About The River

The Green River originates in the windswept mountains of Wyoming, finding its source within the Bridger National Forest. It winds over 730 miles, carving a beautiful path through spectacular landscapes. Its majesty can be chiefly admired below the Fontenelle Reservoir.

The river’s history is rich and fascinating. It dates back to the time of the native tribes, having served as an essential source of water, transportation, and sustenance.

  • Early expeditions in the 19th century, led by pioneers like Major John Wesley Powell, navigated this untamed waterway, documenting its unique geology and contributing to our understanding of the American West.
  • Industrialization in the 20th century saw the construction of the Fontenelle Dam in 1961. This major infrastructure project created the Fontenelle Reservoir, a crucial water storage facility for Wyoming.
