Allen County, IN Water Table Trend
Allen County, IN: the closest actual trend
Whitley County, IN, 23 miles from Allen County, is the closest county with a qualifying well, and its water table is holding roughly steady.
No well inside Allen County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Allen County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Whitley County, IN'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.
