TRAVERSE CITY, Mich. -- A three-year study has found that Lakes Erie and Ontario are the most seriously threatened of the Great Lakes, along with large sections of the Lake Michigan shoreline.
Scientists on Monday released findings from their analysis, including a detailed set of maps that lists 34 environmental problems such as invasive mussels, toxic pollution and runoff and shows where they are concentrated.
Lead researcher David Allan of the University of Michigan says the project will help state and federal officials set priorities as they continue a multi-year restoration program for the lakes.
Among the maps is a multicolored image of the entire region that pinpoints the best- and worst-off areas, based on scientific reports, satellite maps and a survey of experts. It depicts the majority of Lake Ontario as highly stressed.
