Yamuna River

The Yamuna river is the second-largest tributary of the Ganges, originating from the Yamunotri Glacier at an elevation of 4,500 meters in the Lower Himalayas. It flows 1,376 kilometers through Uttarakhand, Haryana, Uttar Pradesh, and Delhi before merging with the Ganges at Prayagraj. The river has a drainage system of 366,223 square kilometers, accounting for 40.2% of the Ganges Basin. In Hinduism, the Yamuna is worshipped as a goddess and is believed to be the daughter of the sun god Surya and the sister of Yama, the god of death. The river supports nearly 57 million people, with more than 70% of Delhi's water supply coming from it. However, the river is severely polluted, with 80% of its pollution coming from a 22-kilometer stretch in Delhi.learn more on wikipedia
