What these numbers mean if you are buying here
A county median is a useful orientation, not a prediction for a specific property. Well depth in Montana is driven by local geology and topographic position, and both change over short distances — particularly at the edges of the intermontane basins, where unconsolidated basin fill gives way to bedrock. Two parcels a mile apart in Hill County can require very different wells.
The spread here shows that directly. While the median is 90 feet, recorded depths run from 5.3 to 1,914 feet. That range is why our property reports select comparable wells around the specific parcel and weight them by geology rather than quoting a county average.
The median reported yield in Hill County is 12 GPM. Bear in mind these are short drilling-test measurements taken at completion, not sustained-capacity tests, so treat them as an indication of what drillers encountered rather than a guarantee of long-term supply.
Static water level — the depth at which water stands before pumping — has a median of 30 feet across 2,515 records in the county. This affects pump setting and operating cost.
We have indexed 5,045 water-right records associated with Hill County from Montana DNRC. Whether any of them attach to a particular parcel is a property-specific question — Montana publishes no authoritative parcel-to-water-right link, which is why our reports label these as potential associations and link you to the original DNRC abstract.
