TMLF Improves Rainbow Trout Habitat

  • September 20th, 2013  

     

    Early this September, 2013, the Trans Mountain Legacy Fund (TMLF) partnered with Canadian National Railway (CNR) to improve rainbow trout habitat in Mount Robson Provincial Park. The project area, known as Site 26,  is located just off of Highway 16, along the CNR route northwest of Moose Lake. In order to restore fish passage for juvenile rainbow trout, rock weirs were constructed to slow stream velocities and raise the water level.  The crew embedded the right pipe in the streambed, and added rocks and other materials to more closely simulate rainbow trout habitat (see photos). The TMLF will monitor this site over a five-year period to evaluate fish movement post-construction.

     

    Thanks to CNR, and Mark LaRuez of Triton Environmental Consulting for making this project possible.
