The Sharda River is the downstream of Kali River that originates in the northern Uttarakhand state of India in the Great Himalayas on the eastern slopes of Nanda Devi massif, at an elevation of 3,600 m (11,800 ft) in the Pithoragarh district. It then flows between the Nepal and India border. Descending, it enters the Indo-Gangetic Plain at Brahmadev Mandi in Nepal, where it expands above the Sharda Barrage. From that point onward, it is known as the Sharda River. The river proceeds southeastward into India through northern Uttar Pradesh before merging with the Ghaghara River southwest of Bahraich, covering a distance of approximately 300 miles.
