One spillway gate of the **Upper Kotmale Reservoir** was opened today (24) following
heavy rainfall in the reservoir’s catchment areas, according to reservoir engineers.

Heavy rain has been falling across the Upper Kotmale catchment since early this 
morning, causing the reservoir’s water level to rise.

Officials have warned that if the heavy rainfall continues, the **remaining spillway
gates could open automatically** as the water level increases.

Meanwhile, the **Disaster Management Centre (DMC)** has urged residents living along
both banks of the **Kotmale River downstream of the reservoir dam** to remain vigilant
and exercise caution.

Residents in the downstream areas are advised to closely monitor official updates
and take necessary precautions as rainfall and reservoir water levels continue to
change.
