Well depth
How deep are wells in ZIP 59319?
Of 109 wells with a recorded total depth, the median is 60 feet. Half were drilled between 40 and 100 feet; one in ten went deeper than 152 feet and one in ten found water shallower than 30 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
28 ft
median depth to water at rest · half between 19 and 50 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 18 gpm
11% of tested wells produced under 5 gallons per minute and 25% 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 59319 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.
- Hell Creek Formation31 wells · 44% · median 100 ft
- Alluvium (quaternary)16 wells · 23% · median 38 ft
- Fox Hills-hell Creek Aquifer13 wells · 18% · median 220 ft
- Fox Hills Formation Or Sandstone6 wells · 8% · median 73 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.
