DESCRIPTION
The Lummi Nation's Nesset’s Reach LWD Project stabilized eight existing wood accumulations by using pilings within a 1.18-mile reach on the South Fork Nooksack River near River Mile 11. The project addressed reach-scale recommendations for the restoration of habitats that support the recovery of ESA-listed South Fork early Chinook, bull trout, steelhead, and other salmonid populations.
The goals of the project were to: 1) increase key habitat quantity; and 2) increase habitat diversity. To address these objectives, the project sought to increase the residence time and function of wood already deposited in the reach. The reach is an active depositional area for wood, although the lack of large pieces has reduced the stability of logjams so that accumulations rarely persist and function for more than a year. Because wood is a key component of habitat formation in this reach of the South Fork, it is expected that stabilizing the transient wood will create local scour pools and provide diverse habitat in a relatively cool reach of the South Fork. The project utilized cost-effective techniques such as pinning wood accumulations in place with pilings or adding large wood as ballast. The stabilized wood accumulations were expected to trap and hold additional wood moving through the system. Project partners included the Whatcom Land Trust, Whatcom County Parks, Lawson-Curtis family.
