Two Victoria Reservoir spill gates open automatically

Two spill gates of the Victoria Reservoir opened automatically through the automated system on Friday afternoon, after the water level in the upper catchment areas of the Mahaweli River rose suddenly following heavy rain in the central hill country.

The automatic opening followed days of heavy rainfall across the central highlands, which pushed water levels in major reservoirs close to capacity.

Gates 1 and 2 were opened to 0.701 metres and 0.707 metres respectively; 159 cubic metres of water per second are currently being released from the reservoir into the Mahaweli River. Gates 3 to 8 remain closed. As the reservoir approaches maximum capacity, the outflow could increase further if rain continues; officials have asked people in downstream areas to pay attention to warnings.

The Victoria Reservoir, on the Mahaweli River, is one of the country's largest reservoirs and a major source of hydroelectric power. Officials said the reservoir's level is being monitored around the clock and further gate operations will be announced as needed. Residents along the river were advised to stay away from banks and low crossings until conditions stabilise.
