Berwick Creek at Borovec Fish Passage Design

This planning project proposed to produce a final design for a current fish passage barrier only 67% passable due to velocity on Berwick Creek in Lewis County, WA. The current structure is two 6-foot wide x 4.5-foot tall corrugated metal squash culverts and we plan to replace it with concrete box culvert. There are currently other barriers both upstream and downstream which are being addressed by other sponsors through both designs and construction. Once all other barriers (two downstream and two upstream) are addressed, this culvert will provide unimpeded access to 9.57 miles of habitat for coho salmon and 7.88 miles of habitat for winter steelhead. Additionally, the design of this project was proposed to ensure that sedimentation effects on water quality are also considered. The some funding was spent on outreach, monitoring planning, project staking and cultural resource boundary research/management. $16,000 of the SRFB award was used towards project staking and cultural resource permitting. Due to the unexpected change in willingess and participation from the landowner, this project will not move forward and has been concluded as incomplete.

The testing and evaluation was not fully completed so the design was not finalized. but project closed. Construction of this project would have provide unimpeded access to upstream spawning and rearing habitat.
