Irrigation Department warns of minor floods as river water levels rise across island

Water levels in several major rivers have reached minor flood levels following heavy rainfall across Sri Lanka over the past 24 hours, the Department of Irrigation said on 12 November.
Chief Hydrology Management Engineer L. S. Sooriyabandara reported minor floods along the Attanagalu Oya at Gampaha and Doonamale, and the Gin River at Baddegama. Water levels in the Nilwala and Kalu rivers are also approaching minor flood levels.
Rainfall reached 100 to 120 millimetres in upper catchment areas of the Gin and Nilwala rivers. Locations along the Kalu River, lower Attanagalu Oya, and Kataragama recorded nearly 100 millimetres, while most other areas received 50 to 75 millimetres.
With further heavy rain expected today in the wet zone and six provinces, the department warned that reservoir spill gates may open, creating a risk that roads and low-lying areas could quickly inundate.
