Malankara is the most stressed reservoir: red level, 96% storage, 41.7 m against 42 m FRL, and spilling 49.51 cumecs. Neyyar is orange at 92% with 3.24 cumecs spill; Kanjirappuzha is blue at 93% with 3.61 cumecs spill. Mangalam is orange at 85%. Rainfall is forecast across catchments: generally 2.6–21.6 mm in 24 hours and up to 69.5 mm over 72 hours, highest at Kundala. Over the next 24–48 hours, heavier-than-forecast rain could raise inflows, prompt wider shutter openings and increase downstream flood or slope-instability risk. Lighter rain and managed releases may stabilise or reduce levels. Follow official alerts near reservoirs and downstream rivers.
