Wells in Waukesha County: depth and water level from 23,711 state well logs

The Wisconsin Department of Natural Resources has 23,711 logs for new and replacement private drinking water wells in Waukesha County, which includes Oconomowoc. The median well among them is 146 feet deep.

Typical depth
146 ft
median of 23,002 logs

middle 90% of dated logs

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.
