My father worked on the construction of the Blue Ridge Dam. The original plan was to drill the tunnel all the way through to the bottom of the Mogollon Rim. They drilled test wells along the route so they could know what was in the path of the tunnel. They abandoned the tunnel plan and put in pumps and a power station, because of too much underground water. They hit water in the last well they drilled. They put in a big pump and pumped out hundreds of gallons of water a minute for 24 hours and didn't lower the water table, at all. My dad doesn't know if they capped the well or filled it in.
Perhaps the people working on getting water should investigate this source.
