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 yellow alert, with storage rising from 60.23% to 64.36%; the level is 419.9 m against an FRL of 423.98 m, while 50.56 cumecs is being spilled with all crest gates fully open and sluice gates closed. The rise is driven by 94.6 mm of rain in the past 24 hours, though only 10.9 mm is forecast in the next 24 hours and 27.9 mm over 72 hours; the next alert would be triggered if the reservoir level reaches the specified higher-level threshold, which is not provided.

Estimate, not a measurement — built from IPCC 2019 Flooded Lands factors and public dam data. Kerala does not publish measured reservoir emissions. Credits shown are indicative, not registered. How this is calculated
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.
