Well depth
How deep are wells in ZIP 59456?
Of 109 wells with a recorded total depth, the median is 26 feet. Half were drilled between 18 and 38 feet; one in ten went deeper than 56 feet and one in ten found water shallower than 15 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
13 ft
median depth to water at rest · half between 10 and 20 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
8 gpm
median tested yield · half between 2 and 11 gpm
35% of tested wells produced under 5 gallons per minute and 23% 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.

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 1995. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
