Rule curve — seasonal operating target

No rule curve (seasonal guide curve) is published for Ponmudi 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

Ponmudi is at yellow alert, with storage rising from 59.64% to 59.98% and the water level at 698.95 m, just 1.05 m below the 700 m FRL; all gates remain closed with no spill. The rise is being driven by 28.6 mm of recent rain, with another 29.7 mm forecast in 24 hours and 46.5 mm over 72 hours; the next alert level would be triggered if the reservoir’s specified orange-level threshold is reached, but that threshold was not provided.
