Inside Washington’s public well records
Ecology well reports include mapped location, depth, completion date, well type, static water level and flow where available; many locations are approximate to PLSS survey units.
These are retrieved public records, shown so you can see the identifiers, available values and gaps before running your own lookup. They are regional examples, not a statewide sample or a prediction for a property.
| Public record ID | Published locality | Published use / type | Status / location quality | Recorded depth | Reported rate |
|---|---|---|---|---|---|
| 968354 | Spokane | Decommissioning | Status not reportedLocation quality not reported | 40 ft | Not reported |
| 968349 | Spokane | Soil Boring | Status not reportedLocation quality not reported | 40 ft | Not reported |
| 968339 | Spokane | Soil Boring | Status not reportedLocation quality not reported | 35 ft | Not reported |
Depths are converted from the lookup’s normalized meters to feet. Reported rate can represent yield, a pump-test rate or pump capacity depending on the source; these values are historical and are not interchangeable. A source zero can be a placeholder or a reported result: verify its meaning in the original file. “Not reported” means no comparable value was retained, not zero and not proof that the original file lacks all information.
No comparable reported rate is available in these examples; a supply estimate cannot be calculated from them.
How to verify a Washington record
Use the well tag and Ecology report identifier, then read the project and work-completion information. Survey-based locations can be approximate, and report receipt is not the construction date.
Open Washington State Well Reports ↗ and search for the identifiers above. Compare the original filing, location method and well type with seller documents and a physical well identifier.
What the published index contains
On October 23, 2026, the public layer returned 1,193,525 rows. Of those, 1,193,495 had a non-empty value in CompletedDepth.
These are unfiltered layer-row counts, including the record types and repeat filings published by the agency. They are not a count of unique domestic wells, a completeness estimate, or a check of current well condition.
Review method: up to three distinct public identifiers selected in returned distance order from an existing regional lookup, without selecting for an attractive depth or yield. Re-run the example lookup ↗ · How these reviews are prepared
Washington State Well Reports
Washington State Department of Ecology
Ecology well reports include mapped location, depth, completion date, well type, static water level and flow where available; many locations are approximate to PLSS survey units.
Washington well logs: check location accuracy
Start with the free address lookup. Official state records can help frame these questions, but they do not replace an inspection.
- Is the mapped location an actual wellhead or an approximate survey location?
- Can the Ecology well report or tag identify the well on the property?
- Do current water testing and flow measurements support the home's needs?
The optional $29.99 USD report organizes nearby records, coverage gaps and buyer follow-up questions in a four-page PDF.
Washington well reports: understand the limits of mapped locations
Washington Department of Ecology well reports contain historical construction and drilling information. Many older reports are located using public-land-survey descriptions; a mapped point can therefore be approximate and should not be treated as a precise wellhead location.
| Source field | What it means | What to verify |
|---|---|---|
| Well tag and source report | Tags and report links, where available, are better verification leads than a map marker alone. | Match the tag or original report to seller documentation and the physical well. |
| Township–range–section and county | These describe survey or geographic context for the record; they do not guarantee a surveyed parcel-to-well location. | Check how the original report locates the well before interpreting a short mapped distance. |
| Depth, completion date, static level and reported flow | These are historical filed values, and coverage varies by report and project type. | Arrange current water testing and a flow/recovery assessment for the subject property. |
Practical record-checking steps
- Search an address, note well tags, project type and any original Ecology report links.
- Check whether a location is based on a township–range–section reference or a more precise position.
- Use the original well report and on-site records to confirm identity before drawing conclusions about a property's supply.
Some historical locations were mapped from survey divisions rather than measured at the well. Proximity on the map does not by itself prove that a report belongs to a particular parcel.
Check the actual published record: Open the official state source ↗. Use the public identifiers in the examples above to trace the source. A nearby record alone does not confirm which well serves a property.

Washington coverage limitation
Washington Ecology notes that many historical well-report locations are approximate and may be represented by public-land-survey locations rather than an exact wellhead. WellLookup does not expose owner-name fields and does not treat proximity as proof that a record serves the searched parcel.
Public Washington source
WellLookup is independent of Washington State Department of Ecology. The underlying public source is Washington State Well Reports. WellLookup adds address search, nearby-record comparison and property-focused reporting; it preserves the published source values.
