Tamil Nadu objects to Kerala diverting excess water from Siruvani dam

Following the Tamil Nadu government’s objection to Kerala withdrawing water over and above its share from the Siruvani dam, the latter has stopped withdrawal from the check dam at Attapadi. As per the Parambikulam-Aliyar project agreement, Kerala is allowed to withdraw five cusecs from the Siruvani dam. The Kerala government had earlier requested Tamil Nadu to immediately release 400 cusecs of water to save standing paddy crops which the latter refused. Kerala’s move to withdraw excess water is seen as an arm-twisting tactic to obtain more water from the Aliyar reservoir.
