Middle & Upper Columbia River
Since 2001, we have performed 11 detailed reach assessments and developed restoration strategies on over 100 miles of stream within key watersheds of the Methow, Entiat, Wenatchee, Yakima, and Klickitat rivers. This up-front planning work has led to over 50 actual in-the-ground restoration projects for the Yakama Nation. Projects have included main channel, off-channel, riparian, and floodplain habitat enhancement. Specific project types have included dam removals, culvert replacements, side channel creation, levee removal, large wood structures, headwater meadow restoration, restoration of incised channels, fish screening, and bank habitat complexity. Below are snapshots of a few of our reach assessments and completed projects.
The Toppenish 3-way restoration included levee removal, abandoned diversion structure removal and design of new irrigation routing to existing diversion upstream with a fish screen, channel construction and remeanding, alcove activation, reconnected floodplain, floodplain roughness, setback levee to protect downstream infrastruture, and large wood jam installation.
