Dolores County Well Records

What to Expect From a Well in Dolores County

Colorado Well FinderWells by county › Dolores County

A Dolores County well budget starts with the ground under the lot, not the county average. Recorded wells have a median depth of 150 ft and a median reported yield of 7.0 gpm, but neither figure guarantees what a new borehole will produce.

Colorado DWR records include 597 permitted wells countywide, with 394 recorded as constructed. Use these records to narrow your search around Dove Creek or Rico, then compare nearby completed wells with similar terrain and geology before committing to land or a drilling contract.

A 150 ft Baseline, With Room for Deeper Drilling

Among the 411 wells reporting depth, the median is 150 ft and the middle half run 82-245 ft. That spread matters more to a drilling bid than the median alone: ask for a scope that explains what happens if drilling passes the expected depth without finding adequate water.

Most recorded depths fall in the 100-300 ft range, accounting for 62%. The deepest recorded well is 1220 ft, an outlier rather than a sensible starting budget. Permits mostly identify an unnamed or fractured-bedrock aquifer. In fractured rock, water depends on the openings a borehole intersects, so a productive neighboring well is useful evidence, not a promise.

Reported Yield Is Usually Useful, but Low Producers Matter

Only 96 wells report a pump yield. Their median is 7.0 gpm, with a middle half of 3.2-11.0 gpm. That suggests workable household supplies are common among the reporting wells, but a reported drilling yield is not proof of sustained performance under daily use.

The 5% reporting less than 1 gpm deserve a buyer's attention. A low-producing well may need storage and careful demand management, and some supplies may not support the intended use. Another 27% report 1-5 gpm. Before buying, have the well's production and recovery evaluated, and confirm the permit allows your planned household, livestock or outdoor uses. Physical capacity and legal permission are separate questions.

Water at 60 ft Does Not Mean a 60 ft Well

The median static water level is 60 ft below ground, with the middle half at 30-103 ft. These measurements describe resting water levels, not total borehole depth or the level reached while pumping. A driller may need to go substantially below the resting level to intercept productive fractures and provide a workable well completion.

Only 35 wells report static water levels, so this is a limited countywide snapshot. It does not establish a falling or rising water table. For a property near Rico or Dove Creek, prioritize measurements from that well over time and a current pumping evaluation rather than treating the county median as a local groundwater forecast.

Dolores County's Permit History and Recorded Drillers

Permit issuance rose from 50 in the 1980s to 107 in the 1990s and 146 in the 2000s. Records show 73 in the 2010s and 49 in the 2020s, with the newest permit dated 2025. The latest decade is incomplete; its count should not be read as a finished comparison.

Mcpherson Drilling Co. appears on 138 records, Ucolo Drilling Llc on 59, and Kilby'S Water Well Service on 19. Those are historical record counts, not confirmation of current availability. Domestic/household uses account for 72% of the use mix and stock uses for 18%. Check the actual permit conditions rather than assuming a neighboring household well authorizes the same uses you need.

Budget Beyond the Drilled Hole in Dolores County

The supplied cost model assumes fractured mountain bedrock, described as granite or gneiss, at $65-$100 per foot. At the 150 ft median depth, that puts the drilled hole at about $9,800-$15,000. A finished well with pump, tank, trenching and electrical is estimated at $15,800-$27,000.

Treat those figures as planning allowances, not a parcel quote or confirmation of the rock beneath every lot. The 82-245 ft middle depth range leaves meaningful room for cost variation. Ask bidders to identify casing and grout, difficult-ground charges, pump selection, access requirements and the utility route. Get clear terms for deeper drilling or an unsuccessful borehole before equipment arrives.

Mine Features, Water Quality and Site Layout

Mapped environmental records within about 10 miles include 4 PFAS sampling/contamination sites, 8 historic mine features and 1 EPA Superfund/cleanup site. These are screening flags, not evidence that a particular well is contaminated. Review each site's status and location relative to the property, then choose laboratory testing with local health or water-quality guidance.

Yield records also cannot establish the likelihood of a dry hole: permitted wells and reported pump tests are not a complete log of unsuccessful drilling. Check casing, grout and surface drainage on an existing well. For new construction, coordinate the well location with septic siting, the building footprint and drill-rig access before finalizing the layout.

Before Closing on a Rico or Dove Creek Lot

Start with the parcel's DWR permit and completion records, then compare nearby wells in similar terrain. Rico and Dove Creek share countywide statistics, not necessarily drilling conditions. Records across the line in Montezuma County or San Miguel County may help provide context, but nearby geology matters more than a county boundary.

For an existing home, make satisfactory water-quality and production evaluations part of your purchase due diligence. For vacant land, confirm the available permit pathway and allowed uses with DWR before assuming household, stock or irrigation water is available. Have drilling access, septic feasibility and the house location reviewed together, and retain budget flexibility until the well is completed and tested.

Buying land near Dolores County? Know what it costs to build before you buy the dirt.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Dolores County can carry the same asking price while one needs an $80,000 driveway and a $45,000 engineered septic the other doesn't. The well numbers on this page are the start of that answer. A Tri-Lakes Site Feasibility Report is the rest of it: a licensed general contractor, excavator and septic installer reads the parcel the way we would if we were about to build on it, and puts the real cost in writing before your money is committed.

Spend a little to know. Or gamble a lot to guess. Realtors sell the view and inspectors look at houses that already exist. We're the people who'd build it, so we catch what quietly turns a "great deal" into a budget disaster: bad access, buried rock, steep grade, soil that won't pass for a normal septic, water that's a fortune to reach. And if the lot is good, you've already got a builder ready to do the work, driveway to drywall.

Under contract, comparing parcels, or a realtor with a rural listing whose buyers keep asking "what will it cost to build here?" This is the due-diligence step almost everyone skips, and the one that saves the most.

Common questions about wells in Dolores County

How deep are wells in Dolores County, Colorado?

The median recorded depth is 150 ft among 411 wells reporting depth. The middle half are 82-245 ft, and 62% fall in the 100-300 ft range. Fractured-bedrock conditions make individual results variable, so use nearby completion records and a parcel-specific drilling assessment rather than budgeting solely from the county median.

How much does it cost to drill a well in Dolores County?

The planning model uses $65-$100 per foot for fractured mountain bedrock. At the 150 ft median depth, the drilled hole is about $9,800-$15,000, while a finished well with pump, tank, trenching and electrical is about $15,800-$27,000. Confirm casing, grout, access and deeper-drilling charges in the written bid.

How much water do wells produce in Dolores County?

Among 96 wells reporting pump yield, the median is 7.0 gpm and the middle half produce 3.2-11.0 gpm. The records include 5% below 1 gpm. Have an existing well's sustained production and recovery evaluated before purchase; a historical yield entry does not guarantee current performance or authorize every intended use.

Is well water safe to drink in Dolores County?

Safety requires testing the individual well. Mapped records within about 10 miles include 4 PFAS sampling/contamination sites, 8 historic mine features and 1 EPA Superfund/cleanup site, but those counts do not establish contamination in your water. Review nearby environmental records and arrange laboratory testing suited to the property and potential sources.

How far down is the water table in Dolores County?

Reported static water levels have a median depth of 60 ft below ground, with a middle half of 30-103 ft. Only 35 wells provide these measurements. They describe resting levels, not pumping levels or required drilling depth, and do not establish a countywide trend. Current measurements at the property are more useful for a purchase.
