The downstream reach and local body list for Mangalam have not been transcribed from a District Disaster Management Plan yet, so none are shown.

No rule curve (seasonal guide curve) is published for Mangalam 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.
Mangalam is at orange alert with storage steady at 85%, water level 76.98 m—0.90 m below the 77.88 m FRL—and one of six spillway shutters open by 1 cm, releasing 1.36 cumecs. Recent rain of 14.1 mm and forecasts of 12.6 mm in 24 hours and 35.5 mm in 72 hours are sustaining inflows; the next alert level would be triggered if continued rainfall raises the reservoir to its red-alert threshold, which is not provided.
