Towaoc, Colorado Well Depth, Yield, and Cost Guide

How deep are wells around Towaoc?

How much water do wells make near Towaoc?

Towaoc well depths reflect shallow local records, with exceptions

The median reported well depth near Towaoc is 85 feet. The middle half runs from 30 to 160 feet, so many wells are relatively shallow, but the spread matters when pricing a new hole. A driller should not bid every parcel from the median alone.

Depth records show 53% of wells under 100 feet, 37% from 100 to 300 feet, 9% from 300 to 600 feet, and 2% at 600 feet or more. The deepest recorded well is 1,108 feet. Most permits identify an unnamed or fractured-bedrock aquifer, with smaller numbers in the Mancos and Alluvial aquifers. Mixed sedimentary and alluvial ground can change quickly across a short distance.

Expected well yield around Towaoc

Reported yields are generally useful, but the sample is limited to 32 wells. The median pump yield is 10.9 gallons per minute, and the middle half is 4.9 to 15.0 gallons per minute.

The records show 3% of wells under 1 gallon per minute, 22% from 1 to 5, 38% from 5 to 15, and 38% above 15 gallons per minute. That distribution gives a buyer a reasonable local range, not a guarantee for a particular lot. A low-yield well may still serve a household with storage, while a higher-yield result provides more operating margin. Confirm the permitted use and test the well before relying on it for a home, livestock, or other demands.

Water levels near Towaoc look shallow, but the trend is limited

Only 5 wells in the records report a static water level, so this is the weakest part of the local dataset. Among those reports, the median depth to water is 12 feet, with the middle half from 6 to 25 feet.

That small sample does not establish a reliable water-table trend. The permit history spans the 1960s through the 2020s, with the newest permit issued in 2025, but permit age is not the same as a measured water-level series. Do not assume the water table is stable or declining based on these records alone. Ask for the well construction report, static level measurement, pumping test, and any current service information for the property under contract.

Who has drilled near Towaoc, and when

Permit activity near Towaoc is spread across several decades. The records show 1 permit in the 1960s, 18 in the 1970s, 57 in the 1980s, 54 in the 1990s, 41 in the 2000s, 96 in the 2010s, and 40 in the 2020s. The newest permit year is 2025.

The most active names in these records are Authorized (Pe, Pg), with 62 wells; Kilby'S Water Well Service (Kilby, Edward E), with 49; and Mcpherson Drilling Co. (Mcpherson, Billy G.), with 24. These counts describe permit records, not endorsements or current availability. Before hiring, verify licensing, insurance, references, and whether the driller has recent experience with the ground and access conditions on your parcel.

What a new Towaoc well may cost

For the mixed sedimentary and alluvial ground described in the cost model, the typical drilling rate is $50 to $75 per foot. At the local median depth of 85 feet, the drilled hole works out to about $4,200 to $6,400.

A finished system is more than the hole. Including the pump, pressure tank, trenching, and electrical work, the modeled total is about $10,200 to $18,400 at that median depth. A deeper-than-expected hole, difficult access, casing or grout requirements, water treatment, or extra trenching can move the price outside that range. Get a written bid that separates drilling, casing, grouting, development, pump equipment, electrical work, and testing.

Risks to check before building near Towaoc

Yield and contamination deserve separate review. Within about 10 miles, the mapped inventory includes 12 PFAS sampling or contamination sites, 5 historic mine features, and 1 EPA Superfund or cleanup site. Those mapped locations do not prove that a parcel's well is affected, but they are reasons to check the well history and obtain laboratory testing before closing.

Low-yield wells and dry holes remain possible, especially because most permits identify fractured-bedrock conditions and the records do not report results for every well. Confirm casing, grout, pump capacity, and water-quality testing. Locate the septic system and replacement area before finalizing a building site. Colorado well permits control allowed use; an exempt household-use well is subject to its permit terms and the 35-gpm exempt-well pumping limit. In an over-appropriated basin, an augmentation plan may be needed.

A practical plan for a Towaoc lot

Start with the neighboring wells closest to the parcel, giving priority to construction reports rather than map symbols alone. Compare their depths, yields, aquifer descriptions, static levels, and completion dates. The nearby communities of Cortez, Lewis, Dolores, Mancos, Marvel, and Hesperus can provide broader context, but conditions at the lot should control the decision.

For an existing home, inspect the pump, pressure tank, electrical components, storage, and treatment equipment, then collect a current water sample. For vacant land, confirm the water-rights path and permit before spending on excavation or house plans. Have a driller review access and a septic professional review soils and layout together. Keep a contingency for a deeper hole or lower yield instead of budgeting only from the 85-foot median.

Well permits by decade near Towaoc

What a new well costs in Towaoc, 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 (160 ft) would run roughly $14,000–$24,000. 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 Towaoc? 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 Towaoc 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.
