Fish Passage Restored at Mile 9 Culvert in Jasper National Park

  • April 5th, 2014  

    Another successful aquatic restoration!

    Prior to the work of the TMLF, the Mile 9 culvert was prone to hanging when not backwatered by the Athabasca River at higher flow levels. It acted as a fish barrier, preventing lake whitefish from migrating upstream in the fall to the lake across the highway.  Now whitefish are free to move year-round. This connectivity will benefit other species as well, including bull trout. Fish are already holding in the outlet pool!

    Special thanks to Mark LeRuez of Triton, along with North West Hydraulics and Farlinger construction who completed construction on Monday, April 2, 2014.
