The Department of Irrigation has announced that spill gates of several reservoirs in the Kirindi Oya and Walawe River basins have been opened following rising water levels due to the prevailing rainy weather conditions.

Director of Irrigation (Water Management), Engineer H.M.P.S.D. Herath has urged residents living in low-lying areas along rivers and streams downstream of the reservoirs to remain vigilant over possible sudden increases in water levels.

According to the Irrigation Department, two spill gates of the Lunugamvehera Reservoir, located in the Kirindi Oya River basin, 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 Kirindi Oya.

Meanwhile, the spill gates of the Alikota Ara Reservoir, also located in the Kirindi Oya basin, have been opened, releasing additional water into the river.

The Department further stated that the Mau Ara Reservoir is also spilling, with more than 1,500 cubic feet of water per second being released into Mau Ara.

Authorities warned that the release of excess water from these reservoirs could result in sudden changes in water levels in downstream areas of the Kirindi Oya and Walawe River basins.

Residents living near the Walawe River, particularly in areas downstream of reservoirs, have also been advised to remain alert to rising water levels.

The Irrigation Department has urged the public to closely monitor river conditions and follow announcements and safety instructions issued by its Disaster Management Divisions regarding spill gate operations and changes in water levels. (Newswire)
