No rule curve (seasonal guide curve) is published for Kallada (Parappar) 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.
Kallada (Parappar) is currently at no alert level, with 55% storage and a water level of 105.15 m against the 115.82 m FRL; spill is 0 cumecs. Recent rain was 4.1 mm, with 14.6 mm forecast in 24 hours and 21.4 mm over 72 hours, contributing to a moderate flood-risk score of 47; the next alert would be triggered if the level rises to the listed threshold of 110.44 m.
