Heavy rainfall in the high-range Idukki district of Kerala prompted authorities on October 25 to release water from a couple of minor dams where water had reached close to the red level.
The Idukki district administration said that permission was granted to release 500 cumex of water from the Pambla dam and raise two shutters of the Kallar dam by 10 cm each.
The administration said the permission was granted in view of heavy rainfall in the catchment area of the two dams and rise in their water storage levels.
It advised people living along the Periyar, Kallar and Chinnar rivers to be cautious and follow the safety directions issued by authorities.
The India Meteorological Department (IMD) on October 24 had issued a yellow alert in Idukki and three other districts of Kerala.
There were also reports of landslips in some parts of Kerala following heavy rain.
While more than an acre of agricultural land was lost in the landslips, no one was hurt and no houses were damaged, local authorities had said.
