Kolleru Lake Eluru

Address : Eluru

City/District : Eluru

State : Andhra Pradesh


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, 15 kilometers away from the city of Eluru. Kolleru is located between Krishna and Godavari deltas. Kolleru spans into two districts – Krishna and West Godavari.


Satellite images taken on 9 February 2001 by the Indian remote sensing satellite found that approximately 42% of the 245 km2 lake was occupied by aquaculture, while agriculture had encroached another 8.5%. The area under aquaculture consisted of 1050 fish ponds within the lake and 38 dried-up fish ponds, which together covered an area of 103 km2. The agricultural encroachments were mostly rice paddies. Surprisingly no clear water could be found in the satellite image. The rest of the lake is being diminished by water diversions or was infested with weeds like elephant grass and water hyacinth. Rich in flora and fauna, it attracts migratory birds from northern Asia and Eastern Europe between the months of October and March. During this season, the lake is visited by an estimated two million birds. The resident birds include grey pelicans, Asian open-bill (Anastomus oscitans), painted storks (Mycteria leucocephala), glossy ibises and white ibises.

Kolleru lake contains numerous fertile islets called lanka's, many of the small ones are submerged during floods. The origin of unusual depression which forms the bed of the lake is unknown, but it was possibly the results of an earthquake. Therefore, many ancient villages are precepted in the bed of the lake as a result of floods and earthquake.
