Water in Mineral County
What the state and federal record says about water across Mineral County. Each figure names the agency it came from.
Can I drill a well here?
It depends on your lot: its size, and when it was created
-
Where the lot decides (over-appropriated ground)
What a household well may serve depends on the lot's size and on when and how it was created:
Lot of 35 acres or more
A household well can serve up to three homes, one acre of lawn and garden, and livestock. A 35-acre tract platted as part of a subdivision counts as part of the subdivision instead.
Under 35 acres, created before June 1, 1972 or by a county exemption
A household well for use inside one house only. No lawn, garden or livestock.
Under 35 acres, in a subdivision approved June 1, 1972 or later
No well by right. DWR weighs every well in the subdivision together, so in practice the subdivision's own water supply plan decides what a well may do.
-
Household well, any lot size
A household well can serve up to three homes, one acre of lawn and garden, and livestock, whatever the size of the lot.
-
On a rule boundary
A basin or over-appropriation line crosses these sections, so the answer turns on where on the lot the well would sit.
- This is the San Luis Valley (Water Division 3). The state declares the whole Rio Grande basin over-appropriated, so the lot decides what a household well may serve. Any well bigger than a household well must pump under a subdistrict plan, an augmentation plan or a substitute water supply plan.
- One exempt well per legal parcel. Inside a town or a water district's service area DWR generally issues no household well permit.

894 surveyed sections, drawn one square mile to a square. The shading is scaled against every county in Colorado, so a color means the same thing on any of these pages. The outline is the county boundary from the Census Bureau: ground inside the line and outside the shading is ground nobody has drilled, filed on or addressed. Aerial imagery is the USGS National Map.
It takes a long time to get from permit to water here
The median well takes 85 days from permit issue to completion, against 21 days in the median county. Worth knowing before you plan a build around drilling next spring.

A lot of the water here is decreed to stay in the stream
16% of rights are instream flow rights, against 2% in the median county, held by the Water Conservation Board to keep water in the channel rather than take it out. They are senior water that will never be diverted, and on a short stream they set the floor everyone junior to them lives under.

Almost nowhere in this county is on a piped water system
The federal register lists 3 active community water systems for the whole county, against 10 in the median county. Unless a property sits inside one of them it is on a well, a cistern, or a shared private supply.

A lot of this county is wet ground
68% of sections carry poorly drained soil, meaning a water table close to the surface for part of the year. A foundation and septic constraint, and often the most productive ground on a property.

Water systems here have unresolved health violations
3 of this county's 3 community water systems carry a health-based violation that has not been returned to compliance. Health-based means contamination or a treatment failure, not late paperwork.

Every town here drinks the same water a well would draw
All 3 of this county's community water systems run on groundwater rather than surface water. A municipal supply is the best-monitored well in the county, so its record is the closest thing to a free test of the aquifer under this ground.

A lot of the water decreed here was never built
8% of rights are conditional only. A court said somebody may build it and nobody has.
