Sapphire Ridge: well depth, groundwater and water rights

What the public record says about water in Sapphire Ridge: 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 Sapphire Ridge?

Of 82 wells with a recorded total depth, the median is 100 feet. Half were drilled between 90 and 120 feet; one in ten went deeper than 130 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

50 ft

median depth to water at rest · half between 35 and 60 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

22 gpm

median tested yield · half between 17 and 35 gpm

0% of tested wells produced under 5 gallons per minute and 71% produced 20 or more. These are short completion tests, not sustained-capacity tests; a household typically needs 3 to 5 gpm with storage.

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 2023. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
