Parker County, TX Water Table Trend
Parker County, TX: the closest actual trend
Johnston County, OK, 125 miles from Parker County, is the closest county with a qualifying well, and its water table is declining at a typical pace for a declining county.
No well inside Parker County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Parker County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Johnston County, OK'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.
