Water discharge from the Mettur dam to Cauvery river rose to two lakh cusecs from Thursday morning, following heavy rains in catchment areas and copious inflow into the reservoir in the district.
Incessant rains in catchment areas and also water released from dams in neighbouring Karnataka resulted in heavy inflow into Mettur dam, official sources said, adding that the district administration sounded a flood alert to the people living on river banks and in low-lying areas.
The discharge was 1.40 lakh cusecs on Wednesday-Thursday midnight and touched 1.85 lakh late in the evening and heavy inflow resulted in release of two lakh cusecs this morning, which was 30,000 cusecs three days ago, official sources said.
The dam capacity is maintained at 120 ft, with water availability of 94 TMC, official sources said.
The highest discharge of surplus water from the dam was recorded at 2.17 lakh cusecs in 2018, they said.

Meanwhile, the Aliyar dam in Pollachi neighbouring Coimbatore was at 118 ft, as against its capacity of 120 ft, necessitating the release of surplus water. The administration sounded a flood alert to the people living on the river banks to move to safer places.
