Name: Wisconsin Well Data
Creator: DrillerDB

Every dot on this map is a real well. We pulled all 872,087 Wisconsin well-construction records - depth, water level, yield, and county - and drew the state with them. Brighter means more wells; color is how deep they go.

Distinct drilling companies on record

The median depth across all Wisconsin borehole records is 121 ft, with half falling between 70 and 188 ft. These cover every borehole filed with the state - water wells alongside monitoring wells, soil borings and decommissioning reports - so this is a broader population than water wells alone. Numbers here come straight from filed construction reports - not a model.

How deep Wisconsin wells go

Each bar is the share of records finished at that depth (20-ft bins). Half of all Wisconsin records fall between 70 and 188 ft.

Wisconsin well questions

How deep are wells in Wisconsin?

The median depth across Wisconsin borehole records is 121 ft, based on 509,142 records with a reported depth. Half fall between 70 and 188 ft. Depth varies a lot by county - from about 61 ft in the shallowest counties to over 243 ft in the deepest. These records cover every borehole filed with the state - water wells alongside monitoring wells, soil borings and decommissioning reports - so this is a broader population than water wells alone.

What is the water table depth in Wisconsin?

The median static water level (the depth to standing groundwater) across Wisconsin records is about 32 ft. It is usually much shallower than the finished well depth, because wells are drilled past the water table to reach a dependable aquifer.

How many well records does Wisconsin have?

DrillerDB holds 872,087 Wisconsin well records - part of an 18-million-record national database built from state well-construction reports. Wisconsin has required a well construction report for every new well since 1936.

How do I look up a specific address or well in Wisconsin?

Use the free water table depth lookup to see typical depth and water level at any address, or open the interactive well map to browse individual well records near a location.
