No well inside St. Louis County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of St. Louis County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Itasca County, MN'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.
