Colona, Colorado Well Depth, Yield, and Cost

How deep are Colona wells?

The median reported well depth near Colona is 244 feet. The middle half runs from 92 to 361 feet, which is a substantial spread for estimating a drilling bid. The 90th percentile reaches 596 feet, and the deepest recorded well is 840 feet.

Depth is distributed across the area: 27% of wells are under 100 feet, 32% fall from 100 to 300 feet, 31% from 300 to 600 feet, and 10% exceed 600 feet. For a buyer, the median is a starting point, not a ceiling. Mixed sedimentary and alluvial ground can change the drilling approach and final depth from one parcel to the next.

What Colona wells produce

Among the 53 wells that report pump yield, the median is 10.0 gallons per minute, with the middle half from 4.0 to 12.0 gallons per minute. The records show 6% under 1 gallon per minute, 21% from 1 to 5, 55% from 5 to 15, and 19% above 15.

That distribution is generally workable for a household, but a reported yield is not the same as storage, pressure, or dependable long-term supply. Ask for the actual well construction and pump information. A low-producing well may still serve a home with suitable tank storage, while irrigation or stock use can require a different water-rights review.

Water levels around Colona

The 15 reported static water levels have a median depth to water of 144 feet. The middle half ranges from 67 to 179 feet below ground. Those figures help a contractor think about pump setting, trenching, and electrical work, but they are not a complete groundwater trend.

There are too few reported static levels to conclude from these records alone that the water table is dropping or stable. Water levels can vary with season, nearby pumping, and the aquifer intercepted by the well. Have the driller check current conditions and compare the closest completed wells rather than relying only on the area median.

Colona permit history and drillers

Permits were issued throughout the area’s recorded history, with 8 in the 1950s, 4 in the 1960s, 36 in the 1970s, 34 in the 1980s, 46 in the 1990s, 52 in the 2000s, 21 in the 2010s, and 24 in the 2020s. The newest permit year is 2025. Domestic or household use accounts for 69% of permits, while stock use accounts for 25%.

Valley Drilling Co. (Stoy, Kenneth) appears most often, with 60 records. Western Drilling Services, Llc (Kuchler, Richard A.) has 15, and Groundwater Dev. Inc. (Kuchler, Michael S.) has 14. These records show local experience, not a guarantee of availability or price.

What a new Colona well can cost

The local cost model uses a drilling rate of $50 to $75 per foot for mixed sedimentary and alluvial ground. At the 244-foot median depth, the drilled hole works out to about $12,200 to $18,300.

A finished system with pump, tank, trenching, and electrical is modeled at about $18,200 to $30,300. A deeper-than-median hole, difficult access, casing or grout requirements, or changes to the site plan can move the bid higher. Get the drilling scope in writing and ask what happens if the hole is dry or produces less than expected.

Before construction, confirm the permit requirements with Colorado DWR. An exempt household-use well still has defined limits, including the 35 gpm exempt-well pumping limit, and an over-appropriated basin may require an augmentation plan.

Risks to check before building near Colona

Low yield and dry-hole risk deserve attention because depth and production vary widely. The aquifer names on permits are mostly unnamed or fractured-bedrock aquifers, with 287 wells in that category. Fractured rock can be unpredictable: a nearby successful well does not prove the same result on your lot.

Environmental screening also matters. Within about 10 miles, the records show 1 PFAS sampling or contamination site and 6 historic mine features, with 0 EPA Superfund or cleanup sites. That does not establish contamination at a parcel. Test the water after construction and check local site history.

Keep the well, septic system, replacement area, access, and house location coordinated. Confirm setbacks, drainage, casing and grout details, and year-round access for a drill rig and service truck before buying or grading.

Buying land around Colona

Start with the closest completed wells, not just the regional median. The area includes Loghill Village, Montrose, Ridgway, Portland, Ouray, and Olathe, but conditions can change quickly across those broader surroundings. Within the Colona search area, compare depth, reported yield, static water level, use, and aquifer description for parcels that resemble the one you are considering.

For a new homesite, make the well permit, septic feasibility, driveway access, and house location part of the same review. Budget around the local cost model while allowing for a deeper hole or difficult site. A Colorado driller can also explain casing, grout, pump sizing, and what testing is appropriate after completion.

What a new well costs in Colona, CO

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 (361 ft) would run roughly $24,050–$39,075. 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.

Buying land near Colona? 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 Colona 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.

• Instant Online Report, $99 — type the address and get a buildability read on the spot: parcel, terrain and slope, soil and septic outlook. Cheap enough to run on every lot you're shopping.
• Desktop Report, $500 — a contractor's from-the-desk feasibility read: Regulation 43 and county code, GIS parcel data, terrain, flood and drainage, soil and septic viability, setbacks and buildable envelope, nearby well depths from our 591,000-well database, the likely driveway route, and a preliminary site-development cost breakdown.
• On-Site Report, $2,000 — everything above, then boots and a drone on the actual ground: house pad and septic zone located, access and winter conditions checked, rock and soil observed in person, a 15 to 20 page written opinion you can hand a lender or seller. Credited toward your project if you build with us.

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.
