Kolleru Lake. 19/08/02. Andhra Pradesh. 90,100 ha. 16°37'N 081°12'E. Wildlife Sanctuary. A natural eutrophic lake, situated between the two major river basins of the Godavari and the Krishna, fed by two seasonal rivers and a number of drains and channels, which functions as a natural flood balancing reservoir between the deltas of the two rivers. It provides habitat for a number of resident and migratory birds, including declining numbers of the vulnerable Grey Pelican (Pelecanus philippensis), and sustains both culture and capture fisheries, agriculture and related occupations of the people in the area. Damage and losses due to flooding in monsoon seasons and partial drying out during summers, the results of inadequate management planning and action, are seen as areas for improvement. WWF-India has been of great assistance in preparing the site's designation. Ramsar site no. 1209. Most recent RIS information: 2002.
