Four shutters of the Idamalayar dam were opened on Thursday morning to release excess water from it, resulting in an increase in water level in Periyar river. Ernakulam district administration officials said relief camps have been opened in Choornikkara and Kombanad villages as it is anticipated that the release of water may cause inundation in these areas.
Kerala State Disaster Management Authority officials said there was no need for people living on the bank of river Periyar to panic.
The dam shutters were opened at 5 am, 6 am and 8 am. They were opened 1 metre each after the water level reached maximum storage capacity. The authority had yesterday sounded a red alert at Idamalayar dam after water level in the reservoir touched 168.20 metres.
