Dipor Bil is one of the most important bird sanctuaries in the Brahmaputra valley and serves as a major habitat for the Greater Adjutant Stork (Leptoptilos dubius).
It is the only Ramsar site located within the state of Assam.
The wetland acts as a critical biological filter for the industrial runoff and municipal discharge of Guwahati.
It is an extension of the Brahmaputra River, connected by the Khonajan channel.
The lake basin holds over 200 species of birds, including migratory visitors from as far as Siberia during winter.
Dipor Bil is a permanent freshwater lake in the Kamrup district of Assam, recognized as a Ramsar Site since 2002. It serves as a vital staging ground for migratory birds and is the only major storm-water storage basin for the Guwahati city drainage system. The lake acts as a natural floodplain for the Brahmaputra River, significantly impacting local hydrological cycles. It supports a diverse range of flora, including water hyacinth, wild rice, and aquatic grasses. The wetland provides a primary habitat for several endangered species, including the Greater Adjutant Stork. Conservation efforts are ongoing to mitigate the impact of urban waste disposal from the nearby municipal landfill. Local fishing communities rely on the wetland for livelihood and sustain traditional practices on its periphery. The ecosystem experiences significant seasonal variation in water volume, expanding greatly during the monsoon months.
The elevated viewing points along the southern periphery provide the best panoramic views of the water surface and birds.
Bring high-quality binoculars or a camera with a telephoto lens for bird watching.
Wear insect repellent to protect against mosquitoes prevalent in the wetland environment.
Stay on established paths to minimize disturbance to the fragile bird nesting grounds.
Avoid visiting during the peak monsoon season (July-August) when water levels can be unpredictable and access is often restricted.
Maintain silence to avoid startling wildlife; littering is strictly prohibited due to the site's status as a protected wetland.
