Ecology
The lake is predominantly eutrophic due to the inflow of sewage. The nutrients support the profuse growth of Water Hyacinth and Typha in the shallow zone. The habitat is favoured by many species of water birds including large waterbirds such as the Spot-billed Pelican, Eurasian Spoonbill, Shoveller, Pintail, Garganey, Little Grebe, Coot and Spot-billed Duck. The shallow zone supports sandpipers and other waders as well as Purple Moorhens, Purple Herons and Grey Herons.
In the late 1990s, an ecological experiment was conducted with the introduction of Neochetina bruchi and Neochetina eichhorniae weevils from Argentina to control the growth of water hyacinth.
