Wells in Jefferson County: depth and water level from 6,590 state well logs

The Wisconsin Department of Natural Resources has 6,590 logs for new and replacement private drinking water wells in Jefferson County, which includes Jefferson. The median well among them is 142 feet deep.

Typical depth
142 ft
median of 6,303 logs

Water level

Limits: well logs cover drilled wells reported to the state, not every well. Older and hand-dug wells are often missing, depths are as each driller reported them, and a county figure says nothing certain about one lot.
