Colorado Well Finder › Wells by county › Rio Blanco County › Rangely
Buying land near Rangely means looking closely at the well record, not just assuming that every parcel has the same groundwater conditions. Within 5 miles of Rangely, Colorado DWR records include 119 permitted wells. Of those, 53 are recorded as constructed, 69 report a total depth, and only 2 report a pump yield.
The local record is unusual in one important way: the median reported well depth is 20 feet, while the deepest recorded well reaches 4,760 feet. Most wells are shallow, but that does not eliminate the need to verify the specific parcel, aquifer, intended use, and construction requirements.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Rangely. Not every permit reports every field; each statistic uses the wells that report it.

The median reported well depth near Rangely is 20 feet. The middle half of reported wells falls between 17 and 33 feet, and the 90th percentile is 47 feet. That gives a driller a reasonable starting point for a preliminary bid, especially in the local mixed sedimentary and alluvial ground.
Depth records still have a wide outlier range. Ninety-one percent of the reported wells are under 100 feet, while 3% are between 300 and 600 feet and 6% are deeper than 600 feet. No wells appear in the 100-to-300-foot range in this dataset. The deepest record is 4,760 feet, so a shallow median is not a guarantee for an individual lot.
The reported yield data looks strong, but it is based on only 2 wells with a pump yield in the records. Both reported yields fall in the 15-plus-gallons-per-minute category, producing a median of 15.0 gallons per minute. No recorded wells are listed under 1 gallon per minute, between 1 and 5, or between 5 and 15 gallons per minute.
That result should not be treated as a guarantee for a new domestic well. Most permits identify an unnamed or fractured-bedrock aquifer, with 112 wells in that category and 6 in an alluvial aquifer. Fractured ground can vary sharply over short distances. Ask for a pump test, well construction report, and actual recovery information before relying on the local yield figure.
Only 6 wells report a static water level, so the local water-table picture is limited. Among those records, the median depth to water is 4 feet, and the middle half ranges from 3 to 4 feet. That suggests shallow water in the wells that were measured, but it does not establish the water level beneath every parcel.
The permit-by-decade series shows activity rather than a water-table trend: 7 permits in the 1970s, 1 in the 1980s, 11 in the 1990s, 18 in the 2000s, 40 in the 2010s, and 15 in the 2020s. Because static levels are sparse and not presented as a consistent time series, these facts do not show that the water table is dropping or rising.
Permit activity is spread across several decades, with the largest recorded group in the 2010s. The newest permit year in this area is 2025. Monitoring is the dominant listed use at 58% of permits, while domestic or household wells account for 15%, stock for 8%, and irrigation for 2%. That mix matters when comparing a monitoring well with a proposed household well.
The most active driller name in the records is Authorized (Pe, Pg), associated with 37 wells. Pennell Drilling, listed with Pennell Jr., Clifford A., appears on 4 records, and Owner appears on 3. Confirm the driller, permit status, and construction report with Colorado DWR before using an old record as a model for your property.
For the local mixed sedimentary and alluvial ground, the drilling rate model is $50 to $75 per foot. At the 20-foot median depth, the drilled hole alone models to about $1,000 to $1,500. That is only the borehole, not the complete water system.
A finished well with pump, pressure tank, trenching, and electrical work is modeled at about $7,000 to $13,500 at the median depth. A deeper-than-typical hole, difficult access, casing and grout requirements, or additional treatment can move the final price higher. Get a written bid that separates drilling, casing, grout, pump equipment, trenching, electrical work, testing, and permit-related items.
The area has 41 mapped PFAS sampling or contamination sites within about 10 miles, 4 historic mine features, and 1 EPA Superfund or cleanup site. A nearby mapped site does not prove that a particular well is contaminated, but it is a reason to review available sampling, well location, groundwater flow information, and the history of the parcel.
Low yield and dry holes remain possible even where recorded yields look good, because only 2 permits report pump yield and much of the aquifer labeling is unnamed or fractured bedrock. Check septic setbacks, soil suitability, access for a drill rig, casing and grout requirements, and the legal water use allowed by the permit. Household-use wells are commonly exempt wells, but Colorado DWR permit conditions still control the use.
Before closing, pull the Colorado DWR records for the parcel and compare nearby wells by depth, aquifer description, construction, yield, and static water level. The records near Rangely include shallow wells, but the 4,760-foot outlier shows why a single median should not be used as a promise. Have a driller inspect access and ground conditions before you accept a fixed construction budget.
For a new home, coordinate the well, septic system, driveway, trenching, and electrical layout early. Confirm whether the proposed use is domestic, stock, irrigation, or another permitted use. If the property is near Dinosaur, Meeker, Maybell, Parachute, Battlement Mesa, or Loma, do not substitute those areas for a parcel-specific review; local geology and permit conditions can change quickly.

How this is built: the median permitted depth here times the per-foot range for this ground, plus the normal system costs. A lot at the 75th-percentile depth (33 ft) would run roughly $7,650–$14,475. See the full Colorado well cost guide.
Counts come from EPA, USGS and state datasets layered on the Colorado Well Finder map. A count is not a verdict on any one well; it tells you what to test for.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Rangely 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.

The median reported well depth within 5 miles of Rangely is 20 feet, with the middle half between 17 and 33 feet. Ninety-one percent of reported wells are under 100 feet. The record also includes a 4,760-foot well, so the local median is a starting point, not a guarantee for a particular property.
The local drilling model is $50 to $75 per foot. At the 20-foot median depth, the drilled hole is estimated at about $1,000 to $1,500. A finished system with pump, tank, trenching, and electrical work is modeled at about $7,000 to $13,500. Access and unusual depth can change the bid.
Only 2 wells in the records report a pump yield. Both are in the 15-plus-gallons-per-minute category, and the reported median is 15.0 gallons per minute. No recorded wells are listed below 15 gallons per minute. Because the sample is very small, request a pump test and recovery information for the property.
Safety depends on the individual well and its location. The mapped area includes 41 PFAS sampling or contamination sites, 4 historic mine features, and 1 EPA Superfund or cleanup site within about 10 miles. Those findings do not prove contamination at your parcel. Test the well for relevant contaminants and review local environmental records before drinking the water.
The available facts do not establish a rising or dropping water table. Only 6 wells report static water levels, with a median depth to water of 4 feet and a middle half from 3 to 4 feet. Permit counts vary by decade, but permit activity is not a substitute for a consistent long-term water-level record.
