No rule curve (seasonal guide curve) is published for Bhoothathankettu (Barrage) 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.
Bhoothathankettu regulates the combined flow of the Periyar and Idamalayar for the Periyar Valley Irrigation Project in Ernakulam district.
