Project phase: facility operations

The Harris Creek Fish Passage Restoration – Snoqualmie Basin 2015 project is located approximately 3 miles east of the city of Duvall, north of Stillwater, at the intersection of NE Stossel Creek Way and NE 138th Place.  Harris Creek is a tributary to the Snoqualmie River, entering the right bank at approximately river mile 19. The project location is approximately five miles upstream from the confluence with the Snoqualmie River.

Project purpose

This project restored fish passage to more than 4 miles of upstream habitat on Harris Creek and its tributaries.  Harris Creek supports coho, steelhead/rainbow, and cutthroat trout.

The old fishway adjacent to the 101H-02 culvert had a 1.9ft outfall drop from its upstream baffle (behind the stadia) and a 1.2ft outfall drop at the outlet (photo foreground).

Project features

The Harris Creek Fish Passage Improvement Project:

  • removed a 25-foot long failed concrete fishway and
  • installed a roughened channel of well graded streambed mixture and logs for approximately 95-feet.

Issues moving forward

Per WDFW and ACOE permit requirements we will monitor the vegetation establishment for 3 years to confirm 80-percent survival.  Our ERES monitoring group will monitor channel and vegetation responses over the next 5-years under the adopted monitoring plan established during the design phase.

Key lessons learned and/or vexing issues that need follow up

Other than some initial design delays due to workload conflicts, this project actually went quite smoothly.
