Deepor Beel. 19/08/02. Assam. 4,000 ha. 26°08'N 091°39'E. Sanctuary. A permanent freshwater lake in a former channel of the Brahmaputra river, of great biological importance and also essential as the only major storm water storage basin for the city of Guwahati. The beel is a staging site on migratory flyways and some of the largest concentrations of aquatic birds in Assam can be seen, especially in winter. Some globally threatened birds are supported, including Spotbilled Pelican (Pelicanus philippensis), Lesser and Greater Adjutant Stork (Leptoptilos javanicus and dubius), and Baer's Pochard (Aythya baeri). The 50 fish species present provide livelihoods for a number of surrounding villages, and nymphaea nuts and flowers, as well as ornamental fish, medicinal plants, and seeds of the Giant water lily Euryale ferox provide major revenue sources in local markets; orchids of commercial value are found in the neighboring forest. Potential threats include over-fishing and hunting pressure upon waterbirds, pollution from pesticides and fertilizers, and infestation by water hyacinth Eichhornia crassipes. A proposal to create a sewage canal from the city directly to the beel is considered to be disastrous in its potential effects. Ramsar site no. 1207. Most recent RIS information: 2002.
