The Bowatenna Dam is a 100 ft (30 m) high gravity dam at Bowatenna, in Central Province of Sri Lanka. The dam was built in June 1981 , and is used primarily for irrigation . A 40 MW power station is also constructed 5,800 ft (1,800 m) downstream, for hydroelectric power generation.
The Navet Dam is one of the major reservoirs supplying potable water in Trinidad and Tobago. The dam was completed in 1962 and expanded in 1966 and 1976. It supplies Tabaquite, Brasso, Williamsville, Gasparillo, San Fernando, Debe, Penal, Princes Town, Rio Claro, South Oropouche, La Brea Moruga, New Grant, Plaisance Park, La Romaine and Fyzabad.
The Broadlands Dam (also known as the Broadlands Hydropower Project by the developers) is a 35 MW run-of-the-river hydroelectric complex currently under construction in Kitulgala, Sri Lanka. The project is expected to be completed in 2020, and will consist of two dams, and a power station downstream.
Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for hydroelectric power generation. Hydroelectric dams, including small hydros, account for nearly half of the installed power capacity of Sri Lanka. Sri Lanka is pockmarked with many irrigation dams, with its water resource ...
The maiden waters of the dam was released in July 2018. [2] The larger combined project involved the construction of the Kalu Ganga Dam and Reservoir, along with the separate Moragahakanda Dam and Reservoir, for irrigation and power generation purposes. Both these sites were going to be located approximately 10 km (6.2 mi) apart. [3]
The dam creates the Dyraaba Reservoir (DR) which has a gross storage of 970,135 m 3 (34,260,000 cu ft) and active storage of 600,000 m 3 (21,000,000 cu ft). Water from the reservoir is channelled through a 15,290 m (50,160 ft) long circular pressurised-flow headrace tunnel measuring 4.25 m (13.94 ft) in diameter, which has a discharge capacity ...
The dam creates the relatively small Rantembe Reservoir, which has a catchment area of 3,118 km 2 (1,204 sq mi), and a total capacity of 21,000,000 m 3 (740,000,000 cu ft). Water from the reservoir is channelled through the dam through a steel penstock to power the two 26- megawatt turbines .
The Nilambe Dam is a small hydroelectric dam build across the Nilambe River, measuring approximately 70 m (230 ft) in length. Water from the Nilambe Dam is transferred to the 3.2-megawatt Nilambe Power Station through a 2.8 km (1.7 mi) penstock. The power station consists of two 1.6 MW generating units, which were commissioned in July 1988. [1] [2]
