ZIP 59025: well depth, groundwater and water rights

Well depth

How deep are wells in ZIP 59025?

Of 969 wells with a recorded total depth, the median is 136 feet. Half were drilled between 50 and 249 feet; one in ten went deeper than 394 feet and one in ten found water shallower than 27 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.

Drilling activity

Recent well drilling in ZIP 59025

30 wells have been completed here since 2016, 3 of them in the last twelve months. The newest log on file was completed May 11, 2026. Records run back to 1899.

Water rights

Water rights on file in ZIP 59025

Montana DNRC lists 1,276 water rights with a point of diversion inside this area: 493 groundwater and 778 surface water, 985 of them active. The median priority date is 1949, and the oldest claim dates to 1868.

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 59025 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.

• Tongue River Member (of Ft Union Fm.)327 wells · 49% · median 170 ft
• Alluvium (quaternary)97 wells · 14% · median 33 ft
• Fort Union Formation60 wells · 9% · median 231 ft
• Anderson Coal Of The Ft Union Formation37 wells · 6% · median 159 ft
• Dietz Coal Of The Ft Union Formation24 wells · 4% · median 204 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.

Environmental groundwater screening

Documented environmental sites in ZIP 59025

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 2000. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
