It has been several decades since my studies of isostatic rebound, but as I remember, what is happening is that the rebound further south is pretty much done in comparison to further north. The result is the land is slowly tilting with areas to the north getting higher which tends to drain Huron more. Not saying that dredging has not had an impact, but if it did have a huge impact then Erie would be much fuller than it is.
Back home on Lake Ontario after something over 36,000 nm circumnavigator. Not surprisingly there is a lot of stuff I want to get done on Ainia both cosmetically and functionally. Getting an early start so it will be ready to go for next summer (Lake Superior?).
