Colorado Well Finder › Wells by county › Prowers County
A shallow well is common in Prowers County, but it is not a safe assumption for every parcel. The median recorded depth is 100 feet, while the middle half runs from 45 to 300 feet. That spread matters when pricing land or asking for a drilling bid.
Colorado DWR records contain 3,837 permitted wells countywide, with 2,062 recorded as constructed. These records mix household, stock, irrigation and monitoring uses. For a purchase near Lamar, Holly, Wiley, Granada or Hartman, start with the county picture, then narrow the search to comparable neighboring wells.
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.

Among the 2,359 wells reporting depth, the median is 100 feet and the middle half spans 45-300 feet. Wells under 100 feet account for 49% of the depth mix, but the 90th-percentile depth is 505 feet. A bid based only on the county median can leave substantial deeper-drilling exposure.
The local ground includes alluvium and plains sedimentary rock. Permits name the Dakota aquifer on 171 wells and Southern High Plains on 139. Another 3,154 fall under the unnamed / fractured-bedrock label; that broad category does not establish the geology beneath your lot. Ask the driller to compare nearby completion logs and explain the expected water-bearing formation, casing requirements and price if drilling must continue deeper.
The 431 reported pump yields have a median of 38.0 gpm, with a middle half of 15.0-800.0 gpm. That unusually wide range needs context: irrigation represents 38% of permitted uses, compared with 21% domestic/household and 24% stock. The county yield figures are not a residential-only benchmark.
Reported yields are weighted toward stronger producers: 76% are in the 15+ gpm group, while 1% fall in the 1-5 gpm group and 0% are reported under 1 gpm. Those figures do not guarantee a productive hole or establish a dry-hole rate. For a home purchase, get a current pumping and recovery test. Confirm that the permit authorizes your intended use; tested output is not permission to pump without limits.
Only 138 wells report a static water level. Their median depth to water is 72 feet, and the middle half spans 13-188 feet below ground. Static level describes where water rests when the well is not pumping, not the bottom of the well or its sustained production.
Median measurements were 69 feet in the 1960s, 23 feet in the 2010s and 156 feet in the 2020s. The latest group is deeper, but this is not a steady countywide decline: different wells, locations and aquifers may be represented in each decade. Before calling a water table stable or falling on a particular property, look for repeated measurements from that well or comparable nearby wells in the same aquifer.
Recorded permit issuance reached 470 in the 1990s and 475 in the 2000s, followed by 323 in the 2010s. The 2020s contain 133 permits, with the newest permit dated 2025. That latest decade is incomplete, so the smaller count should not be read as a completed-decade comparison. Permits also do not necessarily represent completed, operating wells.
The most active driller labels in the records are Hoffman (Hoffman, Earl), with 326; Authorized (Pe, Pg), with 218; and Ark Valley Pump & Supply (Smith Jr., William), with 177. Treat these as historical record entries, not confirmation of current availability or licensing. The Authorized label especially needs checking against the original document before treating it as a drilling company.
The local cost model uses $35-$55 per foot for drilling through alluvium and plains sedimentary rock. At the 100-foot median depth, the drilled hole alone is about $3,500-$5,500. A finished well with pump, tank, trenching and electrical is modeled at $9,500-$17,500.
That finished range is a planning allowance, not a parcel-specific quote. With the middle half of depths reaching from 45 to 300 feet, depth uncertainty deserves explicit treatment in the contract. Ask what casing and grout are included, how pump selection is handled, and what changes the trenching or electrical price. Access conditions and the distance between the well and house also need to be settled before comparing bids.
The environmental map identifies 16 PFAS sampling/contamination sites, 2 historic mine features and 5 EPA Superfund/cleanup sites within about 10 miles. A mapped site does not prove that a particular well is contaminated, and a sampling location is not necessarily a confirmed contamination source. It is a reason to review the underlying records and choose testing appropriate to the property.
Have the water tested rather than relying on taste or clarity. Inspect the wellhead, casing condition and available grout documentation. Reported yields do not establish dry-hole risk, so discuss unsuccessful drilling terms before signing. For a new build, coordinate the well location with septic siting, drainage, access and the house layout before committing to excavation.
For a parcel around Granada or Hartman, nearby wells in a similar setting are more useful than the county median alone. Compare their depths, completion logs, aquifer descriptions and tested yields. Kiowa County, Bent County and Baca County can provide regional context, but crossing a county line does not make a well a good geological match.
Before buying, obtain the DWR permit and match its location and allowed uses to the property and your plans. Do not assume a household-use permit allows irrigation or every proposed outdoor use. In an over-appropriated basin, uses outside an available exemption may require an augmentation plan. Make permit review, water-quality results, production testing and a coordinated well-and-septic layout part of the buying 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 (300 ft) would run roughly $16,500–$28,500. 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 Prowers 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.

The median recorded depth is 100 feet, based on 2,359 wells reporting depth. The middle half runs from 45 to 300 feet, and the 90th percentile is 505 feet. Use nearby completion logs to narrow that range for a parcel; the county median is a starting point, not a promised drilling depth.
The local model puts drilling at $35-$55 per foot. At the 100-foot median depth, the hole alone is about $3,500-$5,500, while a finished well with pump, tank, trenching and electrical is about $9,500-$17,500. Get a written scope covering casing, grout, access and deeper-drilling charges before treating those figures as your budget.
The median reported pump yield is 38.0 gpm, and the middle half spans 15.0-800.0 gpm. These figures come from 431 yield reports and include agricultural wells; irrigation accounts for 38% of permitted uses. A household buyer should rely on a current pumping and recovery test, not assume the county median applies to the property.
County permit records cannot establish whether an individual well is safe. The map shows 16 PFAS sampling/contamination sites and 5 EPA Superfund/cleanup sites within about 10 miles, but proximity alone does not prove a well is affected. Review relevant site records, inspect the wellhead and obtain laboratory testing selected for the property's conditions.
The available measurements do not establish a steady countywide decline. Median static levels were 69 feet below ground in the 1960s, 23 feet in the 2010s and 156 feet in the 2020s. Only 138 wells report static levels, and the decade groups may represent different wells. Repeated measurements from comparable wells are needed to assess a local trend.
