Avondale, Colorado Well Depth, Yield, and Cost

How deep are wells around Avondale?

How much water do wells make near Avondale?

How deep are Avondale wells?

The median reported well depth around Avondale is 41 feet. The middle half runs from 32 to 50 feet, and 90% of reported wells are no deeper than 59 feet. The depth mix reinforces that pattern: 98% are under 100 feet, 1% fall between 100 and 300 feet, none are recorded between 300 and 600 feet, and 1% are 600 feet or deeper.

For a driller's bid, that means a typical Avondale hole is shallow, but the deepest record reaches 2,150 feet. The broad outlier range is a reminder that geology and the intended water source control the final design. Most permits name an unnamed or fractured-bedrock aquifer, while 55 name alluvial water. No Denver Basin aquifer wells appear in these records.

What Avondale wells produce

Reported pump yields are generally favorable. The median is 30.0 gallons per minute, with the middle half ranging from 15.0 to 367.5 gallons per minute. Eighty percent of the reported wells produce more than 15 gallons per minute. Seventeen percent fall between 5 and 15 gallons per minute, while 1% are between 1 and 5 gallons per minute and 1% are under 1 gallon per minute.

For a buyer, the small share under 1 gallon per minute is encouraging, but the sample is limited to 71 yield reports. A well's yield test is more useful than the neighborhood median. Ask for the completion report, pump test information, storage capacity, and any restrictions on the permit. An exempt household-use well also remains subject to Colorado rules, including the 35 gpm exempt-well pumping limit.

Avondale water levels and the reported trend

Reported static water levels are shallow. The median depth to water is 30 feet, and the middle half falls between 26 and 33 feet below the surface. That is useful when planning a pump setting, trenching, and electrical work, but it is not the same as a guaranteed water level on an untested lot.

The decade figures do not show a simple dropping water table in these records. The median measured water level was 32 feet below surface in the 2010s and 21 feet in the 2020s, meaning the later reported measurements were shallower. Only 66 wells report static water level, and measurement conditions vary, so treat this as a record-based signal rather than a basin-wide conclusion. Seasonal conditions, pumping, and well location can all affect a reading.

Who has drilled near Avondale, and when

Permit activity spans several generations. The records show 103 permits from the 1950s, 96 from the 1960s, 88 from the 1970s, 68 from the 1980s, 350 from the 1990s, 660 from the 2000s, 134 from the 2010s, and 60 from the 2020s. The newest permit year is 2025. A large share of the local inventory was permitted in the 1990s and 2000s, so many nearby wells may not represent current construction standards or current site conditions.

The most active names in the records are Authorized (Pe, Pg), with 585 wells; Lang Equipment, LLC (Lang, Alan F.), with 133; and Layne Western Company Inc. (Larson, Carl), with 93. Check the actual permit and completion documents rather than relying only on a driller name. DWR records can clarify use, construction, and reported performance.

What a new well costs in Avondale

For Avondale's alluvium and plains sedimentary rock, the drilling model uses a typical rate of $35-$55 per foot. At the local median depth of 41 feet, the drilled hole works out to about $1,400-$2,300. That is the hole only, not the complete water system.

A finished well with pump, pressure tank, trenching, and electrical is estimated at about $7,400-$14,300. A bid can move outside that range if the site needs unusual casing or grout, difficult access, extra trenching, treatment equipment, or a deeper-than-typical hole. Get the scope in writing and ask which items are included. Permit requirements, water rights, and an augmentation plan may also affect a proposed use in an over-appropriated basin.

Risks to check before buying or building

Low yield is not the main pattern in the reported Avondale data, but a buyer should still verify the individual well. The records include 1% under 1 gallon per minute and 1% between 1 and 5 gallons per minute, and many permits do not report a yield at all. Dry holes and poor production can occur even where neighboring wells perform well, especially where fractured material controls the water-bearing zone.

Water quality deserves separate attention. Within about 10 miles, the map includes 16 PFAS sampling or contamination sites and 7 EPA Superfund or cleanup sites. There are no historic mine features mapped in that area. Test an existing well for ordinary drinking-water concerns and site-specific contaminants, and inspect casing, grout, storage, and septic separation before relying on the water for a home.

A practical Avondale lot checklist

Before closing, pull the nearby permits and compare depth, use, yield, water level, aquifer description, and construction details. Boone is about 5 miles away, Vineland about 6 miles, Blende about 12 miles, Salt Creek about 13 miles, Pueblo about 14 miles, and Fowler about 19 miles; those places can provide broader context, but Avondale-area wells should carry the most weight.

For a build, confirm the well permit and intended use with Colorado DWR, locate the septic area, and leave room for access by a drilling rig and service truck. Plan for sampling before occupancy. If the property will add household demand, livestock, irrigation, or other uses, confirm that the permit allows it. A local contractor can also evaluate driveway access, trench routes, drainage, and the ground conditions that will affect the final bid.

Well permits by decade near Avondale

What a new well costs in Avondale, 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 (50 ft) would run roughly $7,750–$14,750. 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 Avondale? 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 Avondale 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.
