In recent decades, warming temperatures have begun to threaten our freshwater fish and the thousands of outdoor recreation jobs that depend on them according to a new report by the National Wildlife Federation (the Club is a member of the affiliated Wisconsin Wildlife Federation). Warming waters mean lost habitat for cold-water species, the likely encroachment of species typically found in warmer areas, and exacerbation of existing stressors such as habitat loss, pollution, invasive species, and disease. More extreme weather events—especially longer and more intense droughts, heat waves, wildfires, and floods mean increased likelihood of fish mortality. Shorter winters with less snow and ice cover mean shifts in stream flow and water availability through the spring and summer months, as well as lost opportunities for ice fishing.
