Colorado Well Finder › Wells by county › Boulder County › Lazy Acres
Buying land in Lazy Acres means dealing with mountain bedrock, variable well depths, and water supplies that can change from one lot to the next. Permitted wells within five miles show a 230-foot median depth and a 7.0-gpm median reported yield, but those figures are only a starting point for a specific property.
Most permits identify fractured bedrock rather than a named basin aquifer. That makes nearby well records especially useful. Sunshine, Altona, Crisman, Pine Brook Hill, Seven Hills, and Jamestown can provide local comparison points, but a neighboring result is not a guarantee for a new hole.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Lazy Acres. Not every permit reports every field; each statistic uses the wells that report it.

The median reported well depth around Lazy Acres is 230 feet. The middle half runs from 65 to 400 feet, meaning a driller bidding a normal residential well should allow for a broad range rather than treating 230 feet as a fixed target. The 90th-percentile depth is 600 feet, and the deepest record reaches 4,550 feet.
The depth mix tells the same story: 30% of wells are under 100 feet, 29% are 100 to 300 feet, 30% are 300 to 600 feet, and 11% exceed 600 feet. Most permits name an unnamed fractured-bedrock aquifer. Granite and gneiss fractures control where water is found, so two nearby lots can require very different drilling plans.
Among wells with a reported pump yield, the median is 7.0 gallons per minute. The middle half is 5.0 to 10.0 gpm, and 69% report between 5 and 15 gpm. Another 11% report more than 15 gpm, while 17% fall between 1 and 5 gpm and 2% are under 1 gpm.
For a buyer, a 7.0-gpm result is a useful working reference, not a promise. A 2% share under 1 gpm shows that very low-producing wells do occur. Ask for the well construction report, pump test information, storage capacity, and any permit conditions. Household-use exempt wells remain subject to their allowed uses and the applicable pumping limit.
Reported static water levels have a 41-foot median depth to water, with the middle half from 10 to 100 feet below the surface. That range matters for pump setting, electrical planning, and estimating how much standing water may be available in the casing.
The decade series does not show a simple steady decline. Median depth to water was 34 feet in the 1960s, 36 feet in the 1970s, 72 feet in the 1980s, 80 feet in the 2010s, and 58 feet in the 2020s. Only 127 records report a static water level, so treat the series as local historical context rather than proof of a basin-wide trend. Seasonal conditions, elevation, fracture connections, and measurement timing can all affect a result.
The records include 4,085 permitted wells within five miles, with 2,735 recorded as constructed. Of those records, 2,869 report a total depth, 918 report a pump yield, and 127 report a static water level. The newest permit year is 2025, so this is not only an old mining or homestead dataset.
Permit activity was highest in the 1970s, with 874 permits. The records identify Ground Water Systems Inc (Wilson, Richard R.) most often, with 816 wells, followed by Ingram Drilling Inc. (Ingram, Stephen E.) with 205 and Walton, with 195. Confirm current licensing, insurance, scheduling, and the exact scope of a bid before selecting a driller.
Lazy Acres drilling is priced for fractured mountain bedrock, including granite and gneiss. The typical drilling rate is $65 to $100 per foot. At the 230-foot median depth, the drilled hole models to about $15,000 to $23,000.
A finished residential well, including the pump, pressure tank, trenching, and electrical work, models to about $21,000 to $35,000 at that median depth. A bid can move outside that range when the hole must go deeper, access is difficult, casing or grout requirements change, or the water system needs additional treatment or storage. Have the contractor state what is included and what happens if the well is low-producing or unsuccessful.
Yield is not the only risk. The mapped area within about ten miles includes 91 PFAS sampling or contamination sites, 596 historic mine features, and 65 EPA Superfund or cleanup sites. Those mapped locations do not establish contamination on a particular parcel, but they are a reason to test an existing well and review nearby land uses, mine history, and water-quality records before closing.
Ask about dry-hole terms, low-yield remedies, casing and grout, pump setting, and the required water-quality panel. A septic system also needs suitable soil, setbacks, a reserve area, and room for construction equipment. Confirm the building envelope, driveway access, electrical route, and well-septic separation with the county and qualified contractors. In an over-appropriated basin, an augmentation plan may be relevant; verify the permit's allowed use before relying on the water.
Start with the parcel's own permit and construction records, then compare wells in Sunshine, Altona, Crisman, Pine Brook Hill, Seven Hills, and Jamestown. Look for depth, reported yield, static level, completion details, and the age of the pump. The broader record is useful for estimating risk, but fractured rock does not distribute water evenly.
For an existing home, obtain a current production check and water test rather than relying on a seller's description. For vacant land, make the well contingency specific: access for a rig, target depth, testing method, acceptable yield, and responsibility for a dry or low-yield hole. Price the full water system and septic work together. DWR permit review, site access, and a local driller's opinion should all be part of the purchase decision.

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 (400 ft) would run roughly $32,000–$52,000. See the full Colorado well cost guide.
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.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Lazy Acres 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.
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.

The median permitted well depth near Lazy Acres is 230 feet. The middle half runs from 65 to 400 feet, while the 90th-percentile depth is 600 feet. Records range as deep as 4,550 feet. Because most permits name fractured bedrock, a nearby well is useful evidence but cannot predict the exact depth on a different lot.
The modeled drilling rate in Lazy Acres is $65 to $100 per foot. At the 230-foot median depth, the drilled hole is about $15,000 to $23,000. A finished system with pump, tank, trenching, and electrical work is about $21,000 to $35,000. Bedrock conditions, access, depth, and low-yield provisions can change the bid.
The median reported yield near Lazy Acres is 7.0 gallons per minute, with the middle half from 5.0 to 10.0 gpm. Most reported wells, 69%, produce between 5 and 15 gpm. However, 2% report under 1 gpm, so buyers should review the actual well test and storage setup instead of relying only on the area median.
The available well records do not prove that any individual well is safe to drink. About ten miles around Lazy Acres contain 91 PFAS sampling or contamination sites, 596 historic mine features, and 65 EPA Superfund or cleanup sites. Test the property's water through a qualified laboratory, review nearby land uses, and retest when conditions or ownership change.
No permitted wells in the supplied records are identified as Denver Basin aquifer wells. Most, 3,853, are assigned to an unnamed or fractured-bedrock aquifer. Only 21 are listed as Alluvial and 10 as Quaternary Alluvium. Review the actual permit for allowed uses, because an exempt household-use well is not automatically a source for unrestricted irrigation or other uses.
