Sri Lanka is pockmarked with many irrigation dams, with its water resource distributed across nearly the entirety of the island for agricultural purposes via artificial canals and streams. Utilization of hydro resources for agricultural production dates back to the pre-Colonial era , with the current crop production now largely dependent on ...
The Samanala Dam (Sinhala: සමනලවැව වේල්ල) is a dam primarily used for hydroelectric power generation in Sri Lanka. Commissioned in 1992, the Samanalawewa Project ( Samanala Reservoir Project ) is the third-largest hydroelectric scheme in the country, producing 405 GWh of energy annually.
Similar most other dam's impacts on rivers around the world, the Upper Kotmale Dam will periodically stop the St. Clair's Falls, located 2.2 km (1.4 mi) downstream of the dam, and a further 2.9 km (1.8 mi) of the Kotmale River downstream of St. Clairs Falls, before the river is restored by water from the Devon River, the river forming the ...
The Kalu Ganga Dam is a large gravity dam, and the second vital component of the larger and more complex Moragahakanda — Kalu Ganga Project across the Kalu Ganga at Pallegama, in the Matale District of Sri Lanka. The Kalu Ganga is a tributary of the Amban Ganga which in turn is a tributary of the Mahaweli River, the
The Rantembe Dam (Sinhala: රංටැබේ වේල්ල) is a 52-megawatt hydroelectric gravity dam at Rantembe, in the Central Province of Sri Lanka. Construction of the dam began in January 1987, and was completed on schedule in April 1990.
The three large spillways of the dam. The Randenigala Dam is located 19 km (11.8 mi) downstream of the Victoria Dam, and 2.8 km (1.7 mi) upstream of the Rantembe Dam. Randenigala measures 94 m (308 ft) in height, 485 m (1,591 ft) in length, with a crest and base width of 10 m (33 ft) and 303 m (994 ft) respectively.
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]
The dam creates the Kukule Ganga Reservoir, which has a capacity and catchment area of 1,630,000 m 3 (58,000,000 cu ft) and 312 km 2 (120 sq mi) respectively. After passing through the dam and sand traps, water from the reservoir is fed into a 5.71 km (3.55 mi) long tunnel, which leads to the underground power station.
