Description    


Lewis County Public Works used this funding for a restoration project located in Skook Creek, a tributary to the Cowlitz River near the town of Ethel, in Lewis County, Washington. Removal of the barrier opened a drainage area of 2,645 acres. The goal of this project was to provide fish passage by removing two existing 48-inch diameter culverts and concrete apron with an 8-ft. hydraulic drop. A single span 120-foot concrete bridge, designed streambed, rock weirs, and streamside plantings were installed. In-water construction was completed during the fish window of one construction season. Visual fish monitoring by Lewis County continued for three years.

The barrier was located 1.1 miles upstream from the confluence with the Cowlitz River. Removal of the barrier opened 10.8 miles of Skook Creeks main stem and tributaries, including 4.2 miles of spawning and rearing habitat historically used by anadromous fish. Currently, steelhead, coho and cutthroat trout now use the stream reach above the new bridge. Under ESA, steelhead trout and coho salmon are listed as a threatened species while cutthroat trout are being considered as candidates for federal listing. These species are considered depressed by the WDFW.

This project addressed the primary issue identified in the Draft Limiting Factors for WRIA 26, access to spawning and rearing habitat. Other enhancements in the basin included water quality protection of 370 acres in the Skook Creek headwaters through nutrient management programs.

Project Benefit    


The goal of the project was to connect isolated habitat to increase the range and distribution of salmon.



The objective of the project was to increase access to areas blocked by human-caused impediments.
