Green Lake, home to lake trout and other species, was deemed “impaired” by the DNR in 2014 because of its low levels of dissolved oxygen. Faculty members Chris Kucharik, Anita Thompson and Jake Vander Zanden are leading an effort to synthesize data to help researchers understand connections between land use, climate, and water quality. Green Lake is located in an agricultural watershed, which has contributed to increased phosphorus in soils. Runoff and erosion from this nutrient rich landscape supports increased algae growth in the lake and reduced water quality. Declines in oxygen levels can cause cold water species to die out. The information gathered from this study can help other communities going through similar situations.
