Kusheshwar Asthan Wetlands

Kusheshwar Asthan Wetlands is a large freshwater wetland complex in Kusheshwar Asthan block of Darbhanga district, Bihar, near the confluence of the Kosi and Kamla rivers. Spread over about 29 sq km, it comprises seasonal marshes, lakes and floodplains. Recognized as an Important Bird Area, it hosts resident and migratory waterbirds in winter. The wetlands lie adjacent to the revered Kusheshwar Asthan Shiva Temple, forming an ecologically and culturally significant landscape in Mithila region.

Visitors can expect an expansive low-lying wetland landscape of shallow lakes, marshes, chaurs and floodplains that fill during monsoon and retain water through winter. The area is known for large congregations of resident and migratory waterbirds, including ducks, geese, storks, cranes and waders. Views are open with agricultural fields and river channels surrounding the wetlands. Access is via earthen embankments and village tracks, with small boats used locally. The nearby Kusheshwar Asthan Mahadev Temple complex is often visited together with the wetlands.

The wetlands are formed by the floodplains of the Kosi and Kamla rivers and have long supported agriculture and fisheries in Mithila. The adjacent Kusheshwar Asthan Temple is traditionally believed to be an ancient Shiva shrine and has been a pilgrimage centre for centuries, giving the wetland complex its name and cultural association.

The wetlands are culturally linked to the Kusheshwar Asthan Mahadev Temple, an important Shaivite pilgrimage site in the Mithila region of Bihar. The area reflects the traditional rural and riverine culture of Darbhanga, with local festivals and religious gatherings at the temple often coinciding with the winter bird season.
