In the lower peninsula, Lakes Michigan and Huron have varied widely in depth in the 30 years that we have lived here. My husband's uncle used to have a cottage on Grand Traverse Bay (north of Traverse City) until a couple of years ago. I can remember years that we would have to walk maybe 50 yards to reach the water from the waterfront cottage. Those years, the boat hoist for their small fishing boat needed to be way out in the water. On the other hand, I can remember one year that the water nearly reached one of the bedrooms on the cottage. That was the scariest year, when the water level was so high that they were afraid that the cottage might be washed away, especially during storms. We learned to deal with those water level changes over the years.
Most of the docks that I've seen, especially in the inland lakes of the lower peninsula are taken out in the fall & put back in in the spring, allowing for adjustments in the water level, etc. It sounds like that the docks in Lake Superior may have to be moved this year, for the first time?
Water level changes, at least here in the Lower Peninsula, have been a fact of life as long as we have lived here. It sounds like many may have gotten used to the apparently relatively constant levels of Lake Superior, so it comes as a surprise. I have heard stories that Lake Superior's water level changes might actually be related, at least in part, to the Soo Locks & the St Mary's River, & how much water is pumped in & out of Superior with the locks, etc?
