Origin of the Name

The name “Saptakoshi” refers to the confluence of seven rivers — Sun Koshi, Indrawati, Tama Koshi, Dudh Koshi, Arun, Tamor, and Likhu — that eventually merge to form the Saptakoshi (Koshi) River, the largest river system in Nepal.

This river is often called “Nepal’s Sorrow” due to its historic floods but also serves as a lifeline for irrigation, hydropower, and transportation.
