As Hirakud Dam Opens Two More Sluice Gates Minor Flood Anticipated In Mahanadi


Sambalpur: With the water level of the Hirakud reservoir in Sambalpur rising since Wednesday, the authorities have anticipated a minor flood in the Mahanadi basin.

Meanwhile, the authorities opened two more sluice gates on Saturday afternoon to release excess floodwaters.

Speaking to media persons, Engineer-in-Chief, Water Resources, Bijaya Kumar Mishra said that a minor flood is anticipated in the Mahanadi basin due to incessant rains in upper and lower catchment areas and the release of excess water from Hirakud Dam.

“Only the water level of Baitarani river at Akhuapada and Jalaka river at Mathani is flowing above the danger level. If there is a need of releasing excess water from the Hirakud dam reservoir, it may lead to minor flooding,” he said.

Notably, on July 18, the dam authorities had opened seven sluice gates to release the season’s first floodwater.

There are 64 sluice gates including 24 on the right and 40 on the left side of the dam to release flood water. Each sluice gate has the capacity to discharge 16,440 cusec of water when reservoir level, also termed as danger level, is 630 ft.

This apart, there are 34 crest gates, 13 on the right and 21 on left side, which have the potential to discharge 16,238 cusec of water.
