No rule curve (seasonal guide curve) is published for Neyyar 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.
Neyyar is at orange alert with storage at 92%, down from 93%, and the water level at 83.94 m versus the 84.75 m FRL; it is spilling 3.24 cumecs while also supplying drinking water. Recent rain was 16.9 mm, with 11.1 mm forecast in 24 hours and 43.9 mm over 72 hours, so the next alert would be triggered if continued inflows push the level closer to the 84.75 m FRL; flood risk is 39 and landslide risk 15.
