Rajanganaya Reservoir

Rajanganaya Reservoir
Rajanganaya Wewa is a reservoir built across the Kala Oya river, at Rajanganaya, bordering the North Western and North Central provinces of Sri Lanka.

This is a newly built reservoir. However, on the Kadigala hill where the dam of Rajanganaya reservoir abuts into the rock are the ruins of ancient Maha Mangala Viharaya built on the bank of Gona Nadi (the ancient name used to identify the present Kala Oya river) by King Vankanasika Tissa [(109-112 A.D.) Arumugam, 1969]. Rock-cut flight of steps, Stupa mounds are found at this site (Arumugam, 1969).

The reservoir
The reservoir has been constructed by damming the Kala Oya river (Arumugam, 1969). The bund of the reservoir is about 1.62 km. long and the water is extending in an area of about 4,000 acres at its full supply level (Arumugam, 1969). It has one spill and two sluices (Arumugam, 1969).
