DESCRIPTION
South Puget Sound Salmon Enhancement Group used this funding for a fish passage restoration porjecct at approximately river mile 2.6 on Woodland Creek, which drains into Henderson Inlet. Two squashed five-foot aluminum culverts were partial barriers that failed to satisfy the WDFW fish passage criteria. Due to earthquake damage, their structural integrity was compromised and they would have eventually become total blockages.
This project replaced these failing culverts with a forty-foot span Big R prefabricated steel bridge with steel piling abutments. About seventy feet of stream channel was re-created using natural streambed materials. The bridge was elevated about one foot higher than the existing road and the road was re-graded to a matching slope. The contractor installed guardrails and repaved the bridge deck surface with a built-in crown to run storm water away from Woodland Creek. The span handled the first winter flows very well, The landowners and the community noticed a drastic improvement and salmon were seen utilizing the upstream habitat a few weeks after the project was completed in late October, 2002.
Species benefiting from this fish passage project include: chum, coho, cutthroat trout, steelhead, and hatchery-origin Chinook salmon of the Woodland Creek drainage. The bridge allows unimpeded fish passage for salmonids at all life stages.
