No rule curve (seasonal guide curve) is published for Malankara 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.
Malankara is at red alert with storage at 87%, down from 91%, and the water level at 40.82 m against the 42 m FRL; five of six spillway shutters are open 50 cm, releasing 149.83 cumecs, while water is also being released for drinking. The situation is driven by 69 mm of rain in the past 24 hours and forecasts of 26.8 mm in 24 hours and 73.3 mm in 72 hours, with flood risk at 46 and landslide risk at 36; no numerical trigger for the next alert level was provided.
