New York well logs
Every time a well is drilled in New York, the driller files a completion report — the well log — with the New York State Department of Environmental Conservation water well completion reports. We hold 144,499 of them and rebuild this index weekly, so you can find one by address instead of by record number.

Well logs are filed by location, not by house number. Enter any New York address and we'll pull the recorded wells around it — essentially every New York well record (over 99.9%) carries a mapped location, and the DEC describes those positions as accurate to the parcel - good enough to tell which property a well sits on, though not the exact spot in the yard. The records carry no street address, so wells are found by location rather than by house number.

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 144,499 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 NYSDEC copy of the filed log itself. | 144,499 (100%) | |
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 144,498 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 142,780 (99%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 51,127 (35%) |
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.

Where these records come from
All of it is public record from the New York State Department of Environmental Conservation's water well completion reports, which registered well drillers have been required to file since 2000 (dec.ny.gov/environmental-protection/water/water-quantity/water-well-contractor-program). We don't hold anything the state doesn't publish. More on that database and what a filed record carries: NYSDEC 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 NYSDEC water well completion reports; depths 0-5,000 ft).
Common questions
Yes. New York drillers are required to file a completion report for each well, and those reports are kept by the New York State Department of Environmental Conservation water well completion reports. 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 — essentially every New York well record (over 99.9%) carries a mapped location, and the DEC describes those positions as accurate to the parcel - good enough to tell which property a well sits on, though not the exact spot in the yard. The records carry no street address, so wells are found by location rather than by house number. Each one shows its depth, static water level, tested yield, and a link to the original filed log.
Coverage varies: older wells were often never filed at all, 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.
