What to Expect From a Well in Delta County

Colorado Well FinderWells by county › Delta County

A typical recorded Delta County well is relatively shallow, but that does not make every parcel an easy drilling job. The countywide median depth is 90 feet, and the median reported yield is 15 gpm. Ground conditions, legal water use and the location of a productive water-bearing layer still decide what works on your lot.

Colorado DWR records contain 3,887 permitted wells across Delta County, with 2,264 recorded as constructed. Use those records to narrow your search around Delta, Cedaredge, Paonia, Hotchkiss, Lazear, Orchard City or Crawford—not as a guarantee that your property will match the county average.

Depth Near Delta Is a Starting Point, Not a Bid

Among the 2,371 wells reporting depth, the median is 90 feet and the middle half fall between 45 and 150 feet. That range is useful for budgeting: ask a driller to explain how the price changes if the productive interval is deeper than expected. The 90th-percentile depth is 230 feet, so the median is not a sensible fixed-depth promise.

Delta County has mixed sedimentary and alluvial ground. Most permits leave the aquifer unnamed or use a fractured-bedrock designation; smaller groups name Mesa Verde Group or Mancos. Those broad labels do not identify the productive layer on a particular lot. Compare nearby completion logs with similar terrain before carrying a depth assumption from Paonia to Cedaredge or Crawford.

Reported Yields Are Encouraging, but Test the Well

The 787 records with pump yields show a 15 gpm median, with the middle half between 10 and 15 gpm. That is an encouraging starting point for household supply, but a recorded pumping rate does not establish dependable production through changing conditions or prolonged use.

The reported share under 1 gpm is 0%; that is not proof that low-yield or unsuccessful holes do not occur. Another 10% fall in the 1–5 gpm category. A buyer considering one of those wells should pay particular attention to recovery and storage needs. Obtain a current pumping and recovery test, then size the pump and any storage around demonstrated supply rather than the county median.

Delta County Water-Level Records Show Deeper Readings

Static water level is the depth to water while the well is resting, not the finished depth of the hole. Delta County's 287 reported measurements have a 25-foot median, with the middle half between 9 and 72 feet. A shallow resting level does not tell you how far the water will draw down while pumping.

The decade medians move deeper: 10 feet below ground in the 2000s, 15 feet in the 2010s and 36 feet in the 2020s. That pattern is consistent with declining groundwater levels, but these are not necessarily repeat measurements from the same wells. Different locations and measurement seasons can affect the comparison. For a purchase, prioritize the property's own water-level and pumping history.

The County's Permit History and Recorded Drillers

The busiest listed permit decade was the 2000s, with 1,205 permits, compared with 633 in the 1990s and 444 in the 2010s. The records include 306 permits from the 2020s, with the newest permit dated 2025. That latest decade is incomplete, so its total should not be treated as a full-decade comparison.

The most active drillers in the records are Bill Kissner Drilling Inc (576), Wildcat Drilling & Pump, Inc. (524) and K. W. Anderson Drilling (218). These are historical record counts, not confirmation of current availability. Domestic/household use appears on 68% of permits, but the county's use mix does not establish what your particular permit allows.

Budgeting a New Delta County Well Beyond the Hole

For the county's mixed sedimentary and alluvial ground, the cost model uses $50–$75 per foot. At the 90-foot median depth, that puts the drilled hole at about $4,500–$6,800. A finished well with pump, tank, trenching and electrical is modeled at $10,500–$18,800.

Treat those amounts as planning figures, not a parcel-specific quote. The middle-half depth range of 45–150 feet leaves meaningful room for the drilling bill to change. Access, casing and grout requirements, pump selection, and the route to the house also matter. Ask for a written scope separating drilling from completion equipment and site work, with clear terms for deeper drilling or an unsuccessful hole.

Check Water Quality and Leave Room for Septic

The environmental mapping identifies 31 PFAS sampling/contamination sites, 62 historic mine features and 12 EPA Superfund/cleanup sites within about 10 miles. These are screening flags, not evidence that a particular Delta County well is contaminated. A sampling location may not represent a confirmed contamination source.

Before closing, obtain laboratory testing for drinking-water suitability and ask the local health authority which additional tests fit the property's setting. Review casing, grout and wellhead drainage as well as the water sample. A usable building site also needs a compliant septic layout and protected well location. Do not assume a favorable reported yield eliminates dry-hole risk, or that a large parcel automatically provides a workable house, septic and well arrangement.

Before Buying in Hotchkiss, Orchard City or Crawford

Start with the actual well permit, completion report and parcel location. Confirm that the existing well belongs to the property and that its authorized uses match your plans. A household-use permit is not blanket permission for irrigation or livestock watering. Ask Colorado DWR about new-permit eligibility and any applicable augmentation requirements before committing to an unserved lot.

Next, compare nearby wells around the specific town and terrain—not just the Delta County median. Make the purchase decision around documented yield, current water quality, legal use and a realistic site plan. For a new build, have the driller and site contractor review rig access, the driveway, septic placement, utility trenching and the proposed house location together before those locations become expensive to change.

Buying land near Delta County? 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 Delta 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.

Common questions about wells in Delta County

How deep are wells in Delta County, Colorado?

The median recorded depth is 90 feet, and the middle half of wells are 45–150 feet deep. The 90th-percentile depth is 230 feet. Those figures come from 2,371 depth records across Delta County. Nearby completion logs in similar ground are a better guide for a particular lot than the county median alone.

How much does it cost to drill a well in Delta County?

The local model uses $50–$75 per foot for mixed sedimentary and alluvial ground. At the 90-foot median depth, drilling the hole is about $4,500–$6,800. A finished well with pump, tank, trenching and electrical is about $10,500–$18,800. Get a site-specific scope covering access, casing, completion work and charges if deeper drilling is needed.

How much water do wells produce in Delta County?

Reported pump yields have a 15 gpm median, with the middle half between 10 and 15 gpm. These figures cover 787 records, not every permitted well. The 1–5 gpm category accounts for 10% of reported yields. Before buying, use a current pumping and recovery test to assess supply and potential storage needs.

Is well water safe to drink in Delta County?

County permit records cannot establish whether an individual well is safe. Mapping lists 31 PFAS sampling/contamination sites, 62 historic mine features and 12 EPA Superfund/cleanup sites within about 10 miles, but proximity alone does not prove contamination. Have the water tested by a laboratory and use the property's setting to guide additional testing.

Is the water table dropping in Delta County?

Recorded decade medians became deeper, from 10 feet below ground in the 2000s to 15 feet in the 2010s and 36 feet in the 2020s. That suggests a concern worth investigating, not a proven decline at every property. The records may represent different wells and seasons; review repeat measurements from the well you plan to use.
