No rule curve (seasonal guide curve) is published for Madupetty (Mattupetty) 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.
An AI analysis for this reservoir will appear after the next scheduled briefing.
