Well depth

How deep are wells in ZIP 59647?

Of 225 wells with a recorded total depth, the median is 110 feet. Half were drilled between 75 and 200 feet; one in ten went deeper than 300 feet and one in ten found water shallower than 45 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

27 ft

median depth to water at rest · half between 14 and 51 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

15 gpm

median tested yield · half between 7 and 25 gpm

9% of tested wells produced under 5 gallons per minute and 40% 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 59647 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.

  • Sediments (tertiary)29 wells · 73% · median 80 ft
  • Alluvium (quaternary)9 wells · 23% · median 20 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 2021. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
