Idaho County, ID Water Table Trend
Idaho County, ID: the closest actual trend
The closest qualifying well to Idaho County is 67 miles away in Ravalli County, MT, where the trend runs holding roughly steady.
Idaho County itself has no monitoring well with enough history to call its own trend, so treat this as a regional estimate, not Idaho 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 Ravalli County, MT'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.
