Solution:
The Yamuna rises from the Yamunotri glacier near Uttarakhand.It is the second-largest tributary of the Ganges and the longest of its tributaries in India. Like Ganga, Yamuna is one of the sacred rivers at its intersection with Ganga at Allahabad. It flows through Uttar Pradesh, Uttarakhand, and Haryana. Recently, the Yamuna river was claimed dead since it does not have water once it leaves Delhi. The Taj Mahal is on the banks of the Yamuna river. This drying up of Yamuna can adversely affect aquatic life and the monument.
