Samanalawewa is located in the Uda Walawe Basin. It is located at the confluence of the Walawe River and Belihuloya Dam, at an elevation of 400 m (1,300 ft) above sea level, close to the town of Balangoda and 160 km from the capital Colombo. Samanala Wewa is primarily used for hydropower generation in Sri Lanka. The Samanalawewa project, authorized in 1992, is the second-largest hydropower project in the country, generating 405 GWh of energy per year. It was built with financial assistance from Japan and the United Kingdom. This caused a great deal of controversy due to a large water leak on the south bank.
Despite the leak, power generation continues as planned, and water from the leak supplies about two-thirds of the reservoir's target for agriculture in the downstream areas.
At present, special permission is required to visit this Samanala Wewa project. Photography is prohibited for security reasons. But the beauty of nature can be seen from the other side of the lake. Surrounded by mountains, the lake offers a spectacular view of beauty from afar. And the sluice gates are clearly visible. The sluice gates have been opened only twice since the tank was filled.
