factors affecting water clarity MN

How much older do you think these Southern lakes are than the Northern ones?... 5 minutes older? The glacial melt that happened many, many years ago happened on a large scale and basically at the same time. When you look at the pre-historic time line of the geology of Minnesota, this was all just a blink of the eye. I would be interested to know the bar-tenders name who was your "reliable source".

apparently,,, from some google searching and such.. approximately 2000 years difference between the north and the south half of minnesota.. maybe just enough difference to affect the humus debris that found it's way into the lakes.
