No rule curve (seasonal guide curve) is published for Mangalam in a form this platform can verify, so none is shown. Where an operating curve is published — as for Idukki after the 2018 floods — it is plotted against actual storage instead of being estimated.
Mangalam is at red alert with storage at 81%, down from 87%, and the water level at 76.72 m against the 77.88 m FRL; all 6 spillway shutters are open 30 cm, releasing 26.89 cumecs. Recent rain of 19.8 mm and forecasts of 25.1 mm in 24 hours and 54.7 mm in 72 hours are sustaining inflows, with flood risk 37 and landslide risk 18; the next alert would be triggered if continued rainfall and inflows push the level toward the 77.88 m FRL despite spilling.
