The Gandaki River, also known as the Kali Gandaki and the Gandak, is a tributary of the Ganges River. It is one of the major rivers of Nepal and is notable for the deep gorge through which it flows and for a large hydroelectric facility.
The Kali Gandaki rises in the Tibetan plateau north of the Himalayas in the Mustang District of Nepal, near the border with Tibet. The two headwaters of river, Nup Chhu and Shar Chhu ("West River" and "East River") meet near the town of Lo Manthang in upper Mustang. The river then flows southwest with the name of Mustang Khola. In Kagbeni a major tributory, Kak Khola, coming from Muktinath, meets Mustang Khola, and from there river is called the Kali Gandaki.
