Water levels on all the Great Lakes are lower. I fished yesterday in the Sturgeon Bay area of Lake Michigan, and our guide pointed out a number of
rock reef areas that are above the water line. These tiny rock islands have only become exposed in the nine years he has guided in the area.
Talking to him reminded me of an article I had read a couple of years ago about water draining out of the Great Lakes through a channel dredged in the
St. Clair River by the Army Corps of Engineers in the 1960's. I tracked some info down. This addresses specifically water levels in Lake Michigan
and Lake Huron. Lake Superior is connected to Lake Huron by the St. Mary's River, so maybe this is a contributing factor. It's like a drain in a

TORONTO, Can. -- Lakes Michigan and Huron have permanently lost a foot of water because of erosion in the St. Clair River caused by dredging and other
man-made meddling, according to a recently-released study.
Water is permanently being sucked from Lakes Huron and Michigan because of ongoing erosion caused by dredging and other human activities in the St.
Clair River -- the drain that funnels water out of the lakes -- according to a study.
If the data are accurate, the lakes may have already lost 12 inches of water in addition to natural lake level fluctuations. The data would also help
explain the low water levels that have plagued boaters and beachfront landowners during the last few years.
