The Kali Gandaki or Gandaki River is one of the real streams of Nepal and a left bank tributary of the Ganges in India. It is likewise called Krishna Gandaki in Nepal. In Nepal the waterway is eminent for its profound chasm through the Himalayas and its colossal hydroelectric potential. It has an aggregate catchment territory of 46,300 square kilometers (17,900 sq mi), a large portion of it in Nepal. The bowl likewise contains three of the world's 14 mountains more than 8,000 meters (26,000 ft), Dhaulagiri, Manaslu and Annapurna I. Dhaulagiri is the most elevated purpose of the Gandaki bowl. It lies between the comparable Kosi framework toward the east and the Karnali framework toward the west.
The Kali Gandaki stream source is at the fringe with Tibet at a height of 6,268 meters (20,564 ft) at the Nhubine Himal Glacier in the Mustang locale of Nepal.
The headwaters stream on a few maps is named the Chhuama Khola and afterward, nearing Lo Manthang, the Nhichung Khola or Choro Khola. The Kali Gandaki then streams southwest (with the name of Mustang Khola on old, obsolete maps) through a sheer-sided, profound gully before augmenting at the steel footbridge at Chele, where a portion of its stream pipes through a stone passage, and starting here the now wide waterway is known as the Kali Gandaki on all maps. In Kagbeni a noteworthy tributary named Johng Khola, Kak Khola or Krishnaa plummets from Muktinath.
The stream then streams southward through a precarious chasm known as the Kali Gandaki Gorge, or Andha Galchi, between the mountains Dhaulagiri, rise 8,167 meters (26,795 ft) toward the west and Annapurna I, height 8,091 meters (26,545 ft) toward the east. In the event that one measures the profundity of a gully by the distinction between the stream stature and the statures of the most elevated crests on either side, this crevasse is the world's most profound. The part of the waterway specifically in the middle of Dhaulagiri and Annapurna I, 7 kilometers (4 mi) downstream from Tukuche), is at a height of 2,520 meters (8,270 ft), which is 5,571 meters (18,278 ft) lower than Annapurna I. The waterway is more established than the Himalayas. As tectonic movement constrains the mountains higher, the stream has sliced through the elevate.
South of the canyon, the waterway is joined by Rahughat Khola at Galeshwor, Myagdi Khola at Beni, Modi Khola close Kushma and Badigaad at Rudrabeni above Ridi Bazaar. The stream then swings east to keep running along the northern edge of the Mahabharat Range. The biggest hydroelectricity venture in Nepal is situated along this stretch of the stream. Turning south again and getting through the Mahabharats, Kali Gandaki is then joined by a noteworthy tributary, the Trishuli, at Devighat, then by the East Rapti River depleting the Inner Terai valley known as Chitwan. The Gandaki then crosses the furthest foothills of the Himalayas—Sivalik Hills—into the Terai fields of Nepal. From Devighat, the waterway streams southwest of Gaindakot town. The stream later bends back towards the southeast as it enters India where it is known as the Gandak.
Beneath Gaindakot the waterway is known as the Narayani or Sapt Gandaki (Seven Gandakis), for seven tributaries ascending in the Himalaya or further north along the principle Ganges-Brahmaputra partition. These are the Kali Gandaki, the Trishuli River, and the five principle tributaries of the Trishuli known as the Daraudi, Seti, Madi, Marsyandi and Budhi.
In Nepal, Sapta Gandaki alone has a tremendous hydropower capability of 20,650 MW (monetary exploitable potential is 5,270 MW) out of an aggregate assessed capability of 83,290 MW (financially exploitable potential is 42,140 MW). The nation has so far possessed the capacity to produce just around 600 MW of hydropower out of which the Gandak bowl ventures contribute more than 44% - 266 MW. The hydropower tasks manufactured are the Trisuli at Nuwakot (21 MW), Devighat at Nuwakot (14 MW), Pokhra (1MW) and Western Gandak HEP, at Nawalparasi (15) MW, financed by the Government of India, Marsyangdi at Tanahu (69 MW), Kali Gandaki at Syanja (144 MW), and Syange 2 MW. Center Marsyangdi HE Project (70 MW) at Lamjung is under conclusive phase of development. A few noteworthy tasks are on the blacksmith's iron for execution sooner rather than later. With Government of Nepal now agreeing need to private-area support in a multi-pronged methodology, the pace of hydropower advancement will get quickened.
A noteworthy Indian firm has gone into an offer buy and joint endeavor concurrence with a Nepalese firm to gain 80 for every penny stake of Nepalese Company for improvement of the Upper Marsyangdi HEP (250MW). Accomplishing the monetarily exploitable potential need would no more be a delusion.
Supposedly there are a few other significant tasks being sought after by the Government of Nepal for private division investment on IPP basis.
