Washington County, ID Water Table Trend
Washington County, ID: the closest actual trend
Gem County, ID, 33 miles from Washington County, is the closest county with a qualifying well, and its water table is holding roughly steady.
No well inside Washington County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Washington County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Gem County, ID'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.
