Bhubaneswar, August 15 (LocalWire): The state Water Resources Department (WRD) has sounded a moderate flood alert in 11 districts even as 20 gates from the multi-purpose Hirakud dam were thrown open for the discharge of floodwater.
Today being a fool moon day, the discharge of floodwater from Mahanadi river system into the Bay of Bengal has not been fast and swift.
As the sea is unsteady due to the natural impact of the full moon, the steady discharge of river water into the sea will begin by Friday evening hours.
“Still, there is a cause of alarm, as the flood water discharged from Hirakud will take more than two days to reach Mundali barrage on the Mahanadi river system.
By the time the huge volume of water reaches the barrage, the discharge process of floodwater to sea would have picked up a steady pace,” WRD officials said.
As against 26.41 feet danger mark at Naraj, the flooded Mahanadi was flowing at 25.83 feet below the danger mark at 3 pm today.
Heavy rainfall in lower catchment areas of river Mahanadi over the past one week had led to the rise in the water level of the dam.
The water level at the Odisha’s largest multi-purpose dam at Hirkud dam, that helps controlling floods, caters to irrigation besides hydroelectricity production, stood at 622 ft at 3 pm today as against full reservoir capacity of 630 ft. Water inflow into the dam was 1,98,726 cusec and outflow 2,09,809 cusec by 3 pm today.
The WRD engineer-in-chief Akshaya Kumar Banarjee said that since the intensity of rain in the lower basin area of river Mahanadi had slowed down, the level of water in the state’s major river had stabilized, and there was no reason for people to panic.
“Besides the flood water that was released from Hirakud dam is being absorbed by tributaries and creeks connected to the river system,” he stated.
The department had estimated inflow of 10.50 lakh cusec of floodwater at Mundali barrage by 15 August.
“However, the flow of water is likely to be around 9.50 lakh cusec,” he said.
As per latest reports at 3 pm today, besides river Mahanadi and its tributaries Devi and Kushabhadra, rivers Brahmani, Baitarani, Burhabalanga Subarnrekha, Vansadhara, Rushikulya, Jalaka were also flowing below the danger level despite discharge of floodwater from 16 gates of the Hirakud dam.
The water level at the dam stood at 622 ft at 3 pm today as against full reservoir capacity of 630 ft. Water inflow into the dam was 1,98,726 cusec and outflow 2,09,809 cusec, he informed.
“The engineers of the water resources department on the downstream of river Mahanadi are inspecting the embankment zones susceptible to breach.
Sand-filled bags and bamboo poles are being installed at vulnerable spots to thwart possible breach of river embankment,” he added.
There is no major cause for worry for major flood inundating the State.
In all likelihood, the flood if it strikes will be on a moderate scale.
However, the office of Special Relief Commissioner has asked the administration of Bolangir, Subarnapur, Boudh, Angul, Nayagarh, Cuttack, Khordha, Jagatsinghpur, Puri, Kendrapada and Jajpur districts to be vigil and alert to face any exigencies due to flood.
