Albion River Coho Habitat Enhancement Project - Large Wood Installation

A total of 20 instream features were installed in 0.69mi of Albion River, consisting of 64 LW pieces. During construction, project designs were modified with CDFW approval. 1 feature was added in the project reach with CDFW approval due to a lack of material quality at several other features. The proposed number of logs for these features were installed at the added feature and in other locations in the project reach. Various CDFW approved anchoring techniques were used to hold multiple logs together to form complex structures including wedging logs into existing live mature trees growing on riparian banks and anchoring to live trees with hardware. Available native slash & small woody debris were installed into structures to provide immediate cover for salmonids and encourage floating debris accumulation & aggradation where needed. All FY16 PCSRF funds were spent within the award period (even though the project ended outside the FY16 award period).

The addition of these structures will enhance spawning and rearing habitats by providing cover, increasing pool depth, frequency and complexity, sorting and collecting spawning gravels, and by providing velocity refuge during peak winter flows for juvenile salmonids and migrating adult salmonids.
