Ohio County, IN: the closest actual trend
The closest qualifying well to Ohio County is 14 miles away in Gallatin County, KY, where the trend runs rising, getting shallower over time.
Ohio County itself has no monitoring well with enough history to call its own trend, so treat this as a regional estimate, not Ohio County's own number. If you own a well here, comparing your own depth log against this regional figure is worth doing before assuming either way. See Gallatin County, KY'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.
