Yuba County, CA Water Table Trend
Yuba County, CA: the closest actual trend
Sutter County, CA, 25 miles from Yuba County, is the closest county with a qualifying well, and its water table is rising, getting shallower over time.
No well inside Yuba County clears this site's 15-year qualifying bar, so this is the closest real reading, not a measurement of Yuba County's own aquifer. Worth checking your own well's depth log against it rather than assuming it matches. See Sutter County, CA'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.
