Local Level Indicator on Adherence of Stream Crossings to Standards is now available to view and download
February 12, 2010
Throughout the forest regions of North America, the two impacts from land management activities that pose the greatest risk to the conservation of aquatic resources are obstruction of fish passage and sedimentation at stream crossings. There are approximately 2,070 locations where permanent roads cross streams within the Foothills Research Insitutes core study area. There are also several hundred railway crossings. Older crossings were built to the standard of the day, but for small streams, maintaining fish passage may not have been a requirement at the time. In addition, runoff from gravel roads can cause sedimentation which adversely affects aquatic invertebrates and fish. These factors warrant a system-based approach that looks for innovative and cost effective solutions to manage environmental risks associated with stream crossings at the landscape scale.
This is the last indicator that was completed for the Local Levels Indicator Program which wrapped up last year. Stay tuned over the next few weeks for the release of a .pdf file that combines all of the indicators into one document. To view the Indicators click here.
