Description
The specific objective of this Project is to construct 28 LW features along 0.7 miles of Somerville Creek. The structures will contain 131 pieces of LW, including 19 pieces with rootwads attached. The completion of this project will raise the LW count in the project reach to 213 pieces per mile, which far exceeds the very good threshold as defined in the SONCC Coho Recovery Plan (NMFS, 2014). Additionally, 80 trees will be planted in the riparian zone along the project reach.
Project Benefit
The Project will improve instream habitat by enhancing spawning and rearing habitat by increasing pool area and depth, increasing shelter complexity, capturing and sorting spawning gravels, increasing floodplain and side channel inundation, recruiting large and small wood, and providing velocity refugia during high winter flows.
