Clay County, KS: the closest actual trend
Riley County, KS, 24 miles from Clay County, is the closest county with a qualifying well, and its water table is holding roughly steady.

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