Rivers in Bihar: Since Bihar's economy is entirely dependent on agriculture, the Rivers in Bihar are vital to the state's structure. This state is blessed with a large number of seasonal and permanent river locations. These are the state's surface water sources and there is water in certain alluvial state tracts in the north and south all year round.
The state is split between two uneven sections by the Ganga River. Additionally, the Rivers of Bihar are separated into two groups based on where they are located: the South and North Bihar Rivers.
