Kerala’s Idukki dam shutter opened after 26 years

Kerala government today opened one of the gates of Idukki dam after a gap of 26 years. The gate is called Cherutheni shutter.

It was opened following dangerous rise in water level in the dam. It had crossed 2398.80 ft level against full capacity of 2403 ft. The gate number three was lifted by 50 cm at 12.30 this afternoon in a trial run.

The decision follows various spells of heavy rains in Kerala. The heavy and incessant rains in Kerala have led to widespread flooding and death of at least 20 people. Kerala has been receiving heavy rainfall since June.

However, opening of one of the gates of Idukki dam will cause more flooding in the neighouring areas. An alert has been issued to warn the residents living in the vicinity of the Idukki dam and along the course of Periyar river. The lifting of the gate by 50 cm would release about 50 cubic metres of water every second.

Idukki Dam is the tallest arch dam in the country. It was in 1992 when the gates of the dam were last opened. Previously, the gates were opened in 1981 in a similar situation. In 1992, the water level had crossed the maximum height of the dam.
