No rule curve (seasonal guide curve) is published for Poringalkuthu 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.
Poringalkuthu is at red alert, with storage rising from 54.09% to 56.93%; the water level is 419 m against an FRL of 423.98 m, and 177.08 cumecs is being spilled with all crest gates and Sluice Gate #1 fully open. The rise is being driven by 22.8 mm of rain in the past 24 hours, with another 18.8 mm forecast in 24 hours and 53.7 mm in 72 hours; the next alert would be triggered at the specified higher water-level or storage threshold, which was not provided.
Poringalkuthu on the Chalakudy river was Kerala's second major hydel station, commissioned in 1957, and is supported today by the downstream Poringalkuthu Left Bank extension.
