Thiruvananthapuram: Kerala State Electricity Board (KSEB) on Friday said that Banasura Sagar dam will have to be opened if heavy rains continue. The total capacity of the dam is 775.6 meters. Currently the water level in the dam has reached 771.2 meters.
If it reaches 773.9 meter, the excess rainwater will be released in a regulated manner. Last year, the severity of flood increased after excess water from Banasura Sagar dam was released.
Beechanahalli dam in Karnataka has been opened completely and it releases 1 lakh cusecs of water every second. This water from Beechanahalli dam should go through Banasura Sagar dam. If the heavy rain continues to pour down, the amount of water released should be increased. Otherwise, it will harm the safety of Banasura Sagar dam, said KSEB.
If the inflow of water to the Banasura Sagar dam remains unchanged or increases, the reservoir will be opened any time on Saturday after 8 am, added KSEB. However, officials said that bigger dams like Idukki, Idamalayar, Sholayar, Kakki and Pamba will take several days to reach its maximum capacity of storage and are not likely to be opened soon.
As the water inflow into Aruvikkara dam has increased, more amount of water will be released from it. At present, the shutter here has been opened at a height of 15 cm. It will be raised to a height of 35 cm. People who reside on the banks of Karamana river are also alerted of potential danger.
With heavy rains persisting, the state water department has opened a control room. Contact number: 0471 – 2324150.
