Depth of the water table?

I was unsuccessful in using the web to get a map of water table depths in Chicago. I would like to know where this information can be found. An accuracy of 3 feet would be fine.

You'd think that the US Geological survey would be you're best source?

Note that this depends on your own local geography -- and not just surface geography. And these days it also depends on how much humans have been disrupting natural water flow. I'd suggest you ask your local town government, and/or local well-digging businesses... or the geology department of a nearby college. They're the ones who are mostly likely to know what's happening in your neighborhood.
