KOLLERU LAKE ,VIJAYWADA ,ANDHRA PRADESH

• Thousands of fish tanks were dug up inside the wetland converting the lake into a mere drain. Apart from this the farmers had converted the land use pattern of the lake. 

                                   

• This had a lot of impact in terms of pollution leading to even difficulty in getting drinking water for the local people. The total area of the lake converted to aquaculture ponds accounts for 99.73km2 in 2004in comparison to 29.95km2 in 1967. 

                        

• The area under agricultural practice in the wetland also increased from 8.40 km2 in 1967 to 16.62km2 in 2004. Sewage inflow from the towns of Eluru, Gudivada and even Vijayawada and industrial effluents, pesticides and fertilizers from the Krishna-Godavari delta region contaminate the lake. 

                         

• Eleven major industries release about 7.2 million litres of effluents into the lake every day.
