Will County, IL: the closest actual trend
Kankakee County, IL, 22 miles from Will County, is the closest county with a qualifying well, and its water table is declining, slower than most declining counties.

Worth checking your own well's depth log against it rather than assuming it matches. See Kankakee County, IL's full page. See the no-data guide for why a county this close to a qualifying well still doesn't get its own number.
