Harris County, GA Water Table Trend
Harris County, GA: the closest actual trend
Chattahoochee County, GA, 28 miles from Harris County, is the closest county with a qualifying well, and its water table is declining faster than most declining counties.
No well inside Harris County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Harris County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Chattahoochee County, GA'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.
