The Water Resources Department has initiated an inquiry with the Andhra Pradesh authorities on the reported move to construct storage structures in rivers that feed many waterbodies, including Poondi reservoir in Tiruvallur district, which caters to the drinking water needs of Chennai.
According to sources in the Water Resources Department, construction of storage structures in the waterways in Andhra Pradesh border would affect inflow into the Poondi reservoir. It was learnt that the Andhra Pradesh government has planned to build a check dam or create a waterbody in the Lava river, which is one of the tributaries of Nagari river originating in Andhra Pradesh. Similarly, another storage structure is being proposed across the Nagari river in Andhra Pradesh limits, about 10 km away from the Tamil Nadu border.
