The Trishuli ( Nepali त्रिशूली IAST triśūlī ; Chinese  特 耳 蘇里 河 , Pinyin Tè'ěrsūlǐ Hé ) is the left source river of the Gandak ( Narayani ) in central and southern Nepal .

The upper reaches of the Trishuli in Tibet ( People's Republic of China ), the Kyirong Tsangpo , rises in the Tibetan highlands north of Dzongkar and flows through the Kyirong district in a southerly direction. The Trishuli cuts through the main Himalayan ridge. The breakthrough valley runs between the mountain ranges of Langtang Himal in the east and Ganesh Himal in the west. The Trishuli flows along the western border of Langtang National Park . At Bidur it gradually turns to the west. It takes in the larger tributaries Budhigandaki , Marsyangdi and Seti Gandaki from the right. To the north of Bharatpur , it finally joins the river Kali Gandaki, which flows in from the west, to form the Narayani (called Gandak in India ), an important left tributary of the Ganges . The river length from the Chinese border to the mouth is about 200 km.

The Trishuli is one of the most popular rafting waters in Nepal.

In the opinion of the local residents, the water quality of the Trishuli was so good until the beginning of the millennium that you could drink water directly from the river. However, due to the economic development of Nepal, the water quality has deteriorated considerably.

Hydropower plants

  • Run-of-river power plant above Trisuli (24 MW, 7 units, built 1967–1970) ( ⊙ )
  • Nepal Upper Trishuli-1 with 216 MW near Dhunche (planned)
  • Galchh with 75 MW near Dhodbesi (planned)
