Florence: well depth, groundwater and water rights

What the public record says about water in Florence: 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 Florence?

Of 301 wells with a recorded total depth, the median is 64 feet. Half were drilled between 54 and 80 feet; one in ten went deeper than 100 feet and one in ten found water shallower than 40 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

34 ft

median depth to water at rest · half between 23 and 43 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

1% of tested wells produced under 5 gallons per minute and 65% 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.

Aquifers and geology

What wells in Florence 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.

  • Alluvial Fan Deposits - Pleistocene161 wells · 81% · median 59 ft
  • Sediments (tertiary)20 wells · 10% · median 99 ft
  • Alluvium (holocene)12 wells · 6% · median 59 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 2011. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
