Where does the Indus River have its source in China?

Explanation

The Indus River begins near Lake Manasarovar, located in the Tibetan region of China. This lake, also called Mapam Yumco, is the traditional source of the river, which starts in the Himalayas at an altitude of about 5,182 meters. The Indus River flows through Tibet, India, and Pakistan before emptying into the Arabian Sea. It is historically significant, lending its name to the Indus Valley Civilization, and its basin supports extensive agriculture. The river system is managed under the Indus Waters Treaty signed in 1960.
