No rule curve (seasonal guide curve) is published for Sholayar 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.
Sholayar is at no alert level, with storage at 86.39% (down from 86.9%) and water level at 809.396 m, 2.286 m below the 811.682 m FRL; there is no spill. Rainfall of 16.5 mm in the past 24 hours and forecasts of 21.6 mm in 24 hours and 54.4 mm in 72 hours are the main drivers, with flood risk at 38 and landslide risk at 16; the next alert would be triggered when the reservoir reaches its defined alert threshold, which is not provided.
Kerala Sholayar on the Chalakudy river adjoins the Tamil Nadu Sholayar reservoir and feeds a 54 MW powerhouse; its releases flow down to Poringalkuthu.
