Well depth
How deep are wells in ZIP 59934?
Of 281 wells with a recorded total depth, the median is 190 feet. Half were drilled between 120 and 320 feet; one in ten went deeper than 480 feet and one in ten found water shallower than 75 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
71 ft
median depth to water at rest · half between 27 and 140 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
25 gpm
median tested yield · half between 12 and 40 gpm
5% of tested wells produced under 5 gallons per minute and 64% 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 59934 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.
- Belt Supergroup91 wells · 54% · median 320 ft
- Glacial Drift60 wells · 36% · median 156 ft
- Ravalli Group6 wells · 4% · median 162 ft
- Siyeh Limestone (of Piegan Group)5 wells · 3% · median 220 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.
