Description    


Project implementation was initiated in June 2014. All elements of the project design were implemented as indicated in the “metrics” portion of this document. This project has been successful in achieving the desired outcomes related to habitat availability for focal salmonid species. Rearing and foraging habitats for juvenile spring Chinook salmon and summer steelhead was dramatically increased. For example, prior to the project about 160 meters of side channel habitats existed within the project area. Upon completion, about 0.49 miles of stream was created through channel reconfiguration and connectivity. Another example of project success is the total number of main channel pools created project implementation. Prior to the project about 10 pools existed within the project area. Following implementation approximately 19 new pools are present. 127 structures such as unanchored logs and rocks were placed in the stream. Native riparian plantings were placed in 8.8 acres and covered around 1 mile riparian streambank.. Overall, it is expected that this portion of Mill Creek will increase the survival and growth of focal salmonids inhabiting the project area. The attached report includes two examples of before and after photos with project implementation.

Project Benefit    


Habitat restoration actions will benefit all life stages of focal salmonid species. The addition of deep pools, with cover, provides habitat for migrating adult salmonids and rearing juveniles. Juvenile salmonids now have a full suite of low-velocity, high-cover stream-margin habitats. These low-velocity areas are crucial for newly hatched salmonids until they become large enough to forage in pool and riffle habitats. Thermal (hyporheic exchange) and velocity refugia (high flow events) are now available through increased floodplain connection and the construction of off and side channel habitats. Over time, planted riparian vegetation will decrease solar exposure to stream channels, resulting in the maintenance of cool stream temperatures. Allochthonous inputs from riparian vegetation plantings will benefit the macroinvertebrate community by providing additional food sources. In general, the survival and growth of focal salmonids inhabiting the project reach of Mill Creek has the potential to increase. Furthermore, fluvial processes that create and maintain complex habitats used by all native fish have been restored at this site.
