Rule curve — seasonal operating target
No rule curve (seasonal guide curve) is published for Kallarkutty 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
Kallarkutty has no current alert, with storage at 72.07%, up from 64.03%, and the water level at 453.7 m versus the 456.25 m FRL; all five gates are closed and spill is 0 cumecs. The rise is being driven by 6.7 mm of recent rain, with 29.3 mm forecast in 24 hours and 40.4 mm in 72 hours; the next alert would be triggered if further inflows raise the reservoir to its prescribed alert-level threshold, which is not provided.
