Degraded Channel Structure and Complexity
Johnson Creek Confluence Habitat Enhancement Project

Planning/Design
The confluence of Johnson Creek with the Willamette River serves as important salmon habitat not only for Johnson Creek fish but also those runs destined for the upper Willamette as well. Because of its cooler water temperatures, the lower 1.5 miles of Johnson Creek is used by migrating spring Chinook as cold water refugia. In 2011 JCWC added 150 pieces of large wood to the confluence. Since that time half the wood has worked its way free and floated downstream. We now know more about stress forces and eddies in the area. This phase 2 project will supplement the phase I work and use more advanced installation techniques to ensure the structures perform and stay in place.

Focal Species

Focal Species

Large wood structures will provide cold water rearing and resting habitat to adult and juvenile chum salmon. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.
Large wood structures will provide cold water rearing and resting habitat to adult and juvenile coho salmon. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.
Large wood structures will provide cold water rearing and resting habitat to adult and juvenile fall Chinook salmon. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.
Large wood structures will provide cold water rearing and resting habitat to adult and juvenile Pacific lamprey. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.
Large wood structures will provide cold water rearing and resting habitat to adult and juvenile spring Chinook salmon. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.
Large wood structures will provide cold water rearing and resting habitat to adult and juvenile steelhead. The large wood will be installed at a density over 25 cubic yards per 1000 linear feet of stream, meeting Oregon Department of Fish and Wildlife's Recovery Plan criteria for wood placement density.

Project Types

Project Types

All affected landowners and adjacent landowners have been contacted about the project. We've discussed the project at length many times with each and although there is no formal agreements signed yet, the landowners have expressed support of the project and we plan to obtain formal agreements once the design is further developed.
This project is an instream habitat restoration project that will result in increased habitat complexity in the lowest reach of Johnson Creek and its confluence with the Willamette River by installing log structures, removing invasive vegetation, and planting native trees and shrubs.
