Project Description
The Anderson Ranch located on the Sprague River near Beatty, Oregon, was one of the four mainstem Sprague River restoration priorities highlighted in the Sprague River Master Plan. The 1873 General Land Office maps suggested the Sprague River had shortened over time due to a channel avulsion that excised two meanders measuring 3,700 ft in length. The project goals included re-establishing the historical channel alignment and enhancing instream, wetland, and riparian habitats to benefit the native fish and wildlife communities. River Design Group prepared an assessment and design for the Anderson Ranch in 2008. The project included reactivating the historical meanders, converting an avulsion channel to backwater habitat, installing over 25 large wood habitat structures, creating and enhancing wetlands, and implementing a revegetation strategy. RDG completed an existing conditions survey, completed discharge measurements and used a LiDAR/bathymetry dataset to build assessment existing and proposed river morphologies. The engineering design included a 1D HEC-RAS model to evaluate existing and design channel hydraulics. RDG completed the project implementation in 2009. RDG collaborated with the U.S. Bureau of Reclamation, USFWS, Natural Resources Conservation Service, the landowner and a local heavy equipment operator to complete the project. Pre-project and as-built surveys were completed for monitoring river response to the project.
