Description    


This grant funded instream restoration work on approximately 1/4 mile of lower Trout Creek, a tributary to the Wind River. The instream restoration work is part of a larger project that removed Hemlock Dam, along with an estimated 50,000 cubic yards of sediment that had accumulated behind the dam. The grant funded construction of a new channel in the reach previously occupied by the reservoir.
Trout Creek provides habitat for Lower Columbia River steelhead and once produced a disproportionately large share of the steelhead in the Wind River system. Upstream of the project reach are 15 miles of potentially excellent steelhead habitat, all of which is on national forest lands. Efforts have been underway for the past decade or more to restore healthy habitats in the upper watershed. Migrating fish in lower Trout Creek were exposed to a host of hazards resulting from the dam and reservoir, including lethally high water temperatures, habitats devoid of suitable substrate and cover, and direct mortality on dam structures.
This project restored natural riverine and riparian processes in lower Trout Creek. The goal of the project was to reduce peak water temperatures, restore suitable substrates and habitat diversity both in the project reach and in the 2 miles of Trout Creek downstream of the project reach, and provide unobstructed passage to upper Trout Creek.

Project Benefit    


The goal of the project is to improve instream morphology and habitat in salmon bearing streams. The objective of the project is to increase instream cover, spawning, and resting areas.

      Project identified in a Plan or Watershed Assessment
      Hemlock Dam was identified as a significant factor affecting steelhead recovery in the Wind River in virtually every analysis completed for the Wind River watershed. The Forest Service Wind River Watershed Analysis conducted in 1996 and updated in 2001 identified Hemlock Dam removal as the highest aquatic restoration priority in the subbasin (USFS 1996, 2001). The dam was also ranked as the number one factor limiting steelhead recovery in the Limiting Factors Analysis conducted for the Wind Rive
