Presented by Dr John Downing Director of Sea Grant College program. "Clear Information on Murky Lakes: How to Keep Them Minnesota Nice." Minnesota lakes are well known for being clear and healthy. As we enjoy them, there is a danger of loving them to death, and everyone can help keep our water quality "Minnesota Nice". Unfortunately, lakes in North-central Minnesota are decreasing in water clarity faster than those in other regions of the state. This talk gives the reasons for these changes and practical advice on how to keep from damaging our region's valuable lakes and streams.
