The Ganges is a river that flows through India and Bangladesh and is considered to be a trans-boundary river of Asia.

Every year, millions of Hindus take a dip in the Ganga river as it is believed to cleanse oneself of all sins.

The river is also home to several species of rare and endangered animals

such as the Gangetic dolphin and the Ganga river turtle.

In recent years, the Ganga river has been severely polluted due to the discharge of industrial and domestic waste into it.

The river has its origins in the Himalayas, and it is considered to be sacred by Hindus. 

The important tributaries of Ganga are: the Yamuna, the Ramaganga, the Gomti, the Ghagra, the Son, the Gandak, the Burhi Gandak, the Kosi, and the Mahananda.
