Well, look at it this way.... instead of an aquifer, you've got a nice, deep reservoir. Which'll also change the local microclimate to be cooler.
I'm afraid it isn't as minor as that. Look at the page I linked. San Antonio is at the 'bottom' of the aquifer. Literally. This would not only become a spring, but it would flood the San Antonio River all the way out to the coast until the aquifer is dry. Given how big of a hole it is, that won't take long in the grand scheme of things. It will definitely be noticed once the water pressure on the other artesian wells goes to nothing and the springs all dry up.
For perspective, here's the wikipedia article on the Comal Springs: http://en.wikipedia.org/wiki/Comal_Springs_(Texas)
Monorail? MONORAIL!
Actually, this could be what he was doing... though not a monorail, but a subway instead.
