The Tamil Nadu government has urged Andhra Pradesh to stop construction activities of check dams across Kosasthalai river.
In his letter to the AP CM N Chandrababu Naidu, a copy of which was released to the media, TN chief minister Edappadi K Palaniswami said, “I wish to bring to your urgent notice an important issue relating to the action of the irrigation department of the government of Andhra Pradesh by commencing construction of a check dam across the river Kusa at Nelavayl Village, Karvet Nagar Mandal, Chittoor district, which is a sub-tributary of the inter-state river Kosasthalaiyar.”
Palaniswami said the Irrigation Department of Andhra Pradesh has commenced construction of a check dam across river Kusa at Nelavayl village in Chittoor District there. Kusa was a sub-tributary of inter-state Kosasthalaiyar river, he said.
“This unilateral action of the authorities in Andhra Pradesh has caused great alarm and apprehension amongst the farmers in Tamil Nadu. The Kusa river, a sub-tributary of Kosasthaliyar river, supports an ayacut of about 354.32 acres fed by the Veligaram tank (Thiruvallore district) in Tamil Nadu. Any intervention of the flow to this tank is of great concern to the farmers who depend on the waters of this tank,” he said.
“The government of Andhra Pradesh should have consulted and obtained prior consent of the lower riparian state of Tamil Nadu before commencing any new work across the river Kusa, or in any stream/channel taking off from it. This action of the authorities in Andhra Pradesh will affect the natural flow in the stream or channel taking off from it and would obstruct the flow to the Veligaram tank in Tamil Nadu,” he said.
Palaniswami added: “In these circumstances, the government of Tamil Nadu lodges its strong protest against the action of the government of Andhra Pradesh in having unilaterally commenced the work for the construction of a check dam.”
