Degraded Channel and Riparian Areas Degraded Riparian Areas and Large Wood Recruitment
This project includes placement of key pieces of large wood in the back channel alcove and floodplain, management of invasive plants, and restoration of native wetland and riparian plant communities. We will also look at retrofitting an existing stormwater outlet to treat stormwater entering the project site. This project will enhance winter rearing habitat for anadromous fish. There are very few opportunities for back channel enhancements on the Lower Willamette River and this project offers a unique opportunity to improve much needed winter refuge habitat for outmigrating juvenile anadromous fish. The majority of this property is owned by the City of Milwaukie and managed by NCPRD.
