Rivers of Nepal
95 rivers of Nepal, arranged by drainage basin from east to west — Kankai, Koshi, Bagmati, Gandaki, West Rapti, Babai, Karnali and Mahakali — plus a handful of small, independent rivers in the Terai. Each entry notes its immediate tributary relationship, so you can trace a stream back to its main river.
On this list: basin groupings and tributary structure follow Wikipedia's "List of rivers of Nepal". Exact lengths and discharge figures aren't included — the source list doesn't carry reliable figures for most of these, and this project doesn't estimate numbers it can't verify.
