St. Pierre: well depth, groundwater and water rights
What the public record says about water in St. Pierre: 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 St. Pierre?
Of 65 wells with a recorded total depth, the median is 104 feet. Half were drilled between 67 and 135 feet; one in ten went deeper than 160 feet and one in ten found water shallower than 33 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
23 ft
median depth to water at rest · half between 12 and 39 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
10 gpm
median tested yield · half between 8 and 20 gpm
14% of tested wells produced under 5 gallons per minute and 26% 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. A property report screens the sites within a quarter, half and one mile of a specific parcel and links the agency records.
