About the Portneuf River – Pocatello

Shoshone and Bannock tribes initially populated the region, and the river served as a staple for survival. European trappers arrived in the mid-18th century, and the river’s name – Portneuf – was derived from a French trapper.

Key facets of the river’s history include:

  • The transportation of beaver pelts along the river during the mid-1800s fur trade.
  • The river’s crucial role in irrigating farms in the early 20th century.
  • The Fun Run river float, an annual Pocatello tradition, where locals float down the river on inner tubes, has been taking place since the 1970s.
