How deep are wells in Michigan? Depth by county from 1,082,337 state well logs

The Michigan Department of Environment, Great Lakes, and Energy (EGLE) keeps the logs drillers file for household water wells. Across the 1,078,996 that give a depth, the median Michigan well is 94 feet deep, and the middle 80% run from 45 to 204 feet. 83 of 83 counties have 30 or more logs and appear in the table.

Every Michigan county with 30 or more logs

Depth is the total depth the driller reported. "Middle 80%" is the 10th to 90th percentile: one log in ten is shallower than the first number and one in ten deeper than the second. Water level is the median static water level (how far below the ground the water stood when the well was finished), from the logs that record one. Years: the span of the middle 90% of dated logs.

Method

  • Source: the Michigan Department of Environment, Great Lakes, and Energy (EGLE), Wellogic statewide water well database (Michigan Wellogic Wells open data layer). We downloaded it on October 10, 2026 from the state's own server.
  • Rows counted: household water wells. Field filter as run: WELL_TYPE = HOSHLD; depth = WELL_DEPTH unless DEPTH_FLAG is set; level = SWL unless SWL_FLAG is set, 999.99 or a flowing well.
  • Each log is placed in the county the state file gives, matched to Census county names. 1,082,337 logs matched a Michigan county.
  • A depth outside 1 to 5,000 feet is treated as a typing error and left out. A water level counts only when it is above zero and shallower than the well's depth. Medians and percentiles use the standard linear method.
  • A county shows figures only with 30 or more logs that give a depth (water level: 30 or more levels). Nothing is estimated or filled in.

Limits

  • Well logs cover drilled wells that a driller reported to the state. They are not a count of every well: older wells, hand-dug wells and wells from before reporting began are often missing.
  • Depths and water levels are as each driller wrote them on the day the well was finished. Water levels move with season, drought and nearby pumping, so an old reading is not today's level.
  • Dates vary by county. The years column shows when most of the logs were drilled; a county with mostly older logs describes older wells.
  • A county figure says nothing certain about one lot. Depth can change a lot across a county, from hilltop to valley. A local driller's logs for nearby wells are the better guide for a single property.
