Bhubaneswar: Odisha government has decided to open sluice gates of Hirakud dam to release excess water from the reservoir following heavy rainfall in the upper catchments of Mahanadi river.
Briefing the media on Tuesday, Special Relief Commissioner (SRC) Pradeep Jena said as the depression will move in the west-north-west across north Chhattisgarh and Madhya Pradesh and weaken into a well-marked low-pressure area during next 48 hours, the Hirakud Dam authorities will open some sluice gates later in the day.
“At present the Hirakud reservoir is receiving about 1.95 lakh cusecs mostly from the Tel river. With Chhattisgarh already receiving heavy rainfall, the dam authorities will open the gates today and release about 5 to 6 lakh cusecs to bring down the water level of the dam. “If we will release this water through Mundali barrage within 24 hours, we will be able to manage the excess floodwater in the dam in the subsequent 24 hours as well as the flood in the lower catchments”, the SRC added.
