Idukki (Ker) | The Mullaperiyar Dam's water level rose to 137.50 ft on Monday, prompting authorities to decide on releasing excess water through the spillway starting tomorrow, officials said here.

The Idukki District Disaster Management Authority, chaired by Collector Sheeba George, held a review in response to the rising water levels caused by unexpected and continuous rains in the catchment area.
