Downstream exposure
The downstream reach and local body list for Cheruthoni 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 Cheruthoni 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.
Cheruthoni is the concrete gravity dam of the Idukki reservoir complex and carries the scheme's only spillway. Its five shutters were opened in August 2018 for the first time in 26 years during the Kerala floods.
