The Bowatenna Dam is a 100feet high gravity dam at Bowatenna, in Central Province of Sri Lanka. The dam was built in, and is used primarily for irrigation. A power station is also constructed 5800feet downstream, for hydroelectric power generation.[1] [2]
The dam creates the iconic Bowatenna Reservoir, measuring approximately 11800feet and 10500feet at its widest and longest latitude and longitude, respectively. The reservoir has an active capacity of 21000abbr=onNaNabbr=on and a maximum surface elevation of 800feet.
The dam consists of six spillways, measuring a combined width of 2220NaN0, or 160NaN0 each. The spillways combined has a maximum discharge capacity of 125000abbr=onNaNabbr=on.
After the completion of the Moragahakanda Dam, a percentage of water from the Bowatenna Reservoir would also be transferred to the new Moragahakanda Reservoir, to be located approximately 3miles away, via tunnel.[3]
The power station, located 5800feet downstream, consists of a single Fuji unit. The power station was commissioned in .[4]
