Indiana well logs
Every time a well is drilled in Indiana, the driller files a completion report — the well log — with the Indiana Department of Natural Resources Division of Water water-well record database. We hold 414,953 of them and rebuild this index weekly, so you can find one by address instead of by record number.

Heads up: we re-read IDNR weekly and hold every record it publishes, but the newest filed log in the source itself is from 2018. A well drilled since then very likely has no log here yet — that's the state's publishing cadence, not a gap in our copy. Everything below describes the 414,953 records that do exist.
Well logs are filed by location, not by house number. Enter any Indiana address and we'll pull the recorded wells around it — wells are plotted from the coordinates the Indiana DNR recorded for each well — field-located or office-geocoded on most records, estimated (PLSS/TRS) on others; county-centroid-only records are shown without a map point.

Not every filed report carries every field — older logs are thinner, and what the state captured changed over the decades. This is the actual coverage across all 414,953 records, so you know what to expect before you look anything up.
| Field | What it tells you | Records with it | Coverage |
|---|---|---|---|
| Original log document | A direct link to the IDNR copy of the filed log itself. | 414,953 (100%) | |
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 411,522 (99%) | |
| Total depth | How deep the hole was drilled, in feet. | 397,682 (96%) | |
| Date completed | When the well was finished and the log filed. | 395,760 (95%) | |
| Static water level | How far below the surface the water stood at rest. | 361,979 (87%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 311,315 (75%) |
When Indiana's wells were drilled
Dated logs by decade of completion (395,757 of 414,953 records carry a usable completion date). The shape of this chart is mostly the history of the filing requirement, not of drilling — thin early decades mean the logs weren't kept, not that nobody drilled.
| Decade | Logs filed | |
|---|---|---|
| 1900s | 352 | |
| 1910s | 272 | |
| 1920s | 532 | |
| 1930s | 1,330 | |
| 1940s | 4,089 | |
| 1950s | 14,234 | |
| 1960s | 67,666 | |
| 1970s | 61,587 | |
| 1980s | 49,734 | |
| 1990s | 105,957 | |
| 2000s | 76,411 | |
| 2010s | 13,593 |
Three ways to find a well log here
- By address — the free lookup maps an address to the wells recorded around it. This is what most people want: "how deep is the well on the place I'm buying."
- By county — each county page carries the median depth, water level and yield computed from every log filed there, plus the drillers working it.
Well logs by county
Where these records come from
All of it is public record from the Indiana Department of Natural Resources Division of Water's water-well record database — the state's repository of filed well records (www.in.gov/dnr/water). We don't hold anything the state doesn't publish. More on that database and what a filed record carries: IDNR well records. What we add is that the records are indexed by location, the statistics are computed the same way in every county, and the whole thing is refreshed weekly. Our filters and the exact computation are on the methodology page (statistics use filed water-well records from the Indiana DNR Division of Water (the public dataset carries no well-use code, so all records are included); depths 0–5,000 ft).
Common questions
Yes. Indiana drillers are required to file a completion report for each well, and those reports are kept by the Indiana Department of Natural Resources Division of Water water-well record database. Anyone can look them up. This site is an independent index of that public record — we re-read the source and recompute every page weekly.
Well logs are filed by location, not by street address, so you search the map rather than a house number. Enter the address on our free lookup and you'll see the recorded wells around that spot — wells are plotted from the coordinates the Indiana DNR recorded for each well — field-located or office-geocoded on most records, estimated (PLSS/TRS) on others; county-centroid-only records are shown without a map point. Each one shows its depth, static water level, tested yield, and a link to the original filed log.
The oldest dated log in our copy was completed in 1900; the newest is from 2018. Coverage thins out the further back you go — older wells were often never filed, and filing requirements tightened over time.
Most likely it was never filed. Wells drilled before the state's reporting requirement — and hand-dug or unpermitted wells — have no log at all. It also happens that a log exists but its recorded location is off, in which case it will show up under a neighboring property. Neither is something we can fix from the source data, and we'd rather say so than invent a record.
The useful parts for a buyer or a homeowner: how deep the well is, how high the water stands in it, how many gallons per minute it produced when tested, what the driller hit on the way down, and who drilled it. Together those say whether the well is likely to keep producing and what a replacement would cost.
The property report pulls every recorded well near an address — depths, water levels, yields, drillers , and links to each original filed log — as one printable summary for due diligence.
