I think the Aral sea was particularly vulnerable because almost all of its water was supplied from only a couple rivers. I don't think the Great Lakes would be so easily choked off, especially on the northern end of them where they blend into the Canadian Shield which is unusable for agriculture (it's mainly just granite) and so irrigation projects taking the water from there would be less likely.
Then a few decades later, the US will have its very own Aral Sea.
That particular cynicism aside, what will probably happen is that sufficient global warming will make the desert actually uninhabitable and people will migrate to the Great Lakes.
