Rock County, WI Water Table Trend
Rock County, WI: the closest actual trend
Winnebago County, IL, 23 miles from Rock County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.
No well inside Rock County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Rock County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Winnebago County, IL'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.
