Restoration of Aquatic Native Fish Habitat
The purpose of this project is to restore geomorphic, hydrologic
and biological process to approximately 5.7 miles of Thritymile Creek to improve habitat for the threatened Mid-Colombia River steelhead. Habitat impairments currently include:
• High surface water temperature
• Lack of channel complexity
• Ephemerally low and/or intermittent surface flow
