YAMUNA RIVER

also called Jumna, river in Uttar Pradesh state, northern India, rising in the Himalayas near Jamnotri. It flows in a southerly direction through the Himalayan foothills and onto the northern Indian plain, along the Uttar PradeshHaryana state border. The Eastern and Western Yamuna canals are fed from the river at that point. The Yamuna then passes Delhi, where it feeds the Agra Canal. Near Mathura it turns southeastward and passes Agra, Firozabad, and Etawah. Below Etawah it receives a number of southern tributaries, the largest of which are the Chambal, the Sindh, the Betwa, and the Ken. Near Allahaba d, after a course of about 855 miles (1,376 km), the Yamuna joins the Ganges River; their confluence is a sacred place to Hindus. Traffic on the Yamuna is light. Above Agra it shrinks to a small stream in summer, partly because of the amount of water removed by the canals.
