Guffey, Colorado Well Depth, Yield, and Cost

How deep are wells around Guffey?

How much water do wells make near Guffey?

Guffey well depth reflects fractured mountain rock

A Guffey driller bidding a new well will usually be working in fractured granite or gneiss. The local median depth is 248 feet. Half of the wells with reported depths fall between 150 and 340 feet, while the 90th-percentile depth is 450 feet. The deepest recorded well reaches 1,000 feet.

The depth mix shows why a single shallow estimate is risky: 53% are between 100 and 300 feet, 38% are between 300 and 600 feet, and 7% are under 100 feet. Only 2% reach 600 feet or more. For a buyer, neighboring permits can help set a drilling range, but fractured rock can change quickly across a mountain property. Ask for a bid that explains what happens if the hole must continue past the planned depth.

What Guffey wells usually produce

Of the permitted wells with a reported pump yield, the median is 8.0 gallons per minute. The middle half produces 5.0 to 10.0 gallons per minute, so that range is a reasonable starting point for discussing household supply, storage, and pump selection with a contractor.

Low-yield wells are present, but they are not the dominant result: 4% report under 1 gallon per minute, 20% report 1 to 5 gallons per minute, 68% report 5 to 15 gallons per minute, and 8% report more than 15 gallons per minute. A well producing under 1 gallon per minute may still work with adequate storage, but it gives a buyer less margin for peak household use. Confirm the testing method and consider storage rather than judging the property from a permit number alone.

Guffey water levels and the measured trend

Only 52 wells in the records report a static water level, so the water-level sample is much smaller than the depth or permit sample. In those records, the median depth to water is 95 feet, with the middle half between 65 and 138 feet below the surface.

The decade comparison moves from a median of 92 feet below surface in the 2010s to 102 feet in the 2020s. That is a deeper measured water level in the later decade, but the available measurements are limited and may not represent the same wells, seasons, or conditions. It is not enough by itself to establish a broad water-table decline. For a lot under contract, ask for the closest static-water measurements and have a driller evaluate casing, grout, pump setting, and expected drawdown.

Who has drilled around Guffey, and when

Permit activity is spread across several decades. The records show 5 permits in the 1960s, 67 in the 1970s, 93 in the 1980s, 231 in the 1990s, 103 in the 2000s, 72 in the 2010s, and 57 in the 2020s. The newest permit year is 2025, so this is not only an old-well area.

Mountain Well Improvement LLC, listed with Wiley, David D., appears most often with 178 records. Woods Drilling Inc., listed with Woods, William D., has 49, and Black Mountain Drilling, listed with Schnoes, Adam J., also has 49. Those records describe local permit history, not a guarantee of current availability, price, or workmanship. Check current licensing, references, and a written scope before selecting a driller.

What a new Guffey well may cost

The local cost model assumes fractured mountain bedrock and a drilling rate of $65 to $100 per foot. At the 248-foot median depth, the drilled hole works out to about $16,100 to $24,800. That is the hole only, not the complete water system.

A finished well with pump, pressure tank, trenching, and electrical is modeled at $22,100 to $36,800 at that median depth. A property requiring 450 feet or more could cost substantially more than the median-depth example, while a shallower hole may cost less. Get the driller to separate footage, casing, grout, pump equipment, water testing, trenching, electrical, and any difficult access charges. A permit record can help with expectations, but it does not lock in a bid.

Guffey risks to investigate before buying

Low yield and dry-hole risk deserve attention because most permits identify unnamed fractured-bedrock aquifers, with 663 wells in that category and 9 identified as Fractured Granite. The records include 4% of reported yields under 1 gallon per minute, so ask how a failed or marginal hole is handled financially before work begins.

Environmental review also matters. Within about 10 miles, the map includes 3 PFAS sampling or contamination sites and 205 historic mine features, although there are 0 EPA Superfund or cleanup sites. That does not prove a problem on a particular parcel. Test an existing well before closing and consider a broader water-quality review where mine workings or PFAS sites are relevant. Confirm septic setbacks, usable building area, access for drilling equipment, and the location of the well relative to the septic system.

A practical plan for a Guffey lot

Start with the nearest permitted wells, not just the countywide story. Compare their depths, reported yields, static water levels, completion information, and use. The local permit mix is 94% domestic or household and 21% stock, with no irrigation or monitoring wells reported, so a buyer should verify that the existing permit supports the intended use.

For new construction, have a driller walk the site before finalizing the house location. Plan the well, septic system, driveway, electrical route, and storage together. Colorado DWR permitting and exempt household-use rules apply, and an exempt well has a 35-gallon-per-minute pumping limit. In an over-appropriated basin, an augmentation plan may be required. Make the purchase contract address water testing, well inspection, production testing, and the consequences of an unsuccessful hole.

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 Guffey? 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 Guffey 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.
