Downstream exposure
The downstream reach and local body list for Kundala have not been transcribed from a District Disaster Management Plan yet, so none are shown.
District control room: 1077 / 04862-233111
No rule curve (seasonal guide curve) is published for Kundala 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.
Kundala is at no alert level, with storage at 62.09% (up from 61.44%) and water level at 1754.5 m, 4.19 m below the 1758.69 m FRL; all gates are closed with no spill or sluice discharge. The rise follows 33.8 mm of rain, while 78.5 mm is forecast over 72 hours, so the next alert would be triggered if the reservoir reaches the applicable alert-level threshold, which is not provided.
