Kanwar Jheel is the largest in a series of 18 wetlands spread across the Ganges flood plains in India’s north Bihar. For generations, these wetlands have been the mainstay for this densely populated region, enabling families to farm the fertile soil and fish in nutrient-rich waters.
During the monsoon, when the River Burhi Gandak - a Ganges tributary - overflows its banks, the wetlands absorb the runoff, protecting this extremely flood-prone region. When the rains are over, the water shrinks to one tenth the size, exposing marshes and grasslands that create a mosaic of habitats for a wide variety of flora and fauna.
In winter, over 60 species of duck and waterfowl visit these wetlands on their annual migration routes along the Central Asian Flyway.
