The report ?Fish Passage Culvert Inspections at Selected Crossings on Dale, Wilkinson, Idabel, Stirling, Affleck and Campbell Creeks?, Columbia Environmental January 15, 2007, identified this location as a partial upstream barrier to rainbow and brook trout migration in 2007 with a score of 38 (project 4673001). The existing culvert (photo 1) had been installed prior to 1995, was not embedded, had combined width that was too small relative to the channel width, high in-pipe water velocities, was seasonally dry due to being installed too high in the stream profile and could convey only 57% of anticipated Q100 flows.
A hydrologic assessment and new crossing design were completed in March 2007 (project 4673004). Materials were purchased in early 2009 (project 5049002) and the installation of the structure occurred September 13-16, 2009.
The assessments that contributed to the decision to restore fish passage at this crossing are: 1. ?Fish Passage Culvert Inspections at Selected Crossings on Dale, Wilkinson, Idabel, Stirling, Affleck and Campbell Creeks?, Columbia Environmental January 15, 2007, Score = 38;
