Wellogic well records, searchable by address

Every Michigan well log is filed with Wellogic, the statewide groundwater database maintained by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). Those records are public, but they are organized by mapped location and record number — not by street address. We hold 1,145,689 of them and rebuild the index weekly, so you can start from an address instead.

What a Wellogic record contains

Not every filed report carries every field — older records are thinner, and what the state captured changed over the decades. This is the real coverage across all 1,145,689 records, so you know what to expect before you search.

How this differs from going to EGLE directly

Nothing here replaces the official record, and for a single well you already have the record number for, EGLE is the place to go (www.michigan.gov/egle/about/organization/drinking-water-and-environmental-health/wellogic). What this site adds is the part that is hard from the source data:

Common questions

Where are Michigan well logs officially filed?

With Wellogic — Wellogic, the statewide groundwater database maintained by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). Every Michigan driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is www.michigan.gov/egle/about/organization/drinking-water-and-environmental-health/wellogic.

Can I search Wellogic by street address?

Not directly — well records are filed against a mapped location and a record number, not a mailing address, which is the single most common reason people give up on the search. That is exactly the gap this site fills: enter an address on our free lookup and we return the recorded wells around that point, wells are plotted from the location recorded in Wellogic — typically the reported street address with driller-keyed coordinates; about 99% of records carry a street address.

Is this the official Wellogic record?

No, and it is not meant to be. This is an independent index built from the data EGLE publishes, rebuilt weekly. For the authoritative copy of any single record, go to EGLE directly. If our copy and the state's ever disagree, the state's is right.

How many Michigan well records are there?

Our current copy holds 1,145,689 records across 83 counties, with completion dates from 1872 to 2026. That is everything Wellogic publishes in its bulk record set as of 2026-08-13. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.

Does it cost anything?

Searching by address here is free, the same as searching Wellogic is free. What we charge for is the compiled property report — every recorded well near one address, with the statistics and the original log links, as one printable document for a sale or a loan file. That is $29.
