ZIP 59063: well depth, groundwater and water rights

What the public record says about water in ZIP code 59063: how deep wells go, where the water table sits, what wells produce, which water rights are on file, and which documented environmental sites are nearby. Area statistics orient you; a property report analyzes the records around one specific parcel.

Well depth

How deep are wells in ZIP 59063?

Of 959 wells with a recorded total depth, the median is 32 feet. Half were drilled between 26 and 40 feet; one in ten went deeper than 81 feet and one in ten found water shallower than 23 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

12 ft

median depth to water at rest · half between 9 and 18 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

40 gpm

median tested yield · half between 25 and 60 gpm

4% of tested wells produced under 5 gallons per minute and 86% 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 59063 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.

  • Alluvium (quaternary)531 wells · 71% · median 31 ft
  • Sand And Gravel (quaternary)47 wells · 6% · median 38 ft
  • Judith River Formation (of Montana Group)32 wells · 4% · median 128 ft
  • Eagle Sandstone31 wells · 4% · median 118 ft
  • Sand And Gravel (pleistocene)20 wells · 3% · median 39 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 2016. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
