OhioWell Data
Every dot on this map is a real well. We pulled all 872,000 Ohio 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 Ohio well is 89 ft deep; the average is a bit higher (about 143 ft), pulled up by a long tail of very deep wells in the Driftless Area and the Door Peninsula. Numbers here come straight from filed well-construction reports - not a model.
How deep Ohio wells go
Each bar is the share of wells finished at that depth (20-ft bins). Most Ohio wells land between 40 and 200 ft.
Well depth & water by Ohio county
72 of Ohio's 88 counties - those whose well records carry confidently geolocated coordinates, ranked by number of wells on record. Median depth, median static water level, and median tested yield for each - real figures, computed from every filed report we hold.

A century of Ohio wells
Ohio has required a well construction report for every new well since 1936, and DrillerDB's records reach back to the 1930s. Wells drilled per decade:
Ohio well questions
How deep are wells in Ohio?
The median water well in Ohio is 89 ft deep, based on 867,476 records with a reported depth. Half of all wells fall between 61 and 131 ft. Depth varies a lot by county - from about 40 ft in the shallowest counties to over 221 ft in the deepest.
What is the water table depth in Ohio?
The median static water level (the depth to standing groundwater) across Ohio 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 Ohio have?
DrillerDB holds 872,000 Ohio well records - part of an 18-million-record national database built from state well-construction reports. Ohio has required a well construction report for every new well since 1936.
How do I look up a specific address or well in Ohio?
