|Stream crossing was identified through MO&RF staff as having potential fish passage issues. The crossing was assessed by DWB Forestry Services Ltd. to fulfill the following: |
• Evaluate to what degree the crossing blocked fish passage,
• Identify the amount of available fish habitat above the crossing,
• Rank the crossing for rehabilitation to facilitate fish
The West Francois FSR is a typical single lane forest resource access road constructed during the late1970s. The crossing at 12.5 km consisted of 2 closed bottom culverts (900mm and 500mm dia.) installed during initial construction. This crossing was subject to a washout in 2007.
The original culverts were considered a partial barrier to fish migration based on channel construction, seasonal high water velocities and chronic beaver issues at the site. (See Photo 1) The original culvert installation scored 42 on a Parker Assessment. Based on these results the culverts were given a high priority for replacement.
