The River Landscape

A Living Stretch of the Ganga

The sanctuary occupies a stretch of the Ganga near Bhagalpur, Bihar, running approximately from Sultanganj in the west to Kahalgaon in the east. Within this stretch, the river's channels, sandbanks, backwaters and confluence points create the varied riverine habitat that dolphins, gharials, otters, turtles and water birds depend on.

River geography in this stretch changes with the seasons — flow, depth and sandbank formation shift between the monsoon and drier months, which in turn shapes wildlife movement and the visitor experience through the year.

Detailed topographic and hydrological data are managed by the Forest Department and will be published here as official records become available.
