Description    


This project created 2,500 ft of new side-channel habitat on on the North Fork Lewis River near river mile 13.5. The designs utilized to construct this project was provided as part of SRFB Project #08-2059 “North Fork Lewis Side-Channel Design”. This project was located in reach Lewis 5, a Tier 1 reach in the Lower Columbia Salmon Recovery and Fish & Wildlife Subbasin Plan (LCFRB 2010).

The project has created and enhanced important spawning, rearing, and adult holding habitat for ESA-listed salmonids in the North Fork Lewis River. The newly connected side-channel habitat has hundreds of logs placed for LWD complexity and provided excellent rearing habitat for tenths of thousands of juvenile coho, chinook and steelhead. In addition, we have observed chinook, steelhead and coho adults spawning in at the inlet of the side channel. The project has enhanced key habitat for ESA-listed salmonids and created pool-riffle habitat with LWD placements, and connected off-channel (backwater) habitat to benifit rearing juveniles seeking velocity refuge during high flows. The project also included the rehabilitation of approximately 200 feet of a perennial spring-fed tributary using channel re-grading and LWD placements.
