Stream Crossings and Fish Passage Barriers
Roads and Streams are the two linear features of the landscapeāRoads link human settlements while streams following the path of least resistance downhill. Wherever Transportation Networks cross steams there is a risk that the road damages stream functions, or that the stream damages the road. Roads are fixed and stable. Streams are dynamic and evolving. Salmon use streams annually for spawners to reach spawning grounds, and for young to disperse and find forage and refuge. Roads cross streams using culverts and bridges, and the use of culverts creates a set of problems.
