Wells in Winnebago County: depth and water level from 7,907 state well logs

The Wisconsin Department of Natural Resources has 7,907 logs for new and replacement private drinking water wells in Winnebago County, which includes Oshkosh. The median well among them is 145 feet deep.

Typical depth
145 ft
median of 7,284 logs
Depth range
88 to 299 ft
10th to 90th percentile
Water level
27 ft
median, below ground, 6,536 logs
Years drilled
1988 to 2022
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.
