No rule curve (seasonal guide curve) is published for Pazhassi 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.
Pazhassi is at red alert with only 9% storage and a water level of 18.6 m versus the 29.26 m FRL, while releasing 2,101.61 cumecs through 15 open shutters. The situation is being driven by 35.6 mm of recent rain and 86.5 mm forecast over 72 hours, with flood risk 32 and landslide risk 24; the next escalation would be triggered if continued inflows require opening the final shutter or raising releases further.
The Pazhassi barrage across the Valapattanam river in Kannur is a shutter-controlled diversion structure with only a small live storage. During the monsoon its shutters are held open, so very large flows pass downstream even when the pond behind the barrage is nearly empty.
