Well depth

How deep are wells in ZIP 59316?

Of 156 wells with a recorded total depth, the median is 212 feet. Half were drilled between 161 and 311 feet; one in ten went deeper than 521 feet and one in ten found water shallower than 110 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

80 ft

median depth to water at rest · half between 50 and 129 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

9 gpm

median tested yield · half between 5 and 15 gpm

22% of tested wells produced under 5 gallons per minute and 15% 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 59316 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 Formation71 wells · 46% · median 180 ft
  • Fox Hills-hell Creek Aquifer51 wells · 33% · median 240 ft
  • Fox Hills Formation Or Sandstone15 wells · 10% · median 510 ft
  • Lance-hell Creek Undifferentiated8 wells · 5% · median 600 ft
  • Tullock Member (of Ft Union Fm.)7 wells · 5% · median 310 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. The most recent release reported here dates to 1992. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
