The Navy has put on alert its Southern Naval Command in view of the rising water level in Periyar river in Kerala and a possible inundation of parts of Wellingdon Island, surrounded by the backwaters of Kochi.
A defence spokesperson said the Navy has made preparations to meet any situation arising out of the possible inundation of the island, said to be the largest artificial island in the country, following the opening of shutters of three dams of Cheruthoni, Idamalayar and Kakki.
"We will take all necessary steps to ensure that important installations in the island are not affected," the spokesman told.
The Wellingdon Island, part of Kochi city, houses strategic facilities, including the Southern Naval Command and Cochin Port Trust.
The water level will rise in downstream districts with the released excess water from the dams reaching there.
Areas in Kuttanad Taluk are likely to be affected, sources said.
