Degraded Channel and Riparian Areas
Degraded Channel Structure and Complexity
The project will enhance in-stream habitat in Abernethy Creek downstream of Hidden Lake. Supplementing existing wood in the channel will increase complexity and increase floodplain/alcove connectivity providing a cool water refuge in a spring-fed off channel cove. The reach is known to provide spawning habitat for steelhead, coho, and Pacific lamprey based on ODFW spawning survey data. Large wood is intended to provide overhead cover and in-channel complexity for spawning adults and rearing juvenile fish. Riparian restoration will remove invasive species and restore native plants. Access for restoration will take place along an existing road entering the Hidden Lake Estates.
