Victoria Randenigala Rantambe Reservoirs

The Victoria, Randenigala, and Rantambe (VRR) reservoirs were constructed during the late 1980’s under the Accelerated Mahaweli Development Programme, to meet the energy needs of the country, and also to provide irrigation water to the dry zone. In order to protect the upper catchment of the Mahaweli Ganga, the surrounding land area of these reservoirs was declared as a sanctuary in 1987. In addition to these major reservoirs, there are many small artificial and natural water bodies located within the sanctuary.

Wahalkada Wewa is one of the largest ancient irrigation tanks, which was built approximately 1,500 years ago during the time of King Mahasen. It was restored in 1973 by the Irrigation Department for the irrigation of paddy cultivation areas and other field crops such as onions, soya beans and groundnut.
