Dominant riparian vegetation: Shrubs (willow, salmonberry, some small alder) Primary channel length (meters) and area (m²): Secondary channel length (meters) and area (m²) 854 : 9,2 33 : 7,38 VWI average: 2 VWI Range: 2-2 Average Gradient:.7% Pieces LWD per m:.8 Wood Volume (m³) per m:.3 Percent pools: 36% Complex pools (LWD pieces>=3): 4 Pools >=m deep: 4 Percent substrate (avg): Silt / organics Sand Gravel Cobble Boulder Bedrock All units Pool units Fast water units SURVEY COMMENTS: This is a post-treatment habitat and cross-section survey at a channel re-activation site. Boulder and log habitat structures were present within the survey. Planted riparian vegetation was being actively watered. A large off-channel pond had been connected to the creek, creating alcove habitat.
