Bordoibam Bilmukh Wetland

Bordoibam Bilmukh Wetland is a large natural wetland and bird sanctuary located near Dhakuakhana on the border of Dhemaji and Lakhimpur districts in Assam. Formed after the 1950 Assam earthquake when the Subansiri River changed course, it covers about 11.25 sq km. Notified as a Bird Sanctuary in 1996, it is known for resident and migratory waterbirds, rich aquatic vegetation and scenic wetland landscape.

Visitors can expect a vast open wetland with shallow water, marshes, and grasslands surrounded by rural landscape. The area offers views of waterbirds, migratory ducks, storks and raptors, especially in winter. Visitors can explore earthen embankments, watchtowers and boating points, observe fishing activities, and experience a quiet natural environment with opportunities for birdwatching and photography during daylight hours.

The wetland was formed in 1950 when the Subansiri River changed its course following the great Assam earthquake of 1950, submerging the Bordoibam village area. The resulting beel (wetland) developed into a rich aquatic ecosystem and was declared as Bordoibam Bilmukh Bird Sanctuary in 1996 by the Government of Assam for conservation of avifauna.

The wetland supports local fishing and traditional livelihoods and is valued by surrounding communities for its natural resources. It is recognized as an important birding site in Assam and contributes to nature education and eco-tourism in the Dhakuakhana region.
