South India reservoir water levels and Cauvery sharing

Overview

By late August, continuous releases from Karnataka’s Kabini and Krishnarajasagar (KRS) dams caused water inflow at Hogenakkal to reach 12,000 cusecs. Following these inflows, the Tamil Nadu government announced that water from the Mettur Dam will be released to irrigate the Cauvery Delta districts.

On August 25, officials confirmed that Chief Minister C Joseph Vijay is expected to officially open the sluice gates on September 1, 2026, to begin irrigation in the Cauvery Delta. This decision follows a significant delay from the traditional June 12 release date, which was missed due to low reservoir levels and insufficient inflows from Karnataka. This delay has reportedly impacted Kuruvai paddy cultivation, with the area under this crop decreasing by approximately 42,000 hectares.

Water Resources Minister N Anand stated that the release is planned for a 45-day period, though the exact schedule remains dependent on storage levels and incoming inflows. As of late August, the Mettur Dam’s water level was approaching the 90-foot mark, a critical threshold for starting irrigation operations. While low storage previously made continuous irrigation unfeasible, the government noted that essential drinking water supplies have been maintained.
