Water level in Idukki dam touches 2,368.90 ft
No threat of opening the dam shutters
Water level in Idukki dam reached 2,368.90 ft on Sunday morning.
Compared to the water level of 2,333.76 ft on the same day the previous year, the reservoir had a better storage level, said an official of the Kerala State Electricity Board (KSEB). He said that as per the rule curve level fixed by the Central Water Commission (CWC) at 2,380.58 ft, a blue alert will be sounded at the level of 2,372.58 ft and the shutters of the dam would be opened only if the level reached the red alert level of 2,379 ft. At present, there was no threat of raising the shutters, he said.
The CWC fixed the new rule curve level to avoid a sudden opening of the dam shutters as in the case of 2018. It was fixed for releasing the water to reduce the risk of opening the shutters at the maximum water level.
The full storage level is 2,403 ft.
