The Great Lakes states have an agreement surrounding how much water you can remove from the lakes. That would be your first regulatory hurdle. In addition I suspect the loss associated with an aqueduct of that scale would make desalinization more efficient, which is generally cost prohibitive at current water levels.

The water pact is even more specific in that at least WI I believe you have to be East of the subcontinental divide to pull water from Lake Michigan.

Another poster mentioned real estate peaking in a zip code of AZ for having limited access to fresh water. I wonder how long until real estate along the great lakes starts becoming a long term hedge.

We also have a treaty with Canada about the usage of water from the Great Lakes.

We Canadians have seen how much value the US administration places on treaties.
