Stout Creek Assessment & Restoration Plan

Watershed and Stream Assessments
Client / Agency
North Santiam Watershed Council
Mehama, Oregon
2008 to 2009
Project Description
The North Santiam Watershed Council (NSWC) retained River Design Group, Inc. to complete an existing conditions assessment and restoration prioritization plan for Stout Creek. This effort followed the North Santiam River Watershed Assessment (E&S Environmental Chemistry 2002) which provided an evaluation of the drainage at the watershed scale. The Stout Creek Assessment served two purposes. First, as a reach assessment, it presented information on historical and existing conditions based on field data collection, remote sensing, and existing data review. Secondly, the document served as a stream corridor restoration plan that prioritized aquatic habitat improvement and conservation projects in the 2.5-mile assessment reach in Lower Stout Creek. Restoration and conservation actions were specified for each of three sub-reaches. Restoration Actions were prioritized based on expected ecological benefits, costs, and risks. Conservation Actions were also presented as a means to preserve remaining floodplains, riparian vegetation, and upland forests.

RDG implemented the Riggs project in 2009 followed by two other projects on Lower Stout Creek including large wood placement projects on the Heritage Nursery and Boedigheimer reach in 2010. RDG will oversee construction in 2011on two additional large wood projects on a section of Stout Creek between the Riggs and Boedigheimer projects.
