintained by the inflow of water from the Kehalgamu Oya. Water from the reservoir is diverted to the Wimalasurendra Power Station, located approximately 12 km (7.5 mi) further downstream at 06°54′31″N 80°31′30″E, near Norton Bridge. The power station discharges the water into the Norton Reservoir, created by the Norton Dam, located at the same site.[1]
The power station consists of two 25-megawatt units, totalling the plant capacity to 50 MW. Both units were commissioned in January 1965.[2]
Water airport
The Castlereigh Reservoir is also home to the Castlereigh Water Airport, registered under the IATA code NUF.[3]
