Lone Tree, Colorado Well Depth, Yield, and Cost

How deep are wells around Lone Tree?

How much water do wells make near Lone Tree?

Lone Tree well depth depends on the ground below the lot

The median permitted well depth near Lone Tree is 307 feet. The middle half runs from 57 to 585 feet, so a bid based only on the median can miss the conditions at a particular property. About 33% of reported wells are under 100 feet, 15% fall from 100 to 300 feet, 29% from 300 to 600 feet, and 24% reach 600 feet or more. The deepest record is 3,220 feet.

These records name the unnamed or fractured-bedrock aquifer most often, along with Lower Dawson and Denver aquifers. All aquifer wells in the dataset are Denver Basin aquifer wells. In Denver Basin sedimentary bedrock, depth can change substantially over a short distance. Ask for nearby completed wells before treating a driller's depth allowance as a certainty.

Reported well yields around Lone Tree are generally usable

Among the wells reporting pump yield, the median is 13.0 gallons per minute, and the middle half is 10.3 to 15.0 gallons per minute. The reported mix is 58% between 5 and 15 gallons per minute, with 41% above 15 gallons per minute. No reported wells fall under 1 gallon per minute or between 1 and 5 gallons per minute in this dataset.

That is useful production for ordinary household planning, but it is not the same as unlimited water. Pump size, storage, pressure equipment, well recovery, and the permitted use all matter. An exempt household-use well is subject to Colorado rules, including the 35-gpm exempt-well pumping limit. Confirm the permit before assuming irrigation, livestock, or additional homes are allowed.

Water levels in Lone Tree do not show a simple steady decline

The reported static water level has a 395-foot median, with the middle half from 128 to 778 feet below the surface. Only 119 wells report a static water level, so this is a limited view rather than a complete groundwater trend for Lone Tree.

Measurements by decade vary considerably: the median was 284 feet in the 1970s, 1,150 feet in the 2000s, 415 feet in the 2010s, and 250 feet in the 2020s. The series does not move steadily downward; the 2000s are deepest, followed by shallower reported medians. Differences in location, aquifer, and measurement conditions may explain part of that spread. For a purchase, compare actual neighboring water levels and ask how the well performs during dry periods.

Permit history shows long activity and recent drilling

Lone Tree's surrounding permit record extends from the 1950s through the newest permit year, 2025. Permits issued by decade were 32 in the 1950s, 61 in the 1960s, 448 in the 1970s, 540 in the 1980s, 394 in the 1990s, 487 in the 2000s, 309 in the 2010s, and 214 in the 2020s. That history gives a buyer a substantial set of nearby records to investigate.

The most active drillers appearing in these records are Authorized (Pe, Pg), Hier Drilling Co Inc (Hier, Bruce A.), and Hier Drilling Co. (Hier, Peter J). A permit record is not a recommendation or a guarantee of current availability. It is a starting point for checking construction reports, depth, yield, aquifer, and the actual location of comparable wells.

What a new Lone Tree well may cost

The local drilling model uses a typical rate of $50 to $70 per foot for Denver Basin sedimentary bedrock. At the 307-foot median depth, the drilled hole models at about $15,400 to $21,500. That is only the hole. A finished well with pump, tank, trenching, and electrical models at about $21,400 to $33,500.

A buyer should use the middle-half depth range of 57 to 585 feet to understand the uncertainty in a bid. A shallow result and a deeper result will not carry the same drilling, casing, pump, trenching, or electrical cost. Request a written scope that identifies what happens if the hole is deeper than expected, the yield is inadequate, or the site needs more difficult access and installation work.

Check contamination, septic, and building constraints before closing

Mapped environmental information deserves a parcel-specific review. Within about ten miles of Lone Tree, the records include 120 PFAS sampling or contamination sites, 8 historic mine features, and 10 EPA Superfund or cleanup sites. A mapped site does not prove that a particular well is contaminated, but it is a reason to check the well location, water testing history, and groundwater direction with qualified professionals.

Low yield and dry-hole risk are not captured by the reported yield percentages alone, because only 713 wells report a pump yield and 1,602 report total depth. Septic setbacks, replacement-area needs, driveway access, grading, and the building envelope can limit a lot before drilling begins. Confirm DWR permitting, water-quality testing, septic design, and any augmentation requirement for the proposed use.

Use nearby records before buying or building in Lone Tree

Start with wells close to the parcel in Meridian, Acres Green, Meridian Village, Grand View Estates, Stepping Stone, and Sierra Ridge, then separate comparable wells by aquifer, use, depth, and construction date. The local median yield and depth are helpful for budgeting, but they do not replace a site-specific drilling opinion.

For a purchase, make the well permit, construction report, pump information, water test, and legal water use part of due diligence. For a new build, have the driller and septic designer review access, setbacks, storage, electrical service, and the proposed house location together. In an over-appropriated basin, an augmentation plan may be required for the intended use. Colorado DWR can confirm the permit rules before you commit.

Well permits by decade near Lone Tree

What a new well costs in Lone Tree, 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 (585 ft) would run roughly $35,250–$52,950. 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 Lone Tree? 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 Lone Tree 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.
