Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
There are a few reports on Great lakes wind potentials. A recent one from the State of Michigan gave their offshore potential as 131 GW - but that involved the use of deep turbine foundations (spars, jack-up rigs), since Lake Michigan's average depth is about 200 to 300 meters.

Of course, the real answer is the wind potential is often a function of what price you can get for the electricity. Trying to compete with an old polluting coal burner like the one near Ludington is hopeless (less than 4 c/kw-hr production cost). That's a big hurdle to get over. States like Michigan are pretty hooked on supercheap coal based electricity. Besides, Michigan is over 180 meters above sealevel - raising ocean waters by 20 to 40 meters is not immediately their problem......

Anyway, another source of information on Great Lakes wind potential can be found at http://www.greengold.org/wind/engineer.html ---> "A Great Potential". For 0 to 20 meters, maximum potential is about 150 GW, and for the 0 to 40 meter depths, about 250 GW. It's definitely enough to power up the US North Coast/Canadian South Coast.

One of these days I should update it.
