Calhoun County, AL: the closest actual trend
Cullman County, AL, 65 miles from Calhoun County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.
No well inside Calhoun County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Calhoun County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Cullman County, AL'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.
