Look at answer 4. So the water levels have been changing for 200 years/ Hmmm....

4. Are sea levels rising?

Yes. Sea levels have been rising at a rate of about 3.3 mm a year since 1993, when satellite altimeters began tracking the data. Tidal gauging records, which vary from region to region, indicate a steady rise in sea levels of about 1.7 mm a year since 1870, which fits in with an overall trend stretching back over 200 years.

I saw a PBS show on why Lake Erie's level has been changing. The first blame went to humans. However they now scientifically speculate rebound. The Great Lakes were formed by glaciers and the massive weight compressed the Earth. The lake is naturally emptying itself. That is the modern thinking. Ten years from now they my change the ideas. This is why I see no need for rash decisions.
