Re: Holy Water Levels, Again.
I like these profile maps of the great lakes. This one shows the dams, which is kind of neat, there really aren't that many on the Great Lakes system itself, most are in tributaries leading into the St Lawrence system, like the Ottawa river.
The folks who were saying the dams are having an impact on the Thousand Islands area may have a point. The first dam after Lake Ontario, Iroquois, is basically right at the east end of the 1000 Islands and is a water level control dam.
However, there really aren't any dams that should effect water levels on Erie, Michigan or Huron. The big drop is Niagara Falls, the Niagara River isn't really dammed in the conventional sense. Basically there are sluice ways that divert water from the upper Niagara River around Niagara Falls to a big man made reservoir and then down through generating turbines, but this system is a diversion, its not really impeding the flow of the Niagara river or the lakes above it.
I added the red dot using paint to illustrate roughly where Montreal is on the system.
