Names and etymology
Bhote koshi is the Nepalese name (Nepali: भोटे कोशी, romanized: Bhōṭē kōśī). In Nepali language, the word "bhoṭe" or "bhoṭiyā" means Tibetan;[4] and the word "kosi" means river.[5] As such, the name is not unique, the western tributary of the upper Dudh Koshi is also called Bhote Koshi.[6]
Poiqu (Tibetan: བོད་ཆུ) is the common name for the river on the Chinese side.[7][8] It is also transliterated as Boqu via Chinese (Chinese: 波曲).[9] and as Po Chu by early 1990s Everest expeditions.[10] This name means "River of Tibet."[11] This too is not a unique name, as it is also ascribed to Yarlung Tsangpo. The formal name of the river in Tibetan is Matsang Tsangpo (Tibetan: མ་གཙང་གཙང་པོ།).[8][7]

Tourism and sports
The Bhote Kosi is used for both rafting and kayaking. It is the steepest river rafted in Nepal, with a gradient of 15 m per km. Bungee jumping or swinging over the Bhote Kosi has been described as the ‘ultimate experience’.[14]
The river carves a steep and direct drop at the top that gradually eases to more placid streams and calmer pools with a 46-km run at the Lamosunga dam. The rapids are class IV-V at high flow, and III at lower levels. The river is steep and continuous with one rapid leading into another.
