Not quite sure the difference, but there is an "aquifer" which is under the midwest and spans like 10 or so states, so that it is easily as large as some of the larger above ground inland seas. I can't remember the name of it, but someone had a link about it here a month or so ago (NK perhaps?) in another topic.

Aquifers, as I understand it, flow through the ground itself, usually flowing through sedimentary or porous layers of rock or ground and trapped in between denser layers of rocky material.

I would think, theoretically, that if an aquifer ran into a large, cavernous hole in the porous and upper-rocky material (while still being trapped on the lower bound up by dense rocky material) that it would expand to fill the cavernous space, thus creating an underground freshwater sea.
