Holly Colorado Well Depth, Yield, and Drilling Costs

How deep are wells around Holly?

How much water do wells make near Holly?

Holly well depths reflect shallow plains geology

The median reported well depth near Holly is 94 feet. The middle half runs from 56 to 148 feet, which is the most useful range for an initial drilling estimate. Depths still vary widely: 53% of reported wells are under 100 feet, 34% fall between 100 and 300 feet, 12% are between 300 and 600 feet, and 1% exceed 600 feet.

The deepest well in the record is 815 feet. Local ground conditions are described as alluvium and plains sedimentary rock, but a particular lot can encounter different saturated zones, coarse material, or tighter rock. A driller should review nearby completion records rather than bid from the median alone. The 90th-percentile depth is 375 feet, so a contingency for a deeper hole matters when comparing bids.

Reported Holly yields are high, but the sample is limited

Among the 80 wells that report a pump yield, the median is 800.0 gallons per minute. The middle half ranges from 15.0 to 1462.5 gallons per minute, and 88% report at least 15 gallons per minute. The records show 12% in the 5-to-15-gallon-per-minute range, with 0% under 1 gallon per minute and 0% between 1 and 5 gallons per minute.

Those figures are not a guarantee for a new household well. The yield records are dominated by the local use mix, including 45% irrigation wells, compared with 14% domestic or household and 14% stock wells. Ask what test produced the reported yield, how long it ran, and whether the result applies to a domestic pump and storage system.

Holly water levels need parcel-specific checking

Only 10 permitted wells near Holly report a static water level, so the water-level dataset is too small to establish a dependable local trend. The reported median depth to static water is 145 feet, with the middle half from 74 to 212 feet.

That range is important when planning casing, pump placement, trenching, and electrical work. A shallow well depth does not automatically mean shallow water at every location, and a deeper water level can affect pump selection even when the drilled hole is not unusually deep. Ask for the well construction report and static water-level information for the actual property and nearby wells. The permit record includes 512 wells assigned to an unnamed or fractured-bedrock aquifer, 11 in the Ogallala, and 6 in the Dakota Sandstone.

Holly permit history shows long-running well activity

Holly has a long permit history rather than a burst of only recent construction. The records show 7 permits from the 1950s, 28 from the 1960s, 60 from the 1970s, 23 from the 1980s, 50 from the 1990s, 76 from the 2000s, 71 from the 2010s, and 2 from the 2020s. The newest permit year in this dataset is 2021.

The most frequently listed drillers are Ark Valley Pump & Supply (Smith Jr., William), with 56 records; Authorized (Pe, Pg), with 49; and Ark Valley Pump & Supply (Smith, William David), with 43. Those names describe permit history, not a recommendation or proof that a company is currently available. Verify licensing, insurance, references, and the proposed completion before hiring.

A median-depth Holly well pencils out at a specific range

For Holly's alluvium and plains sedimentary rock, the drilling model uses $35-$55 per foot. At the 94-foot median depth, the drilled hole comes to about $3,300-$5,200. That is only the hole. A finished well including pump, tank, trenching, and electrical is estimated at about $9,300-$17,200.

A bid based on 94 feet may be reasonable for a typical shallow well, but it should not be treated as a fixed price. The record includes wells as deep as 815 feet, and the middle-half range extends to 148 feet. Request separate pricing for drilling, casing and grout, pump equipment, electrical service, trenching, water testing, and any extra footage. Confirm what happens if the hole is dry or the yield is inadequate.

Check water quality, low-yield risk, and the homesite

Mapped environmental information within about 10 miles includes 4 PFAS sampling or contamination sites and 1 historic mine feature. There are 0 EPA Superfund or cleanup sites in that mapped set. That does not establish the quality of a particular well. Test existing water before buying when possible, and plan baseline testing for a new well, especially if the property is near a mapped site or an older land use.

Low yield and dry holes remain site risks even though the reported pump-yield sample is strong. Check well spacing, casing and grout, pump condition, septic setbacks, and the location of the proposed drainfield before placing a house. A Colorado DWR permit controls the approved use. Household-use wells may be exempt wells, but an over-appropriated basin can require an augmentation plan for added use.

Compare nearby records before buying a Holly lot

Start with the exact parcel, then compare permits and completion reports from nearby Holly wells and the surrounding areas of Hartman, Granada, Lamar, Sheridan Lake, and Brandon. Neighboring records can show the likely depth range, aquifer description, water level, and whether wells are used for household, stock, irrigation, or monitoring purposes.

For a purchase, make the well permit, recorded construction report, pump test, water-quality results, and septic approval part of your due diligence. For a new build, have a driller review access, the proposed well location, power, storage, trenching, and septic layout before excavation. In fractured or variable ground, do not assume the nearest well predicts your result. Get a written scope that explains depth allowances, testing, completion standards, and the response if the well does not meet the planned use.

What a new well costs in Holly, 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 (148 ft) would run roughly $11,180–$20,140. 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 Holly? 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 Holly 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.
