Skamania County, WA Water Table Trend
Skamania County, WA: the closest actual trend
Multnomah County, OR, 40 miles from Skamania County, is the closest county with a qualifying well, and its water table is holding roughly steady.
No well inside Skamania County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Skamania County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Multnomah County, OR'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.
