New Hampshire Well Data · NHDES
NHDES well records, searchable by address
Every New Hampshire well log is filed with the NHDES Water Well Inventory. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 106,477 of them and rebuild the index weekly, so you can start from an address instead.

Enter any New Hampshire address and we return the wells recorded around it — New Hampshire records the well's own street address on nearly every report and the tax map and lot on four wells in five, so a well can usually be matched to its property — though the mapped point itself may be placed from the address or lot rather than surveyed at the 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 106,477 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. | 106,477 (100%) | |
| Original log document | A direct link to the NHDES copy of the filed log itself. | 106,477 (100%) | |
| Date completed | When the well was finished and the log filed. | 106,476 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 106,425 (100%) | |
| Street address | A street address on the filed report (varies a lot by state and era). | 106,091 (100%) | |
| Drilling method | Rotary, cable tool, auger, and so on. | 105,969 (100%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 103,429 (97%) | |
| Static water level | How far below the surface the water stood at rest. | 63,498 (60%) |
How this differs from going to NHDES directly
Nothing here replaces the official record, and for a single well you already have the record number for, NHDES is the place to go (www.des.nh.gov/water/drinking-water-and-wells). 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. New Hampshire records the well's own street address on nearly every report and the tax map and lot on four wells in five, so a well can usually be matched to its property — though the mapped point itself may be placed from the address or lot rather than surveyed at the 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.
- The original is always one click away. 106,477 of our records carry a direct link to the NHDES copy of the filed log itself.

Common questions
With NHDES — the NHDES Water Well Inventory. Every New Hampshire 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.des.nh.gov/water/drinking-water-and-wells.
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, New Hampshire records the well's own street address on nearly every report and the tax map and lot on four wells in five, so a well can usually be matched to its property — though the mapped point itself may be placed from the address or lot rather than surveyed at the wellhead.
No, and it is not meant to be. This is an independent index built from the data NHDES publishes, rebuilt weekly. Every well we show links back to its own NHDES record, so you can always open the original filed log. If our copy and the state's ever disagree, the state's is right.
Our current copy holds 106,477 records across 10 counties, with completion dates from 1900 to 2026. That is everything NHDES publishes in its bulk record set as of 2026-08-23. 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 NHDES 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 , and links to each original filed log — as one printable summary for due diligence.
