The two original culverts, which were 42 inches in diameter and 30 feet long, constituted a fish passage barrier to adults and juveniles at most flows, preventing them from utilizing 1.5 miles of HIP habitat that lay above the culverts. The Coquille Watershed Association was contracted to replace the culverts with a single oversized 9x34 round corrugated metal pipe. After installation of the culvert, 40 cubic yards of pea gravel was placed throughout the bottom to create a more natural surface. The replacement culvert re-opened 1.5 miles of HIP Coho habitat to juvenile and adult salmonids.

Project Benefit    

The completion of this project will maximize the fish passage benefits for Coho and Steelhead over 1.54 miles of stream.

      Monitoring text (from Phase I)
      The Subbasin Plan contains a Research, Monitoring and Evaluation Plan and an Adaptive Management Plan which work together to focus restoration work where it does the most benefit. Required annual and multi-year reports of the Subbasin Plan compile data from a variety of sources to monitor progress toward achieving the strategies of the plan. Implementation monitoring will document: 1) if projects were constructed as designed and on schedule; 2) the percent of total landowners contacted; and 3) number of miles where restoration of winter rearing restoration was accomplished. Effectiveness monitoring is required for all beaver re-introductions. All monitoring results are shared with stakeholders and are available to the public at www.coquilletribe.org
