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 Treasure County can require very different wells.
The spread here shows that directly. While the median is 80 feet, recorded depths run from 8 to 1,360 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 Treasure County is 10 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 763 records in the county. This affects pump setting and operating cost.
We have indexed 1,698 water-right records associated with Treasure 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.
