Rader Creek: well depth, groundwater and water rights

What the public record says about water in Rader Creek: 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 Rader Creek?

Of 189 wells with a recorded total depth, the median is 230 feet. Half were drilled between 160 and 358 feet; one in ten went deeper than 440 feet and one in ten found water shallower than 80 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

70 ft

median depth to water at rest · half between 35 and 145 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

12 gpm

median tested yield · half between 8 and 20 gpm

8% of tested wells produced under 5 gallons per minute and 32% 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 Rader Creek 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.

  • Boulder Batholith5 wells · 83% · median 225 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.
