Thiruvananthapuram: In view of a probable flood havoc, the Central Water Commission (CWC) lowered the permitted water level in four major dams in the state. The water level in Idukki, Kakki, Banasura Sagar and Idamalayar dams under the control of Kerala State Electricity Board (KSEB) was revised.
The CWC fixed a lower water level than the one determined by the KSEB on various dates. Even if rainfall occurred or not, the water level in the dams should be maintained at the limit decided by the CWC. The KSEB approved the control line determined by the CWC.
If the water level exceeds, the dams should be opened earlier than usual or water level should be lowered by increasing power production. The CWC approved a very lower level than the one fixed by the KSEB in August when heavy rain was experienced in the state. The CWC is the authority to take final decision regarding the maintenance of dams.
The water level is lowered considering the flood havoc that occurred in August 2018. The flood intensified then as the filled dams had to be opened all at a time. Idukki dam was opened after 26 years on August 9, 2018, when the water level reached 2398.8 feet. But as per the CWC control line, water level should reach only 2383.53 feet on August 10 from now on. This is 15 feet lower than the earlier levels.
The water level in Idukki dam should be at 2373 feet on June 10 and it should be maintained till June 30. Though KSEB requested to increase the level after June 20, the CWC did not allow. Also the CWC decided the water level in Idamalayar dam on August 10 as 163 meter. In Kakki dam, the water level should be at 975.36 metre on June 10 as directed by the CWC. KSEB chairman N S Pillai said that the new guideline gives priority to flood control.
