Fergus County, MT Water Table Trend
Fergus County, MT: the closest actual trend
Meagher County, MT, 91 miles from Fergus County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.
No well inside Fergus County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Fergus County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Meagher 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.
