Story County, IA Water Table Trend
Story County, IA: the closest actual trend
Marshall County, IA, 25 miles from Story County, is the closest county with a qualifying well, and its water table is declining, slower than most declining counties.
No well inside Story County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Story County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Marshall County, IA'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.
