Seepage.
Water seeps into the Great Lakes from underground springs and water tables. These lakes were "dug out" by glaciers and then filled up by ground water.
There are no substantial rivers emptying into the Great Lakes. The water seeps in from groundwater.

It looks like Lakes Michigan & Huron are at the same elevation. Downstream of that, Lake St. Clair, the Detroit River & Lake Erie are within 10' of elevation of Lake Michigan, with no locks/dams in the way before Niagara Falls.

Illegal immigrants fill it up with buckets. It stays there because it's afraid of Lake Huron.
