  • 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. 


  • Kolleru Lake is the largest freshwater lake and is located in Andhra Pradesh. Kolleru is located between Krishna and Godavari delta and covers an area of 308 km². 

  • The lake serves as a natural flood-balancing reservoir for these two rivers. The lake is fed directly by water from the seasonal Budameru and Tammileru streams, and is connected to the Krishna and Godavari systems by over 68 inflowing drains and channels. 

  • It serves as a habitat for migratory birds. It supports the livelihood of fishermen and riparian population in the area. The lake was notified as a wildlife sanctuary in November 1999 under India's Wild Life (Protection) Act, 1972, and designated a wetland of international importance in November 2002 under the international Ramsar Convention.
