Rule curve — seasonal operating target
No rule curve (seasonal guide curve) is published for Sholayar 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.

AI analysis
Sholayar is at 88.79% storage, up slightly from 88.45%, with the water level at 809.823 m—1.859 m below the 811.682 m FRL—and no spill. Light recent rain of 1.4 mm and forecasts of 16.9 mm in 24 hours and 45.6 mm over 72 hours may drive further rises; the next alert would be triggered when the reservoir reaches its designated alert-level threshold, which is not provided.
