The Kanwar Taal or Kabar Taal Lake or Kabartal Wetland [2] located in Begusarai district of Bihar, India, is Asia's largest freshwater oxbow lake.[3]
It is approximately six times[4] the size of the Bharatpur Sanctuary. In November 2020, the Ministry of Environment, Forest and Climate Change (MoEFCC) declared it the first Ramsar site in Bihar.[5] There are a total of 85 Ramsar Sites in India till 2024.
Kanwar jheel, as it is locally called, is located 22 km north-west of Begusarai Town in Manjhaul. It is a residual oxbow lake, formed due to meandering of Burhi Gandak[6] river, a tributary of Ganga, in the geological past.[7] It covers 2,620 hectares of the Indo-Gangetic plains in the northern Bihar State. The Site is one of 18 wetlands within an extensive floodplain complex; it floods during the monsoon season to a depth of 1.5 metres. This absorption of floodwaters is a vital service in Bihar State where 70% of the land is vulnerable to inundation. During the dry season, areas of marshland dry out and are used for agriculture. Significant biodiversity is present, with 165 plant species and 394 animal species recorded, including 221 bird species. The Wetland is an important stopover along the Central Asian Flyway, with 58 migratory waterbirds using it to rest and refuel. It is also a valuable site for fish biodiversity with over 50 species documented. Five critically endangered species inhabit the site, including three vultures – the red-headed vulture (Sarcogyps calvus), white-rumped vulture (Gyps bengalensis) and Indian vulture (Gyps indicus) – and two waterbirds, the sociable lapwing (Vanellus gregarius) and Baer’s pochard (Aythya baeri). Major threats to the Site include water management activities such as drainage, water abstraction, damming and canalization.[8]
Ornithologist Salim Ali, mentioned about 60 migratory birds that come all the way from Central Asia in winter and recorded around 106 species of resident birds.[9][10] Since 2020 the lake has been designated as a protected Ramsar site.[1]
