Well depth
How deep are wells in ZIP 59312?
Of 165 wells with a recorded total depth, the median is 171 feet. Half were drilled between 114 and 220 feet; one in ten went deeper than 337 feet and one in ten found water shallower than 80 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
70 ft
median depth to water at rest · half between 40 and 115 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
10 gpm
median tested yield · half between 5 and 15 gpm
10% of tested wells produced under 5 gallons per minute and 19% 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 59312 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.
- Fort Union Formation14 wells · 61% · median 186 ft
- Fox Hills-hell Creek Aquifer5 wells · 22% · median 600 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.
