The Department of Irrigation has warned residents living in low-lying areas along the Kirindi Oya and Walawe River basins to remain vigilant as water levels in several reservoirs have risen due to heavy rainfall.
The Department said spill gates of several reservoirs have been opened to release excess water.
At the Lunugamvehera Reservoir in the Kirindi Oya River Basin, two spill gates have been opened by four inches each, while another four gates have been opened by six inches each.
As a result, approximately 3,000 cubic feet of water per second is being released into the Kirindi Oya.
Spill gates at the Alikota Ara Reservoir have also been opened, with the additional water flowing into the Kirindi Oya.
