Located approximately 1 mile south of the the town of Lostine on the Lostine River, was an irrigation diversion which failed to meet state and federal fish passage criteria. In cooperation with Oregon Department of Fish and Wildlife, the GRMW developed a project that would restore aquatic organism passage to all species and life stages, maintain the necessary physical characteristics to accommodate irrigation practices, and result in a river channel which is both natural in appearance and function.
The Sheep Ridge ditch diversion on the Lostine River in Wallowa County, Oregon is a passage barrier to ESA Listed fish including Chinook salmon (Oncorhynchus tshawytscha), steelhead trout (Oncorhynchus mykiss), bull trout (Salvelinus confluentus) as well as several other aquatic species. Engineering and design for the project is substantiated by the success of similar projects including one recently constructed directly downstream at the City of Lostine diversion. Partners include the Sheep Ridge ditch company, ODFW, GRMW and adjacent landowners Bill Norman and the Cherry family. Videos courtesy of Mitch Daniel at NPT. Read more about this project here.
