Colorado Well Finder › Wells by county › Logan County
A well budget around Sterling, Merino or Fleming should start with nearby completion records, not a countywide promise. Logan County's recorded median depth is 88 feet, but the middle half runs from 60 to 180 feet—enough variation to change a drilling bid substantially.
Colorado DWR records contain 9,230 permitted wells in the county, with 5,887 recorded as constructed. These figures cover all permitted uses, not just household wells, and a permit record alone does not establish a working water supply.
Figures are computed from Colorado Division of Water Resources permit records for all permitted wells in the county. Not every permit reports every field; each statistic uses the wells that report it.

Of the 6,364 Logan County wells reporting depth, the median is 88 feet. The middle half spans 60–180 feet, and 56% are under 100 feet. That makes relatively shallow drilling common, but it does not justify pricing every lot at the median. The 90th-percentile depth is 320 feet.
Local alluvium and plains sedimentary rock influence where usable water is encountered. Permits name Ogallala for 414 wells and Alluvial for 208. Another 8,295 fall under an unnamed / fractured-bedrock label; that broad record category is not proof of granite beneath a particular parcel. Around Atwood or Peetz, compare nearby logs and water-bearing intervals before setting a bid depth.
The 1,809 wells with reported pump yields have a 15 gpm median, with the middle half at 15–20 gpm. The reported distribution places 81% at 15 gpm or above and 2% in the 1–5 gpm band. Those figures are encouraging for a household buyer, but they combine different well uses and aquifers.
The share below 1 gpm is reported as 0%; that is not a guarantee against a weak well or an unsuccessful hole. A recorded pump yield does not establish present-day sustained production. Have an existing well tested for drawdown and recovery, and ask how its output fits household demand, storage and any legally permitted outdoor use.
Static water level is the depth to water while the well is resting, not the bottom of the hole. Among 473 reporting wells, the median is 44 feet below ground, and the middle half is 16–131 feet. Those countywide figures should not be subtracted from a typical total depth to estimate a particular well's available water.
Recent decade medians become deeper: 27 feet in the 2000s, 60 in the 2010s and 73 in the 2020s. That suggests concern about declining levels, but it is not a repeat-measurement trend for the same wells. Earlier medians fluctuate. Ask for dated measurements from the property and neighboring wells before concluding how much local water levels have changed.
Logan County's permit history includes 313 permits in the 1950s, 1,281 in the 1990s and 1,423 in the 2000s. Records show 881 in the 2010s and 460 in the 2020s, with the newest permit dated 2026. The current decade is incomplete, and issued permits are not the same as completed wells.
The leading drillers by recorded count are Stewart Drilling Co. (Stewart, Dennis W.) with 1,240, Canfield, Leslie George with 704, and M&S Drilling, Inc. (Monheiser, Mark) with 480. These are historical totals, not confirmation of current availability. Use the names on nearby completion reports to identify relevant local experience, then verify present licensing, service area and scheduling directly.
The supplied cost model uses $35–$55 per foot for Logan County's alluvium and plains sedimentary rock. At the 88-foot median depth, that puts the drilled hole at about $3,100–$4,800. A finished well with pump, tank, trenching and electrical is modeled at $9,100–$16,800.
These are planning figures, not a parcel-specific quote. With the middle half of recorded depths spanning 60–180 feet, extra footage can materially change the drilling portion. Ask the contractor to spell out casing, grout, development, testing and any exclusions. For a new build near Crook or Padroni, have the bid account for access and the actual route between the well, power supply and house.
The environmental mapping lists 23 PFAS sampling/contamination sites and 6 EPA Superfund/cleanup sites within about 10 miles. A mapped sampling site is not proof that a nearby domestic well is contaminated, and proximity alone cannot establish safety. Review the site details and obtain property-specific laboratory testing; ask local health staff whether PFAS testing is appropriate alongside bacteria and nitrate testing.
The favorable reported yields do not eliminate dry-hole or low-yield risk on untested land. Check neighboring logs and clarify how the drilling agreement handles an unsuccessful hole. Before finalizing a house location, coordinate the well, septic system, drainage, access and required setbacks so the buildable layout works as a whole.
Start with the exact parcel and the actual well permit. Logan County's recorded use mix includes 50% domestic/household, 33% stock and 15% irrigation, but those countywide categories do not tell you what your permit allows. Confirm authorized uses with DWR, including any proposed livestock, lawn or garden demand. A household-use permit should not be treated as unrestricted outdoor water.
For an existing home, request the completion report, pump information, recent water-quality results and a production test. For vacant land, review neighboring wells in the same local setting and confirm permit eligibility before committing to construction. In an over-appropriated basin, uses outside an applicable exemption may require augmentation. Resolve water authorization, drilling access and septic feasibility before setting the house footprint.

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 (180 ft) would run roughly $12,300–$21,900. 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 Logan County 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.

Logan County's median recorded well depth is 88 feet, and the middle half runs from 60 to 180 feet. These figures come from 6,364 wells reporting depth across all permitted uses. Nearby completion logs are more useful for a specific lot because local sediment layers and water-bearing intervals can change the required drilling depth.
The planning model uses $35–$55 per foot. At the county's 88-foot median depth, the drilled hole is about $3,100–$4,800, while a finished well with pump, tank, trenching and electrical is about $9,100–$16,800. Get a written site-specific bid that identifies casing, grout, testing, access requirements and exclusions.
Among 1,809 wells with reported pump yields, the median is 15 gpm and the middle half is 15–20 gpm. The records cover household, agricultural and other uses, so they are not a household-only forecast. For a purchase, test the actual well's sustained output, drawdown and recovery rather than relying solely on its historical reported yield.
The county statistics cannot establish whether a particular well is safe. Mapping lists 23 PFAS sampling/contamination sites and 6 EPA Superfund/cleanup sites within about 10 miles, but those locations do not prove contamination at your property. Obtain laboratory testing for the well and ask local health staff which additional tests fit the site's surroundings.
Recent recorded decade medians are deeper: 27 feet below ground in the 2000s, 60 in the 2010s and 73 in the 2020s. That raises concern, but the figures represent different groups of measured wells, not necessarily repeated readings at the same locations. Review dated water levels from the property and nearby wells to assess local change.
