One sluice gate of the Upper Kotmale Reservoir has been opened due to intense rainfall in its catchment areas, according to the Nuwara Eliya District Disaster Management Centre.

The gate was opened early this morning (20), and authorities warned that further rain could trigger the automatic opening of other sluice gates.

Residents living along the banks of Kotmale Oya have been advised to remain vigilant due to the potential risk of rising water levels.

Meanwhile, the heavy showers have also caused significant increases in the water flow at St. Clair and Devon waterfalls.
