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.
Kallarkutty is at red alert with storage at 98.48%, up from 97.68%, and the water level at 456.4 m—just 0.19 m below the 456.59 m full reservoir level—despite a 30 cumec spill through gates 2 and 3 opened 15 cm. Recent rain of 29.7 mm and forecasts of 16 mm in 24 hours and 40.4 mm in 72 hours are driving inflows; reaching the full reservoir level or continued rapid storage rise would trigger the next emergency alert or increased gate releases.
