Webinar: Variable Warming in Lakes of the Upper Midwest and Implications for Sport Fish

Science Center Objects

Check out this webinar to learn more about how warming temperatures are affecting lakes in the Midwest and the fish they support.

Climate change is predicted to alter sport fish communities in Midwestern lakes, but managers currently have limited information on individual lakes that can be used to set local expectations or intervene with mitigation strategies. Northeast and North Central CASC supported researchers, with strong participation from the Midwest Glacial Lakes Partnership, have combined existing fish and water temperature observations to build models that estimate daily water temperatures and fish habitat metrics for thousands of lakes in North Dakota, South Dakota, Minnesota, Wisconsin, Iowa, Michigan, and Indiana. This presentation discussed key findings from several studies, including fishery responses to warming and variability in sensitivity to warming across lakes. It also covered the use of data visualization to reach managers and the general public with the results.
