How deep are wells around Blue Valley?

How much water do wells make near Blue Valley?

Blue Valley well depths reflect fractured mountain ground

Blue Valley wells have a median reported depth of 300 feet. The middle half runs from 180 to 460 feet, so a driller bidding a typical lot should not assume a shallow hole. Forty percent of wells fall between 300 and 600 feet, while 14% are 600 feet or deeper. The deepest recorded well is 3,523 feet.

That spread is consistent with mountain bedrock, where fractures control both drilling progress and water entry. The permit records identify an unnamed or fractured-bedrock aquifer for 2,517 wells, with smaller groups listed as Fractured Crystalline and Fractured Granite. Wells in Floyd Hill, Idaho Springs, Pine Valley, Upper Witter Gulch, and Echo Hills can provide useful comparison points, but the closest neighboring wells are more important than a broad area average.

Most Blue Valley wells produce usable household flow

Among the wells reporting a pump yield, the median is 7.0 gallons per minute. The middle half produces 4.0 to 10.0 gallons per minute, and 64% falls between 5 and 15 gallons per minute. Those results are generally workable for a home when the pressure system, storage, and plumbing are designed correctly.

Only 1% of reported wells are under 1 gallon per minute, but a low-yield result can still be a serious constraint on a specific lot. A yield test is not the same as unlimited supply. Ask for the well completion report, pump test information, storage-tank size, and any records of recovery after pumping. An exempt household-use well is generally limited to 35 gallons per minute under Colorado rules, and water use must still match the permit.

Water levels are deeper now than older measurements

The median static water level is 95 feet below the surface, with the middle half from 49 to 150 feet. That measurement describes where water stood when the well was checked, not the depth of the well and not necessarily the level during extended pumping.

The decade figures show a change worth investigating. The median measured level was 45 feet below surface in the 1970s, compared with 110 feet in both the 2010s and 2020s. That pattern is consistent with deeper measured water levels in the later records, although only 92 wells report a static water level and the measurements may come from different locations and conditions. A buyer should compare the actual neighboring wells rather than treating the series as a parcel-specific forecast.

Permit history runs from Idaho Springs to the newer records

Colorado DWR permit records contain 2,588 wells in this five-mile area. Of those, 1,670 are recorded as constructed, 1,629 report a total depth, and 881 report a pump yield. The permit history is concentrated in several periods: 588 permits were issued in the 1970s and 615 in the 1990s. The newest permit year is 2025.

The most frequently listed drillers are James Drilling Company, associated with Keaton and Michael K., with 302 records; Walton with 163; and Living Water Systems Inc., associated with Goble and Robert, with 155. These names describe historical permit records, not a recommendation or proof that a contractor is available for a new project. Confirm current licensing, insurance, references, and scope before hiring.

A 300-foot Blue Valley well starts around $19,500 to drill

In Blue Valley's fractured granite and gneiss, the modeled drilling rate is $65 to $100 per foot. At the 300-foot median depth, the drilled hole works out to about $19,500 to $30,000. A finished well, including the pump, tank, trenching, and electrical work, is modeled at about $25,500 to $42,000.

Those figures are planning ranges, not a guaranteed bid. Depth is the largest obvious variable, but access for the rig, casing and grout requirements, water testing, pump selection, trench length, and power work can change the total. Ask for a written allowance for additional footage and clarify what happens if the hole is dry or produces less than the target yield.

Mines, PFAS sites, and mountain construction need review

Mapped environmental information within about 10 miles includes 15 PFAS sampling or contamination sites, 2,838 historic mine features, and 15 EPA Superfund or cleanup sites. These mapped features do not prove that a particular well is contaminated, but they are a reason to review the parcel's location, historic land use, drainage, and available water-quality tests.

Low yield and dry holes remain possible in fractured bedrock even where nearby wells perform well. Test for bacteria and other constituents appropriate to the site, and ask a qualified professional to interpret the results. Septic setbacks, replacement-area requirements, steep access, trenching, and foundation work should be checked before closing. A good well does not by itself make a lot buildable.

Check the well, water rights, and building plan before buying

Start with the DWR permit and completion report for the property, then locate the nearest comparable wells. Compare depths, yields, static levels, pump equipment, and construction dates. For a home purchase, have the well flow and pressure tested and obtain current water-quality testing rather than relying on a neighbor's result.

Confirm that the permit authorizes the intended use. Domestic and household wells make up 88% of the records, while monitoring wells account for 8%; a permit's location in the database does not automatically establish the water rights or uses you need. If the lot is in an over-appropriated basin, an augmentation plan may be required. Before building, coordinate the well, septic system, driveway, electrical service, and emergency access as one site plan.

What a new well costs in Blue Valley, 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 (460 ft) would run roughly $35,900–$58,000. 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 Blue Valley? 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 Blue Valley 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.
