Colorado Well Finder › Wells by county › Eagle County › Avon
Buying land near Avon means evaluating a mountain well, not just checking whether a permit exists. Records within 5 miles show 242 permitted wells, with 94 recorded as constructed. Only 115 report total depth, 17 report pump yield, and 15 report static water level, so the database is useful for local patterns but cannot replace a site-specific well and septic review.
Most permits identify an unnamed or fractured-bedrock aquifer. That fits the granite and gneiss ground common around Avon, Edwards, Vail, Wolcott, Minturn, Fulford, and Red Cliff. Fractured rock can produce excellent water in one location and disappointing water a short distance away.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Avon. Not every permit reports every field; each statistic uses the wells that report it.

The median reported well depth near Avon is 67 feet. The middle half runs from 34 to 104 feet, meaning many drilling bids may cluster in that range, but it is not a guarantee for a new lot. The 90th percentile is 243 feet, and the deepest recorded well is 403 feet.
About 74% of wells are under 100 feet, while 17% fall between 100 and 300 feet and 9% fall between 300 and 600 feet. No recorded wells are 600 feet or deeper. In fractured granite and gneiss, depth is controlled by where water-bearing fractures occur, local slope and geology, and the actual drill site. A contractor should price the expected footage and explain the conditions that could push the hole deeper.
The reported yield numbers look favorable: the median is 200.0 gallons per minute, with a middle half from 30.0 to 400.0 gallons per minute. Every one of the 17 wells reporting a pump yield is listed above 15 gallons per minute. That suggests strong production in the reported records, but it does not mean a buyer should assume a new well will make 200.0 gallons per minute.
Yield reporting is sparse compared with the 242 permitted wells. Ask for the completion report, pump test, and current production history for any existing well. A household usually needs dependable supply and storage more than an unusually high test result. An exempt household-use well also has a 35 gallon-per-minute pumping limit, even when the aquifer could produce more.
Only 15 wells report a static water level. Those records have a median depth to water of 22 feet, with the middle half from 16 to 36 feet. For an existing well, that can help a driller estimate pumping conditions and help a buyer understand how much lift the pump may need.
The permit history runs from the 1950s through the newest permit in 2025, but permit counts by decade are not water-level measurements. They cannot establish that the water table is rising or dropping. Treat the 22-foot median as a limited local snapshot, not a guaranteed seasonal level. Ask for static levels, pumping levels, and dates from the specific well, especially if the property will need irrigation or more than ordinary household use.
Avon’s permit records include 1 permit from the 1950s, 4 from the 1960s, 28 from the 1970s, 34 from the 1980s, 16 from the 1990s, 42 from the 2000s, 31 from the 2010s, and 14 from the 2020s. The newest permit year is 2025. This is a long record of water development, not proof that every parcel can support a new well.
The most active drillers named in the records are Authorized (Pe, Pg), with 38 wells; Golden Eagle Drilling Corporation (Shelton, Joe Wayne), with 19; and Crandall, H A, with 12. Use neighboring completion reports as local evidence, but confirm the current contractor’s license, scope, casing and grout plan, pump test method, and permit requirements with Colorado DWR.
The cost model for Avon assumes fractured mountain bedrock, including granite and gneiss. The typical drilling rate is $65-$100 per foot. At the local median depth of 67 feet, the drilled hole is estimated at about $4,400-$6,700.
A finished well is a larger project. Including the pump, pressure tank, trenching, and electrical work, the estimate at that median depth is about $10,400-$18,700. Those figures are planning numbers, not a guaranteed bid. A deeper hole, difficult access, casing or grout requirements, water testing, or site work can change the total. Get a written proposal that separates drilling footage from completion equipment and identifies what happens if the hole produces too little water.
Fractured-bedrock wells can vary sharply from one lot to the next. Before closing, review the well permit, construction report, pump test, maintenance history, and recent lab results. The mapped area around Avon includes 12 PFAS sampling or contamination sites, 12 historic mine features, and 8 EPA Superfund or cleanup sites. These records do not prove contamination at a particular property, but they justify testing based on the site’s location and history.
Low yield and dry holes remain practical risks even where nearby wells perform well. Septic setbacks, driveway access, slope, winter conditions, trenching, and electrical routing can affect where the well and septic system can be installed. If the basin is over-appropriated, confirm whether an augmentation plan or other water-rights requirement applies to the proposed use.

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 (104 ft) would run roughly $12,760–$22,400. 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 Avon 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 reported depth near Avon is 67 feet, and the middle half runs from 34 to 104 feet. About 74% of recorded wells are under 100 feet. Depth still varies substantially in fractured granite and gneiss: the 90th percentile is 243 feet, and the deepest recorded well is 403 feet.
The typical drilling rate used for Avon’s fractured mountain bedrock is $65-$100 per foot. At the 67-foot median depth, the drilled hole is estimated at $4,400-$6,700. A finished well with pump, tank, trenching, and electrical work is estimated at $10,400-$18,700.
Only 17 wells in the records report a pump yield. Their median reported yield is 200.0 gallons per minute, with the middle half from 30.0 to 400.0 gallons per minute, and all reported yields are above 15 gallons per minute. That small sample does not guarantee a new well’s production.
Safety depends on the individual well and test results. The mapped area includes 12 PFAS sampling or contamination sites, 12 historic mine features, and 8 EPA Superfund or cleanup sites. These are reasons to test, not proof of contamination at your property. Review recent lab results and test a well before relying on it for drinking water.
The available records do not establish a declining water table. Only 15 wells report static water levels, with a median depth to water of 22 feet and a middle half from 16 to 36 feet. Permit counts by decade are not water-level measurements. For a purchase, request pumping and static-level records from the specific well.
