DESCRIPTION
This project implemented Phase 1 of an instream and riparian restoration project on the upstream portion of the braided reach of the Skykomish River between Gold Bar and a large right bank riprap embankment downstream along the Burlington Northern Santa Fe railroad tracks. The project built upon the Braided Reach Restoration Assessment, which identified strategic points in the reach that would serve to reduce intervention impacts while maximizing results. This helped implement cost conservative projects at locations where the best results were achieved with a minimal expenditure of funding and energy, maximizing the potential of the system itself to create and preserve essential habitat and habitat functions.
The accomplishments of this phase consisted of:
1. Augmenting an existing log jam to provide refuge, create holding pools, and to add complexity and edge habitat.
2. Instream flood fencing at 32 selected locations that increased channel roughness and complexity. (Flood fencing is a bioengineering technique. This technique creates small scale roughness features spanning a large area, whereas large wood jams create large roughness elements over a small area)
The intent of this project was to enhance juvenile salmonid rearing habitat. Wood structures were designed and located to encourage the development and reconnection of off-channel habitat, to increase edge habitat, and promote further log jam development. Specific fish species expected to benefit from this project included Chinook, chum, coho salmon and steelhead.
