Kerala: Idukki dam water level nears full level, orange alert issued


Idukki dam reservoir in Kerala is nearly full as incessant rains continue to lash the region. The water level in the dam is just nine feet short of the full level forcing the authorities to issue an ‘orange alert’. Water level in Idukki dam has touched 2395.26 feet whereas full reservoir level of the dam is 2404 feet.

The Kerala State Disaster Management Authority (KSDMA) said an orange alert does not mean that shutter operations would be done anytime now. The shutters would be opened only in daylight and after sufficient notice is given to the public and all stakeholders concerned, it said in a statement.

There was no need for the public to panic, KSDMA said. The final red alert would be issued when the water level touches 2399 feet, it said.The water level is related to the Mean Sea Level and catchment area.

Earlier, the Kerala government put the Army, Navy, Air Force and Coast Guard on alert to meet any eventuality in case water is released.

Kerala State Electricity Board sources said that when the level reaches 2,397 feet, there was a possibility of water being released on a trial basis for one or two hours. This was to find out if there were any obstruction and diversion on the route the water flows, they said.

A team of National Disaster Response Force has already been deployed in Ernakulam and Thrissur and another team wouldreach Idukki, Kerala Chief Minister Pinarayi Vijayan said in a Facebook post.

“Army, navy, airforce and coast guard have been asked to be on vigil. Two helicopters have been kept ready. There is no need to panic as of now. The State Disaster Management Authority will give timely directive in this regard,” he said.

“Coast Guard is also ready with small boats to evacuate people if water enters low-lying areas of Ernakulam,” the CM added.

People living downstream of the reservoir upto Lower Periyar area in Ernakulam district have been asked to be vigilant, he said.

The reservoir comprises three dams -Idukki, Cheruthoni and Kulamavu, built for the the Idukki Hydroelectric Project.

In the event of opening the sluice gates of Cheruthoni dam, the water would flow through Ernakulam from Idukki, before reaching the Arabian sea, Vijayan said.

According to KSDMA, restrictions have been imposed on tourists visiting some areas near the dam. The Idukki reservoir’s shutters were last opened in 1992. This is the first time it would attain full-level during the South West Monsoon period.

While Idukki dam is used to store water, the other two dams are meant to route water to the powerhouse.
