Inside Illinois’s public well records
ILWATER records explicitly classified as private, semi-private or household/livestock water wells. Engineering borings and unclassified or other-use records are excluded; historical locations and missing fields vary.
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 |
|---|---|---|---|---|---|
| 122013296000 ↗ | Winnebago | Private Water Well | Status not reported7-44N-2E | 50 ft | 10 GPM |
| 122013247800 ↗ | Winnebago | Private Water Well | Status not reported7-44N-2E | 76 ft | 30 GPM |

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.
How to verify a Illinois record
Check the ILWATER well identifier and private/semi-private/household classification. Engineering borings and other-use entries are excluded from this lookup; confirm any construction values in the original record.
Open Illinois ILWATER Private Water Wells ↗ and search for the identifiers above. Compare the original filing, location method and well type with seller documents and a physical well identifier.
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
Illinois ILWATER Private Water Wells
Illinois State Geological Survey / Prairie Research Institute
ILWATER records explicitly classified as private, semi-private or household/livestock water wells. Engineering borings and unclassified or other-use records are excluded; historical locations and missing fields vary.
What you can find in Illinois well records
Available fields vary by individual filing, but the Illinois integration can surface:
- mapped location
- well depth
- construction details
How to search the Illinois well map and read a well log
- Enter the full property address above to locate the property and open nearby mapped records.
- Compare record identifiers, well type, completion date and distance before deciding which wells are relevant.
- Open the public source below to trace an original well log or completion report where the agency publishes one. A mapped summary may omit details from that document.
- Verify the actual property well with the seller, record identifiers and an on-site inspection; nearby records alone cannot identify it.
How to use the record before buying a property
Use the public record as a starting point, then verify important property decisions against the original source and current on-site conditions.
Start with the address search, compare the closest records and their distances, then open the public source before treating a record as the subject property's well. If water quality or current performance matters, use current testing and an on-site well inspection.

Public Illinois source
WellLookup is independent of Illinois State Geological Survey / Prairie Research Institute. The underlying public source is Illinois ILWATER Private Water Wells. WellLookup adds address search, nearby-record comparison and property-focused reporting; it preserves the published source values.
Frequently asked questions
Yes. Enter a street address and WellLookup will search nearby mapped records from the supported Illinois source.
Not necessarily. Location precision varies, so verify identifiers, documents and the physical well before relying on the match.
The $29.99 USD property report organizes the available evidence, nearby comparisons, source limitations and follow-up questions into one PDF.
