Stonewall Gap, Colorado Well Guide

How deep are wells around Stonewall Gap?

How much water do wells make near Stonewall Gap?

Stonewall Gap well depths vary across the plains

The local median well depth is 60 feet. Half of the wells with reported depths fall between 45 and 140 feet, so a driller working on a typical Stonewall Gap parcel may be pricing a relatively shallow hole. The depth distribution is not uniform, however: 67% are under 100 feet, 20% are 100-300 feet, 8% are 300-600 feet, and 5% reach 600 feet or more.

The deepest recorded well is 1,110 feet. That outlier matters when comparing bids. Alluvium and plains sedimentary rock can produce very different drilling conditions from one parcel to the next, and permits identify 400 wells with unnamed or fractured-bedrock aquifers. Use the 60-foot median as a planning point, not a guarantee.

Most Stonewall Gap wells report useful production

Among the 77 wells reporting pump yield, the median is 12.0 gallons per minute. The middle half produces 7.0 to 14.0 gallons per minute, which is a solid range for many household uses when the well, pressure system, storage, and permitted use are properly designed.

Production is not uniformly strong. The records show 71% in the 5-15 gallon-per-minute range, 17% at 15 or more, 10% between 1 and 5, and 1% under 1 gallon per minute. A buyer should ask for the actual well construction report and pumping information, not rely only on the area median. A low-yield well may still work with storage, but it deserves a different budget and operating plan.

The recorded water level is shallow, but the trend is unclear

Only 22 wells in the Stonewall Gap data report a static water level, so the water-level sample is much smaller than the depth sample. Within that group, the median depth to water is 20 feet, and the middle half is 11-39 feet. Those figures suggest that water is often encountered relatively close to the surface in the reported wells.

The permit history does not provide a water-level series by decade, so it does not establish that the water table is rising or falling. Static water level can also differ by location, season, pumping history, and well construction. Have a driller check nearby logs and measure the well being considered before relying on a shallow-water assumption.

Permit activity runs from the 1950s through 2025

Stonewall Gap has a long permit history, with 408 wells in Colorado Division of Water Resources records and 245 recorded as constructed. Permit activity was highest in the 2010s, with 101 permits, followed by 98 in the 1990s and 60 in the 2000s. The newest permit in the supplied record is from 2025.

The most active named drillers are Boday Well Drilling, also recorded as Boday, Alex, with 47 wells; Snyder Well Pump Service, also recorded as Snyder, Marion M., with 37; and Authorized, recorded as Pe, Pg, with 32. These records show local experience, but they are not a recommendation or a guarantee of availability. Confirm licensing, scope, references, and what each bid includes.

A Stonewall Gap well may cost more than the hole itself

The local cost model uses a typical drilling rate of $35-$55 per foot for alluvium and plains sedimentary rock. At the 60-foot median depth, that puts the drilled hole at about $2,100-$3,300. This is only the drilling portion and should not be treated as the complete project price.

A finished well including the pump, pressure tank, trenching, and electrical is estimated at $8,100-$15,300 at the median depth. A deeper-than-typical hole, difficult access, casing or grout requirements, water treatment, or a low-yield design can change the bid. Ask every driller to separate drilling, casing, development, testing, pump equipment, trenching, and electrical work.

Check water quality, yield, septic, and building limits

Environmental screening deserves attention before buying. The mapped area within about 10 miles includes 354 PFAS sampling or contamination sites, 17 historic mine features, and 1 EPA Superfund or cleanup site. These mapped sites do not prove that a particular well is contaminated, but they are a reason to order a water test and investigate the parcel's history, drainage, and nearby land uses.

Low yield and dry-hole risk still need a site-specific review, especially because most permits name an unnamed or fractured-bedrock aquifer. Confirm the well permit and allowed use with Colorado DWR. Check septic setbacks, soil conditions, access for a rig, trench routes, building location, and the distance between the well and septic system. A parcel that can support a well may still need a different house or septic layout.

Well permits by decade near Stonewall Gap

What a new well costs in Stonewall Gap, 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 (140 ft) would run roughly $10,900–$19,700. See the full Colorado well cost guide.

Environmental sites mapped within about 10 miles

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 Stonewall Gap? 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 Stonewall Gap 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.
