Well depth
How deep are wells in ZIP 59064?
Of 182 wells with a recorded total depth, the median is 60 feet. Half were drilled between 33 and 120 feet; one in ten went deeper than 219 feet and one in ten found water shallower than 27 feet. Depth is set by local geology and position on the landscape, both of which change over short distances, so the spread matters as much as the median.
Static water level
20 ft
median depth to water at rest · half between 13 and 36 ft
The static level is how far below ground the water stands before pumping, measured by the driller at completion. It affects pump setting and operating cost, and it moves with season and with neighbouring use.
Well yield
12 gpm
median tested yield · half between 5 and 24 gpm
20% of tested wells produced under 5 gallons per minute and 33% produced 20 or more. These are short completion tests, not sustained-capacity tests; a household typically needs 3 to 5 gpm with storage.

Area totals describe the neighbourhood, not any one parcel. Montana publishes no authoritative link between a parcel and a water right; whether a right attaches to a specific property is a property-level question that our reports answer with the DNRC abstract linked.
Aquifers and geology
What wells in ZIP 59064 draw from
Drillers record the aquifer a well is completed in. The units below account for the wells here that carry an aquifer assignment; the median depth beside each is for wells completed in that unit.
- Alluvium (holocene)72 wells · 51% · median 40 ft
- Bearpaw Shale28 wells · 20% · median 115 ft
- Lance Formation19 wells · 13% · median 128 ft
- Alluvium (pleistocene)5 wells · 4% · median 25 ft
Aquifer assignments are the driller's, recorded at completion, and many older logs carry none. Absence of an assignment is not evidence about the geology.

A documented release or site in the area is not evidence that any particular well is affected. Whether a release reaches a well depends on groundwater flow direction, geology, well depth and construction, the extent of the plume and the cleanup performed. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
