Kolleru Lake
Summary
Kolleru Lake is one of the largest freshwater lakes in India located in state of Andhra Pradesh and forms the largest shallow freshwater lake in Asia (with 245 km2 of lake area and 302 km2 of total Ramsar designated wetland), 15 kilometers away from the Eluru and 65 km from Rajamahendravaram, it is located between Krishna and Godavari deltas. Kolleru Lake is located in Eluru district. The lake is fed directly by water from the seasonal Budameru and Tammileru streams, and is connected to the Krishna and Godavari irrigation systems by over 67 major and minor irrigation canals. This lake is a major tourist attraction. Many birds migrate here in winter, such as Siberian crane, ibis, and painted storks. The lake was an important habitat for an estimated 20 million resident and migratory birds, including the grey or spot-billed pelican (Pelecanus philippensis). The lake was declared as a wildlife sanctuary in November 1999 under India's Wildlife Protection Act of 1972, and designated a wetland of international importance in November 2002 under the international Ramsar Convention. The wildlife sanctuary covers an area of 308 km2.

Thousands of fish tanks were dug up, effectively converting the lake into a mere drain. This has great impact in terms of pollution, leading to difficulty in getting drinking water for the local people. This is in addition to the loss of ecological diversity and intrusion of sea water into the land masses and its fallout in terms of adverse influence on the rainfall pattern in this region. This imbalance has an adverse effect on the thousands of acres of crops in the upper reaches of the sanctuary, in view of the stoppage of water flow into the sea because of obstruction by the bunds of the fish tanks that have appeared illegally.
