About The River

Meet the Clark Fork River-Above Missoula, a vibrant and historic waterway in Western Montana. This captivating river has a rich tapestry of history dating back to the ice age, when the Missoula floods, one of the largest known floods in earth’s history, carved out the river’s current course.

Over the years, the river has seen many changes. In the mid-19th century, it became a crucial transportation route during the gold rush era. Later in the 20th century, the river was instrumental for hydroelectric power generation and for logging operations. Noteworthy among these are the following:

  • The Milltown Dam, built in 1908, that harnessed the Clark Fork River’s power to generate electricity, contributing to the river’s industrial heritage.
  • Also, the removal of Milltown Dam in 2008 uncovered a massive deposit of heavy metals, leading to one of the largest Superfund cleanup projects in US history.

Today, Clark Fork-Above Missoula continues to be a treasured resource providing recreational activities like fishing, rafting, and wildlife viewing. Truly, it’s a river that’s seen and survived it all, holding firm in its water the echoes of a tumultuous and transformative history.
