Minnesota Lakes: Past, Present & Future
Minnesota is blessed with thousands of beautiful lakes, that enhance our lives and serve as a habitat for a diversity of living things. Since they formed at the end of the last glacial period they have been heavily modified by human activity — in general to their detriment. Currently they are challenged by the problem of eutrophication, the introduction of exotic organisms and the uncertainty of climate change. We must take steps to protect our lakes if they are to continue to add to our quality of life and provide a home for fish, waterfowl and other aquatic organisms.
