The Bad River Watershed Association will replace five road–stream crossings to enhance habitat for native brook trout and other aquatic organisms. This work will reconnect more than 19 miles of upstream habitat, reduce sediment inputs by 68 tons per year, and reduce velocities and in-stream scouring associated with high flows. The Bad River watershed is the largest contributor of sediment to Lake Superior on U.S. shores, with much of the sediment released by poorly designed road–stream crossings. Additionally, the road–stream crossings also act as barriers to upstream movement of fish and other aquatic organisms. Five road–stream crossings will be replaced in critical brook trout habitat, which will reopen cold water stream habitat, benefit macroinvertebrate and amphibian habitat, and reduce sediment loads to the Bad River and Lake Superior. To evaluate the effectiveness of the road–stream crossing replacements, the project will monitor erosion, fish recruitment, and stream habitat quality.
