One of the best free resources before drilling a new well is the record of wells already drilled nearby. These logs can show what crews found below the surface and sometimes provide groundwater measurements. The trick is knowing how to use them without treating imperfect data as a guarantee.
Step 1: Locate your parcel accurately
Start with the assessor parcel number, legal description, coordinates or a reliable map pin. A vague town name is too broad for well research. Identify the relevant search area and look for recorded wells in similar terrain rather than only the closest point.
Step 2: Open the correct state tool
For Utah, use the Division of Water Rights Well Log Search. For Arizona, start with the ADWR Well Registry, where registration numbers often begin with 55-. Arizona also maintains a Groundwater Site Inventory for additional groundwater-level information.
Step 3: Separate the measurements
Total depth is how far the well was drilled. Static water level describes where water stood under a particular set of conditions. Reported production may reflect a specific test or drilling observation. These are different values, recorded at different times and levels of reliability.
Look at the construction date and reported geology, too. A very old water level may no longer represent current conditions.
Step 4: Build a range, not a single prediction
Review several relevant wells and identify what is consistent and what varies. Note missing records, substantial differences and changes across terrain. Ask a knowledgeable driller to interpret what the data means for your parcel and how much uncertainty remains.
A short worksheet to keep the research useful
Save the well identifier, record link and location alongside each set of measurements.
Record the drilling date and any water-level measurement date separately. A depth-to-water figure without a date needs extra caution.
Keep total depth, static water level and reported production in separate columns; mark missing values as unknown rather than zero.
Bring the original logs and a parcel map to your drilling discussion, not just a single average depth.
For Utah searches, the state well-information page provides location and map searches. In Arizona, a failed parcel search does not necessarily mean no well record exists: ADWR notes that parcel splits or combinations can leave registry information out of date. Its plotted locations may also represent a cadastral area rather than an exact wellhead, so check the underlying file before judging how close a well is.
Does a nearby well record mean I have permission to drill?
No. Geological evidence and legal authorization are separate questions. Verify water rights, permitting and applicable land-use requirements independently.
