Freeways for Fish

Our Achievements

Over the past decade, the Geos Institute helped restore over 1,200 miles of the beautiful Rogue River and its tributaries.

These stream reaches were historically available to native fish, but development in the 20th century – like the creation of dams and diversion channels – reduced the amount of available spawning and rearing habitat. In combination with many other threats, the health and productivity of native salmon and trout diminished in the 1900s.

From 2005 to 2015, Freeways for Fish helped to reopen streams for salmon and trout. From removing several of the worst fish impediments in the state of Oregon to improving the design of water diversion structures, we’re proud to say that native fish now have more room to roam than they’ve had in a century.
