Risk breakdown
- • Storage high at 93.0%
- • Only 0.70 m of freeboard left below FRL
- • Level 84.05 m is at or above the orange alert level of 83.75 m
Rate of rise(derived)
+0.03 m / 24 h
At the current rate, Red alert band in ~12 days (0.35 m to go)

Rule curve — seasonal operating target
No rule curve (seasonal guide curve) is published for Neyyar 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
Neyyar is at orange alert with storage steady at 94%, a water level of 84.1 m against the 84.75 m FRL, and all four spillway shutters open 10 cm, releasing 25.65 cumecs alongside drinking-water outflow. Recent rain of 21.1 mm and forecasts of 32.4 mm in 24 hours and 51.8 mm in 72 hours are maintaining pressure; the next alert level would be triggered if the water rises to the reservoir’s red-alert threshold, which is not provided here.

- Hydropower grid offset

CH₄ from flooded land × GWP-100 (27), age-adjusted
Western Ghats forest sink, 60% forest cover assumed

vs CEA grid 0.716 kg CO₂/kWh, 35% capacity factor
Net catchment balance: Not enough data/yr (forest + sediment sinks minus reservoir methane)
