Thabbowa Reservoir releases 2,640 cusecs into Mee Oya

Newsfirst, Newswire, Ada Derana and Sri Lanka Mirror report that heavy rainfall has led to spill or sluice gates opening at several Sri Lankan reservoirs. Newsfirst says the Department of Irrigation reported reservoirs spilling across the country and that two gates at the Polgolla Mahaweli Dam were opened, with released water flowing toward the Victoria Reservoir.

Daily Mirror reports that eight spillway gates at Thabbowa Reservoir are releasing 2,640 cubic feet of water per second into Mee Oya, and urges residents downstream and along the river to remain vigilant. Sri Lanka Mirror separately reports that two Thabbowa gates, each opened by half a foot, were opened to manage rising water levels.

Sri Lanka Mirror reports that eight Deduru Oya Reservoir gates were opened by two feet each, releasing 10,400 cubic feet per second into Deduru Oya. It also reports six Rajanganaya gates opened at differing heights, with the reservoir initially releasing more than 3,800 cubic feet per second into Kala Oya. Hiru News reports six Rajanganaya spill gates are open.

Ada Derana reports that 16 Rajanganaya gates are to be opened, while its Sinhala-language report also gives a 16-gate figure. Hiru News’ Sinhala-language report says gates at both Rajanganaya and Thabbowa have opened. Sri Lanka Mirror says gate openings and release volumes may change with rainfall in catchment areas and inflows. It reports that residents near Deduru Oya, Kala Oya and other downstream areas were advised to stay alert, follow official updates and heed safety guidance.
