This is a multi-park measure, which includes an inventory and assessment of 1,754 culvert and 51 bridge locations along the major highways and roads in Banff, Kootenay, Yoho, Waterton Lakes, Mount Revelstoke, and Glacier national parks. In Mount Revelstoke National Park the capacity for fish in streams above the Trans Canada Highway is limited, yet we have 89 road-stream crossings that have the potential to maintain aquatic connectivity or divert streams if blocked. Aspects of a stream crossing that may pose a barrier to aquatic connectivity include elevated intake, physical blockage, and structural failure.
