The lobby is trying to divert water from the east-flowing river to the Mangayaar stream — a dead stream in Tamil Nadu — via a 700-metre trench. Land grabbers based in Tamil Nadu have constructed a four-metre deep, three-metre wide trench along 80 metres.

Possible consequence of unscientific interlinkage
Govt officials have reported that the unscientific interlinking of Chinnar and Mangayaar would adversely affect the Muthuvan tribal settlement of Thayannankudy in the Chinnar Wildlife Sanctuary, not to speak of the drought situation in the downstream reaches due to the drying up of Chinnar along the 13-km stretch up to Koottar.
