In 2010, the Spread Creek dam, an obsolete, crumbling diversion dam for irrigation located just outside of Grand Teton National Park on Bridger-Teton National Forest lands was removed by a partnership effort led by TU's Wyoming Water Project, opening up over 50 miles of Spread Creek to migratory Snake River cutthroat trout for the first time in over 50 years. Since the dam was removed and replaced with a fish passage-friendly diversion structure and new water delivery system, project partners have documented successful fish movement through the project area – but have also discovered that native fish, including migratory Snake River fine-spotted cutthroat trout and bluehead suckers (a Wyoming Species of Greatest Conservation Need) are being entrained in the Spread Creek irrigation system. This project will install a fish screen on the Spread Creek irrigation system to protect native fish.  One Fly has funded earlier phases of this project.
