Kerala is trapped by its promise to host Tamil Nadu’s Mullaperiyar dam for a millennium
A study should be done to asses the water needs to the service area and the long term averages of water use. Once it is done, water from the Mullaperiyar reservoir can be diverted to Tamil Nadu during the monsoon and stored in the existing or new storage facilities there.
Whether there should be a new dam or the existing dam is safe to store water for some more time can then be dispassionately assessed by independent experts.
