Grayson County, KY: the closest actual trend
Hardin County, KY, 27 miles from Grayson County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.

Worth checking your own well's depth log against it rather than assuming it matches. See Hardin County, KY'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.
