The Department of Irrigation confirmed today, September 22, 2026, that water levels across the Deduru Oya reservoir and its principal tributaries in the North Western Province remain within normal operational safety thresholds.

Hydrological monitoring at the Moragaswewa and Chilaw river stations indicated that steady monsoonal runoff from intermediate catchment areas has not triggered flood risks. Irrigation engineers stated that spillway gates remain managed under automated regulation protocols, ensuring uninterrupted water reserves for downstream paddy cultivation while maintaining full flood-buffer capacities across regional agricultural schemes.
