Fish Passage Bypass: Crooked River Watershed Council - Aquatic Contracting

Prineville, OR

Aquatic Contracting LLC was contracted by the Crooked River Watershed Council to construct a 350 foot long bypass channel providing fish passage (for reintroduced steelhead) around a 7 foot high, 120 foot wide concrete diversion dam by creating a nature-like fishway. The project included construction of a sheet pile grade control structure, 11 weir/step-pool complexes, 350 feet of new creek channel, a 60 foot long pedestrian bridge, over 2,000 feet of geotextile encased soil wraps, and a log deflection boom. Aquatic Contracting constructed the project during December 2008 and January 2009 and then returned to install additional native plants in March 2009.

Aquatic Contracting received a formal letter of appreciation from the Crooked River Watershed Council for our expertise and responsiveness on this project.
