How did the Great Lakes condition get so bad?
Climate Change Increasing air and water temperatures mean increased evaporation from the lakes, declining lake levels, and worsened water quality.
Which is the cleanest Great Lake?
Lake Superior is the Cleanest and Clearest Great Lake Because of its somewhat isolated location and long cold winters, not much farming is done along Superior's shores. This means lower amounts of nutrients, sediments, and organic material are floating around the lake.
