Site description Kawar (Kabar) Lake Wildlife Sanctuary, also a Ramsar Site, is the largest freshwater lake in northern Bihar. It is a residual oxbow lake formed by the changing course of the River Gandak, a tributary of the Ganga. In years of average rainfall, the Kawar Lake joins with the nearby Nagri Lake, Bikrampur Chaur and Burhi Gandak, a tributary of the River Ganga, to form a lake of about 7,400 ha. By late summer, however, the water is confined to the deeper areas of only c. 200 to 300 ha. As the water level recedes, over 2,400 ha of the exposed mudflats are converted into paddy fields. There is a permanent island (Jaimanglagarh) of about 130 ha in the southeast corner of the lake. Kawar Lake experiences tropical monsoon climate typical of the middle Gangetic plain. The lake supports a rich and diverse aquatic flora. Submerged macrophytes include Hydrilla verticillata, Potamogeton crispus and Najas minor. Emergent macrophytes include Oryza sativa and Ipomea aquatica (Anon. 1993).
