Lower Canyon Creek Restoration
Canyon Creek Watershed enters the North Fork Nooksack Floodplain by crossing an alluvial fan, past the Glacier Springs Sub-division. Historically this portion of the system has attracted high spawning concentrations of North Fork Chinook salmon. Habitat conditions declined with debris floods in 1989 and 1990, and in response construction of a levee and constrictions in 1990 and 1994, resulting in creation of a fish passage barrier. Whatcom County Public Works is leading several phases of work to set back the levee, and introduce engineered log jams in an attept to recover fish passage, and improve spawning habitat for the North Fork population, now listed as threatened under The Endangered Species Act.
- Project Aerial in Habitat Work Schedule
- Four active contracts in PRISM related to Lower Canyon Creek
- Canyon Creek deposites sedimentparticles of clay, silt, sand, gravel, or cobble, transported by water, are called sediment. immediately upstream of the Wildcat Reach Restoration.
- Herrera 2007 presents an initial restoration analysis.
- KWL 2003 provides a flood risk assessment.
- Whatcom Land Trust is involved in acquisition and management of some of the properties acquired for the overall project.
- Due to the movement of channel position, engineered log jams may engage the channel at all times but may help establish forested islands that improve habitat services (Herrera 2007).
- It might be a powerful policy case study to document the full state and federal cost of the county decision to permit sub-division on the Lower Canyon Creek alluvial fan.
