Stonegate, Colorado Well Depth, Yield, and Cost

How deep are wells around Stonegate?

How much water do wells make near Stonegate?

Stonegate wells commonly reach the Denver Basin

The median reported well depth near Stonegate is 338 feet. The middle half runs from 210 to 490 feet, so a driller bidding a typical site should be prepared for a substantial spread rather than treating the median as a guaranteed depth. Forty-five percent of reported wells are between 300 and 600 feet, while 13% reach 600 feet or more. Sixteen percent are under 100 feet and 26% fall from 100 to 300 feet.

The deepest record is 2,681 feet. That is an outlier, not a normal target, but it shows why a fixed-price assumption can be risky. Permits name unnamed or fractured-bedrock aquifers, Lower Dawson, and Denver. Denver Basin aquifer wells account for 100% of the records.

Yield is generally workable, but the well still matters

Among wells reporting pump yield, the median is 14.0 gallons per minute, with the middle half from 12.0 to 15.0 gallons per minute. Fifty-six percent report yields from 5 to 15 gallons per minute, and 44% report more than 15 gallons per minute. No recorded wells fall under 1 gallon per minute or between 1 and 5 gallons per minute in this dataset.

Those results are encouraging for a household buyer, but a nearby yield is not a guarantee for your parcel. Yield testing, pump sizing, storage, and the permitted use all matter. A household well is also subject to its permit terms; the general exempt-well pumping limit is 35 gallons per minute, not a promise that the aquifer will deliver that rate.

Water levels vary widely across Stonegate records

The median static water level is 170 feet below ground surface. The middle half spans 95 to 368 feet, a wide range that affects drilling, pump setting, electrical requirements, and the cost of getting water to the pressure tank. A bid should identify what water level it assumes and how the contractor handles a deeper-than-expected pump setting.

The decade series does not show a simple, continuous drop in the water table. Median depth to water was 114 feet in the 1970s, 230 feet in the 1980s, 662 feet in the 2000s, 315 feet in the 2010s, and 160 feet in the 2020s. Because only 199 records report static water level, treat the series as useful context rather than a parcel-specific trend.

Stonegate has a long permit and drilling history

Colorado DWR records contain 5,712 permitted wells in the Stonegate search area, with 2,924 recorded as constructed. The newest permit year is 2025. Permit activity was highest in the 1970s and 1980s, with 1,096 and 1,067 permits respectively, then declined to 833 in the 1990s, 599 in the 2000s, 439 in the 2010s, and 239 in the 2020s. Older records may be incomplete, so permit age alone does not establish current well condition.

Hier Drilling Co Inc, listed with Bruce A. Hier, appears on 850 records. Hier Drilling Co., listed with Peter J. Hier, appears on 602, and Authorized (Pe, Pg) appears on 401. These records show who has worked locally, not who is available or who will be the right fit for a new well.

A Stonegate well budget depends on depth and completion

The local drilling model uses a typical rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 338-foot median depth, the drilled hole works out to about $16,900 to $23,600. That is only the drilling portion. A finished well including pump, tank, trenching, and electrical is modeled at $22,900 to $35,600.

Use the middle-half depth range of 210 to 490 feet when comparing bids. A contractor who gives one narrow total without stating depth, casing, grout, pump, trenching, electrical, testing, and difficult-ground allowances is not giving you a useful comparison. Confirm what happens if the hole is dry, produces less than expected, or requires additional completion work.

Check water quality, septic space, and dry-hole risk

Mapped environmental information deserves attention before closing. Within about ten miles are 100 PFAS sampling or contamination sites, 8 historic mine features, and 7 EPA Superfund or cleanup sites. These mapped sites do not prove contamination at a particular parcel, but they are a reason to review site history, obtain a baseline water test, and understand groundwater flow before relying on an existing well.

Low yield and dry holes remain site risks even with strong area statistics. Verify the permit, construction report, casing and grout, pump test, static level, and recent laboratory results. Also confirm adequate separation and usable ground for septic, wells, driveways, and the planned building. An augmentation plan may be needed for new use in an over-appropriated basin.

What to do before buying or building in Stonegate

Start with the exact parcel, not just the neighborhood name. Pull nearby DWR permits and construction reports, then compare depth, yield, aquifer name, water level, and permitted use. Domestic or household use makes up 62% of the records, while stock accounts for 10%, irrigation 5%, and monitoring 10%; an existing permit may not authorize the use you want.

For a new build, have a licensed driller review access, geology, target depth, casing, grout, pump, storage, and power before you finalize a budget. Ask for a written dry-hole and low-yield policy. Test an existing well independently, inspect the pressure system, and make the purchase contingent on acceptable quantity, quality, and legal use.

What a new well costs in Stonegate, 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 (490 ft) would run roughly $30,500–$46,300. 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 Stonegate? 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 Stonegate 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.
