Soda Creek Habitat Enhancement Project (Phase II)

This project will improve habitat for rearing salmonids by adding large wood to the 0.37 miles of stream channel to stabilize eight active knickpoints, capture sediment, reduce drop heights, improve habitat complexity, and create cover in pools. This process-based approach will include building 28 structures using at least 69 pieces of LW to specific bed control elevations to step-up the channel downstream of each knickpoint. This project is the 2nd phase of restoration in Soda Creek; Phase I will be implemented in 2026 and includes replacing an aging culvert that is a partial fish passage barrier and constructing four alcoves with pools and large wood structures in the reach just downstream from the Phase II reach.

This project will improve habitat conditions by stabilizing erosion knickpoints and enhancing pool shelter and large wood density. Large wood will be placed downstream of knickpoints to capture sediment, reducing drop heights into smaller, navigable steps. The result will be increased large wood density, improved juvenile fish passage, and enhanced rearing habitat for salmonids.
