The Department of Irrigation opened spill gates at several reservoirs in the Kirindi Oya and Walawe river basins on 12 November to release excess water following heavy rains.

At Lunugamwehera Reservoir, two spill gates were opened by 4 inches and four by 6 inches, releasing approximately 3,000 cubic feet per second into Kirindi Oya. Alikota Ara Reservoir's gates were also opened into the same river.

Over 1,500 cubic feet of water per second is being discharged into Maw Ara after spill gates at the Maw Ara Reservoir were opened.

Director of Irrigation Engineer H.M.P.S.D. Herath warned that downstream water levels could rise suddenly, urging low-lying residents along both river basins to monitor water levels and follow instructions from the department's Disaster Management Divisions.
