Circle: well depth, groundwater and water rights
What the public record says about water in Circle: 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 Circle?
Of 70 wells with a recorded total depth, the median is 35 feet. Half were drilled between 28 and 37 feet; one in ten went deeper than 165 feet and one in ten found water shallower than 28 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
27 ft
median depth to water at rest · half between 25 and 27 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
43 gpm
median tested yield · half between 10 and 50 gpm
0% of tested wells produced under 5 gallons per minute and 60% 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 2020. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
