Davis County, IA Water Table Trend
Davis County, IA: the closest actual trend
Schuyler County, MO, 20 miles from Davis County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.
No well inside Davis County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Davis County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Schuyler County, MO'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.
