Sambalpur: The water level of Hirakud reservoir, Odisha’s lifeline over Mahanadi River is decreasing due to inadequate rainfall.
As per reports, the water level at the dam was at 599.33 feet as on July 21 this year compared to 607.42 feet on July 21 in the previously year.
The flow of water into the reservoir was only 2,965 cusec and the outflow was 17,856 cusec through canals, power channel besides water for industries.
The declining water level at the reservoir may affect the hydroelectric power generation in Odisha, sources said.
