Description    


The Palouse Conservation District (PCD) replaced a perched road culvert along Steptoe Creek in southeastern Whitman County, WA. The culvert passed under Steptoe Canyon Road, approximately 0.7 miles upstream of the confluence with the Snake River. A new bridge replaced the culvert, which had been a complete barrier to fish passage. The bridge was designed with SRFB funds (agreement #14-1914P). In conjunction with bridge installation, construction included a stream channel realignment with a riffle-pool channel bed design. Whitman County Public Works (WPW) collaborated with PCD on this project, offering in-kind matching funds in the form of crew labor and equipment use during construction. A cultural resource monitor was on-site during all phases of excavation due to the sensitivity of the site identified during the project design phase. Removing the perched culvert opened up approximately 1.5 miles of Steptoe Creek to summer steelhead use. An additional 2.0 miles of habitat will become available once an upstream barrier culvert is replaced. PCD is currently assisting the landowner to enroll the creek into the Conservation Reserve Enhancement Program (CREP), allowing the landowner to receive cost-share and incentive payments to do enhancements along the stream channel, including livestock improvements and riparian plantings.

Project Benefit    


To provide fish passage to 1.5 miles of habitat within Steptoe Creek to benefit summer steelhead. An additional 2.0 miles of habitat will become available once an upstream barrier culvert is replaced.
