How Deep Are Wells in Michigan? Real Depth Data by County
"How deep will my well need to be?" is one of the hardest well-drilling questions to answer in the abstract, because it depends entirely on local geology. Michigan publishes its driller's completion reports as open data, so instead of a national average, here is what 198,146 actual residential wells drilled since 2011 report for depth, broken down by county.
Source and method: Michigan Department of Environment, Great Lakes, and Energy (EGLE) Wellogic statewide water-well database (Michigan GIS Open Data), extracted 2026-07-14. Figures include only wells recorded as residential (domestic) use, completed 2011 or later, with a reported depth between 15 and 2,000 ft (to exclude likely data-entry errors). A county is shown only if it has at least 5 qualifying reports. The depth shown is the reported total well depth. EGLE notes Wellogic is not a complete record of every well in the state (well inclusion before 2000 varies by county) and the driller-submitted reports are not independently verified. These are figures self-reported by licensed drillers to the state; neither the Michigan Department of Environment, Great Lakes, and Energy (EGLE) nor this site independently verifies them. Treat this as a planning reference, not a guarantee for any specific property, your own site could sit well outside your county's typical range.
Median well depth by county
"Typical range" is the 10th-to-90th-percentile band, i.e. where 80% of reported wells in that county fell. Counties with fewer than 5 qualifying reports since 2011 are omitted rather than shown with a misleading precise figure.

How to use this table
Find your county, then use the median and typical-range figures as a starting point when budgeting with the well drilling cost estimator or reading the cost guide. A driller working in your county day-to-day will still know more about your specific property than a county-wide figure can, ask them how your site compares to the county's typical range, and why, before you commit to a per-foot quote with no depth ceiling.
We build these tables state by state from each state's public completion-report data. See also our Texas well depth by county page.
