Well depth

How deep are wells in ZIP 59074?

Of 472 wells with a recorded total depth, the median is 80 feet. Half were drilled between 40 and 156 feet; one in ten went deeper than 299 feet and one in ten found water shallower than 21 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

30 ft

median depth to water at rest · half between 16 and 56 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

12 gpm

median tested yield · half between 5 and 25 gpm

21% of tested wells produced under 5 gallons per minute and 38% produced 20 or more. These are short completion tests, not sustained-capacity tests; a household typically needs 3 to 5 gpm with storage.

Aquifers and geology

What wells in ZIP 59074 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.

  • Eagle Sandstone74 wells · 28% · median 120 ft
  • Judith River Formation (of Montana Group)53 wells · 20% · median 80 ft
  • Colorado Shale Or Fm. (of Colorado Group)32 wells · 12% · median 90 ft
  • Alluvium (quaternary)21 wells · 8% · median 24 ft
  • Bearpaw Shale17 wells · 6% · median 120 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 2007. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
