Labugama Reservoir (Sinhala: ලබුගම 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 Wak Oya for water supply for domestic consumption in Colombo City (Arumugam, 1969). The reservoir along with the nearby Kalatuwawa Reservoir is maintained by the Colombo Municipal Council.
History
The Labugama weir was constructed by the British Colonial Government in 1882 (Kotalawala, 2017). The construction work of the tank was completed in 1886 (Arumugam, 1969).
The reservoir
Labugama 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 Wak Oya (Arumugam, 1969). The storage capacity is 1960 million gallons and the area of water spread is 205 acres at its full supply level (Arumugam, 1969).
The weir of the reservoir is 26.5 m high and 150 m long (Kotalawala, 2017). The greatest depth of the reservoir is 22.5 m (Kotalawala, 2017).
