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 Ravalli County can require very different wells.
The spread here shows that directly. While the median is 105.5 feet, recorded depths run from 88 to 123 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 Ravalli County is 30 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 31.5 feet across 2 records in the county. This affects pump setting and operating cost.
