Kalatuwawa Reservoir

Kalatuwawa Reservoir
Kalatuwawa Reservoir (Sinhala: කලටුවාව ජලාශය) is a storage reservoir situated in Labugama-Kalatuwawa Forest Reserve in Colombo District, Sri Lanka. It was built by impounding the flow of the Kalatuwawa Ela for water supply for domestic consumption in Colombo City (Arumugam, 1969). The reservoir along with the nearby Labugama Reservoir is maintained by the Colombo Municipal Council.

History
The weir of the Kalatuwawa reservoir was constructed in 1960 (Kotalawala, 2017).

The reservoir
Kalatuwawa Reservoir is one of the tanks in the Kelani Ganga basin. Except for the drainage from its own catchment area, the tank is mainly fed by the Kalatuwawa Ela (Arumugam, 1969). The storage capacity is 3900 million gallons and the area of water spread is 454 acres at its full supply level (Arumugam, 1969).

The weir of the reservoir is 30 m high and 160 m long (Kotalawala, 2017). The greatest depth of the reservoir is 20 m (Kotalawala, 2017).
