The closest qualifying well to Ashtabula County is 36 miles away in Geauga County, OH, where the trend runs holding roughly steady.
Ashtabula County itself has no monitoring well with enough history to call its own trend, so treat this as a regional estimate, not Ashtabula 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 Geauga County, OH'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.
