Description    


This was a design-build project that focused on addressing key limiting factors for ESA-listed fall Chinook, coho, and winter steelhead in Bear Creek, Harrington Creek, and the confluence of these creeks with the SF Toutle River. The project extended the range of usable habitat for Chinook in the SF Toutle as well as diversify existing steelhead and coho habitat. Bear Creek is one of the largest tributaries of the SF Toutle and Harrington Creek flows through a wall-based channel for 3000 feet through the SF Toutle River valley, providing critical off-channel habitat. Expanded the floodplain and converted it from a single-thread straight reach into a dynamic multi-thread anastomising reach along 700. Sponsor excavated approximately 3000 cubic yards and place wood. Bear Creek and Harrington Creek confluences with the SF Toutle are located at river miles (RM) 19 and 20 respectively which are at the bottom end of a long valley in the upper watershed. Prior to the eruption of Mount Saint Helens in 1980, this high valley supported significant runs of Chinook, coho, steelhead, and sea run cutthroat trout and LCFEG has used this project as a starting point to recovering these unique and important fish populations. The total instream treatment along Bear and Harrington Creek was 1.04 miles, with 1100 feet of off-channel created, and 92 large wood structures placed for creating habitat. Riparian forest treatments included alder thinning and understory planting on 1.33 miles of streambank and 23.25 acres of riparian habitat with late succession and beaver-friendly species, and enhancing 1400’ of floodplain forest with floodplain roughness logs.

Project Benefit    


i. Protect existing habitat from avulsion by the SF Toutle River
ii. Increase adult holding habitat at the mouths of key tributaries
iii. Increase Chinook spawning habitat in lower ends of key tributaries
iv. Increase habitat diversity, pool frequency, and sediment sorting in tributary habitats to increase the carrying capacity of steelhead and coho
v. Improve riparian habitat from a monoculture of red alder to a diverse, mixed canopy floodplain forest
vi. Increase the amount of food and building material available to beaver
