Chembarambakkam Lake is located in Chengalpattu district, about
40 km from Chennai. The Adyar River originates from this
rainwater fed lake. The lake is one of the major sources of
drinking water in the city. The major threats are the growth of
water hyacinth and pollution from the surrounding catchment
area. The state government also proposed an industrial park in
the neighbouring area. Study was done by the scientists A.
Surendran and V.E. Nethaji Mariappan using remote sensing data.
In the beginning of the year, the hyacinth was concentrated only
on the central and southern part of the lake, the spread
increased by December. Of the 656.43 hectares of the lake, the
dense aquatic cover has taken over nearly 333 hectares. P. Raju,
president of Welfare Association of Chembarambakkam Lake
Drinking Water Consumers in Chennai City, files a Public
Interest Litigation against the state government. The government
proposed to build an industrial park near Chembarambakkam Lake.
