Site description This site includes the riverine tracts of the Brahmaputra River near its confluence with one of its tributaries, the Jhanji. In addition, there are some lakes and marshes such as Digholi, Misamari, Kawoimari and Laujan, which harbour avifauna. Situated 30 km northeast of Jorhat, the district headquarters, this wetland complex is an important site for waterbirds. The terrain is flat, being part of the floodplains of the Brahmaputra. During monsoon, the major part of this area is completely inundated.
