Yamuna << YUH muh nuh >> River, in northern India, forms one of the most important branches of the Ganges River. The Yamuna, which is sometimes called the River Jumna << JUM nuh >>, rises in the Himalaya and flows southeastward for almost 900 miles (1,400 kilometers). It empties into the Ganges at the city of Allahabad. Two canals, one leading west and one leading east, irrigate about 12,000 square miles (31,100 square kilometers) of farmland in the river valley. Much of the river, particularly in and around New Delhi, is badly polluted by sewage and other waste material. Cleanup efforts have had little success.
