Rule curve — seasonal operating target

No rule curve (seasonal guide curve) is published for Maniyar (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.

AI analysis

Maniyar Barrage is at red alert, with storage rising sharply from 36% to 53% after 50.5 mm of rain; the water level is 31.6 m versus the 34.62 m FRL, and all five shutters are open 4.5 m despite zero recorded spill. With another 14.8 mm forecast in 24 hours and 36.8 mm over 72 hours, the next escalation would be triggered if the level continues toward the 34.62 m FRL or spill begins, especially given the flood-risk score of 52.

Environmental & carbon accounting

Insufficient data
Reservoir methane (gross)
Not enough data /yr

CH₄ from flooded land × GWP-100 (27), age-adjusted

Green carbon — catchment forest
Not enough data /yr

Western Ghats forest sink, 60% forest cover assumed

Blue carbon — sediment burial
Not enough data /yr

Hydropower grid offset
Not enough data /yr

vs CEA grid 0.716 kg CO₂/kWh, 35% capacity factor

Net catchment balance: Not enough data/yr (forest + sediment sinks minus reservoir methane)
