Well depth
How deep are wells in ZIP 59759?
Of 1,630 wells with a recorded total depth, the median is 115 feet. Half were drilled between 60 and 200 feet; one in ten went deeper than 303 feet and one in ten found water shallower than 37 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
42 ft
median depth to water at rest · half between 14 and 93 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
20 gpm
median tested yield · half between 15 and 30 gpm
4% of tested wells produced under 5 gallons per minute and 67% 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 59759 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)46 wells · 30% · median 116 ft
- Alluvium (quaternary)39 wells · 25% · median 56 ft
- Boulder Batholith22 wells · 14% · median 189 ft
- Sand And Gravel (holocene)16 wells · 10% · median 37 ft
- Sand And Gravel (tertiary)13 wells · 8% · 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 2024. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
