Degraded Channel and Riparian Areas Degraded Channel Structure and Complexity
The amount of large wood in the upper Abernethy Creek stream channel is very low due to a history of stream cleaning and timber harvest that reduced conifer levels in the riparian area. The proposed project will increase the amount of large wood contributing to channel structure and complexity in upper Abernethy Creek upstream of Beaver Lake. Logs will be placed via heavy-lift helicopter in strategic locations over 6 miles of stream channel. Logs will create cover over the stream channel and maintain existing pool habitat, sort gravels to improve spawning conditions, and enhance floodplain connectivity.

Targeted Performance Measure

  • Large Wood Placement: 20,750.40 lf
  • Off-Channel Wetland Area Increase: 1,500,206.40 sq ft

Focal Species

  • Coho
  • Pacific Lamprey
  • Steelhead

Project Types
