Missouri Well Data · MoDNR
MoDNR well records, searchable by address
Every Missouri well log is filed with the Missouri Department of Natural Resources water well database. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 195,527 of them and rebuild the index weekly, so you can start from an address instead.

Enter any Missouri address and we return the wells recorded around it — every Missouri well certification carries a mapped location. The state records a site address on fewer than a third of them — the address on most records is the owner's mailing address, not the well — so results show the records around a property rather than a single wellhead.

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 195,527 records, so you know what to expect before you search.
| Field | What it tells you | Records with it | Coverage |
|---|---|---|---|
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 195,450 (100%) | |
| Date completed | When the well was finished and the log filed. | 193,087 (99%) | |
| Driller | The licensed company that drilled the well and signed the log. | 192,629 (99%) | |
| Total depth | How deep the hole was drilled, in feet. | 192,363 (98%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 179,213 (92%) | |
| Static water level | How far below the surface the water stood at rest. | 164,460 (84%) | |
| Street address | A street address on the filed report (varies a lot by state and era). | 56,447 (29%) |
How this differs from going to MoDNR directly
Nothing here replaces the official record, and for a single well you already have the record number for, MoDNR is the place to go (dnr.mo.gov/water/business-industry-other-entities/permits-certification-engineering-fees/well-drilling). What this site adds is the part that is hard from the source data:
- An address is enough. You do not need a record number, a section-township-range, or a latitude to start. Every Missouri well certification carries a mapped location. The state records a site address on fewer than a third of them — the address on most records is the owner's mailing address, not the well — so results show the records around a property rather than a single wellhead.
- The neighbours, not just the well. Buyers and lenders care what depth and yield are normal nearby, which means reading many records at once, not one.
- The same statistics everywhere. Median depth, static water level and yield are computed identically in every county, so two counties can actually be compared. The exact filters are on the methodology page.

Common questions
With MoDNR — the Missouri Department of Natural Resources water well database. Every Missouri driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is dnr.mo.gov/water/business-industry-other-entities/permits-certification-engineering-fees/well-drilling.
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, every Missouri well certification carries a mapped location. The state records a site address on fewer than a third of them — the address on most records is the owner's mailing address, not the well — so results show the records around a property rather than a single wellhead.
No, and it is not meant to be. This is an independent index built from the data MoDNR publishes, rebuilt weekly. For the authoritative copy of any single record, go to MoDNR directly. If our copy and the state's ever disagree, the state's is right.
Our current copy holds 195,527 records across 115 counties, with completion dates from 1921 to 2026. That is everything MoDNR publishes in its bulk record set as of 2026-08-21. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.
Searching by address here is free, the same as searching MoDNR 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.
The property report pulls every recorded well near an address — depths, water levels, yields, drillers — as one printable summary for due diligence.
