Mettur Dam water level at 81.69 feet, far below full capacity

The water level at Tamil Nadu’s Mettur Dam was reported at 81.69 feet on Wednesday, far below its full‑capacity mark of 120 feet.^[1][2]

The shortfall matters because the reservoir supplies water for millions of acres of paddy fields and other crops; a lower level threatens the upcoming Kuruvai sowing season and could force farmers to seek alternative sources.[^]

Inflow to the dam measured 191 cubic feet per second, while discharge was set at 1,500 cusecs to meet downstream needs.^[3][4] The gap between inflow and outflow underscores the limited replenishment of the storage.

Earlier reports from The Hindu gave differing readings – 66 feet on one occasion,^[5] 65.62 feet on another,^[6] 53.420 feet in a separate update,^[7] and 60.54 feet in a later bulletin.^[8] The range of 53 to 82 feet reflects fluctuating conditions and highlights the uncertainty surrounding the dam’s exact status.

Because the reservoir is well under its full level, authorities may delay water releases for non‑essential uses and prioritize irrigation, potentially impacting crop yields and rural livelihoods. The situation also raises concerns about water security in the broader region, especially if monsoon rains remain below average.

What this means: With the Mettur Dam operating at roughly two‑thirds of its capacity, Tamil Nadu’s agricultural sector faces a tighter water budget for the critical planting season. The disparity in reported levels signals a need for more consistent monitoring and transparent communication to help farmers and policymakers plan effectively.
