Chamberlain Creek Coho Passage Design Project

This project will address CDFW recovery priorities on Chamberlain Creek in the Big River watershed by designing a remedy for a fish passage barrier posed by a corrugated metal pipe that partially prevents adult, juvenile coho, and lamprey passage to 1.6 miles of suitable upstream habitat. The project will design a new stream crossing that will meet fish passage, hydraulic capacity, and debris load requirements. Project partners will evaluate the instream habitat throughout the project as part of scoping and feasibility studies.

The primary expected benefit of this design proposal is year-round passage for adult and juvenile coho to 1.6 miles of suitable upstream habitat. As additional benefits, the design will ensure hydraulic capacity and meet debris load requirements.
