Nez Perce County itself has no monitoring well with enough history to call its own trend, so treat this as a regional estimate, not Nez Perce 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 Whitman County, WA'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.
