Thiruvananthapuram, Oct 24 : Kerala Chief Minister Pinarayi Vijayan has drawn his Tamil Nadu counterpart M.K. Stalin's attention on the immediate need to send directions to the authorities concerned to draw maximum quantity of water from Mullaperiyar dam through the tunnel to Vaigai Dam in the latter state. In his letter, Vijayan requested Stalin to direct officials to gradually release this water downstream, and also intimate the Kerala government about the opening of the shutters 24 hours in advance to help them take precautionary measures for ensuring the safety of people living downstream in the state.
