Mahakali River

The Sharda River, also called Kali River and Mahakali River, originates at Kalapani in the Himalayas at an elevation of 3,600 m in the Pithoragarh district in Uttarakhand, India. It flows along Nepal's western border with India and has a basin area of 14,871 km2. It joins Ghaghra River, a tributary of the Ganges. It takes the name Kali River from the union of the two streams at Gunji as it flows through the hills. After Brahmadev Mandi near Tanakpur, it enters the Terai plains, where it is called Sharda River.It offers potential for hydroelectric power generation. The river is also proposed as source for one of the many projects in the Himalayan component of the Indian Rivers Inter-link project.
