Colorado Well Finder › Wells by county › San Juan County › Silverton
Well records within five miles of Silverton show a mountain drilling area with relatively shallow reported wells but fractured-bedrock conditions. The median recorded depth is 92 feet, and the middle half runs from 56 to 134 feet. That does not make every lot easy to drill. Bedrock fractures control where water is found, and nearby records include wells as deep as 325 feet.
The database contains 109 permitted wells, with 46 recorded as constructed. Only 11 report a pump yield and 11 report a static water level, so use these figures as local guidance rather than a guarantee for a particular parcel.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Silverton. Not every permit reports every field; each statistic uses the wells that report it.

Silverton’s reported well depths are generally modest: 60% are under 100 feet, while 35% fall between 100 and 300 feet. The middle half, from 56 to 134 feet, is the most useful range when discussing an initial drilling bid. A driller should still price the work with uncertainty because the local permits identify an unnamed or fractured-bedrock aquifer for 100 wells, compared with 5 alluvial wells.
Fractured granite and gneiss can produce water along narrow cracks rather than through a consistent, shallow layer. One nearby lot may work at a shallow depth while another requires a deeper hole. The deepest recorded well is 325 feet, so a bid should explain the footage rate, casing and grout assumptions, and what happens if the hole must continue.
The 11 Silverton-area records that report pump yield show a median of 12.0 gallons per minute. The middle half is 8.5 to 15.0 gallons per minute. Among those reported wells, 45% produce between 5 and 15 gallons per minute, and 36% report more than 15 gallons per minute. No reported well is under 1 gallon per minute; 18% fall between 1 and 5 gallons per minute.
That is encouraging for domestic use, but it is not a promise for an untested parcel. Ask for the well completion report, pumping test details, storage tank size, and recovery information. A well’s practical supply depends on both its flow and the amount of water stored in the casing and tank.
Only 11 permits report a static water level. Their median depth to water is 10 feet, with the middle half from 4 to 42 feet. Those measurements suggest that some completed wells encounter water relatively close to the surface, but they do not establish the water level beneath every Silverton property.
The permit counts rise across the record: 2 in the 1970s, 8 in the 1980s, 11 in the 1990s, 12 in the 2000s, 30 in the 2010s, and 37 in the 2020s. That is permit activity, not a water-table trend. The available static-level data are too limited to claim that groundwater is dropping or rising.
The newest permit in this search is from 2025, and most recent activity appears in the 2010s and 2020s. The most common driller entry is Authorized (Pe, Pg), associated with 26 records. Mccracken Well Drilling Inc (Mccracken, Alan E.) appears on 8, and Cascade Drilling, Lp (Cain, Shawn) appears on 6.
Those records can help you identify contractors familiar with the area, but a permit list is not a performance guarantee. Confirm current licensing, insurance, availability, and what each bid includes. Before construction, check Colorado DWR requirements for the intended use. Household wells may be exempt wells, but the permit conditions and local water-rights situation still matter.
For fractured mountain bedrock, the local drilling model uses $65 to $100 per foot. At the 92-foot median depth, the drilled hole works out to about $6,000 to $9,200. A finished system, including pump, pressure tank, trenching, and electrical, is modeled at about $12,000 to $21,200.
That is a planning range, not a fixed quote. A hole near the 325-foot record depth would carry much more drilling footage before equipment and site work are added. Ask whether the proposal includes casing, grout, development, water testing, permits, mobilization, difficult access, and a dry-hole or low-yield policy. The cost of the access route can also change the final number on a steep mountain lot.
Environmental screening matters around Silverton. Mapping within about 10 miles shows 6 PFAS sampling or contamination sites, 7,413 historic mine features, and 21 EPA Superfund or cleanup sites. These mapped features do not prove contamination at a specific parcel, but they are reasons to review site history, test existing water, and ask the Colorado Department of Public Health and Environment or local authorities about nearby concerns.
Low yield and a dry hole remain possible in fractured rock even though the reported yield sample is favorable. Confirm septic setbacks, replacement-area requirements, driveway access for a drill rig, building envelope, and winter access before closing. For a lot near Ophir, Telluride, Mountain Village, Ouray, Portland, or Rico, compare nearby well reports rather than relying on a countywide assumption.
Start with the recorded wells closest to the parcel, especially completed wells with depth, yield, and static-level information. Then have a licensed driller review geology, access, likely siting, and the permit path. A shallow median depth can make early budgeting easier, but it should not be treated as a guaranteed drilling depth.
For a home, confirm that the planned well can serve household demand and that the septic system can fit with required setbacks. If the property is intended for more than ordinary exempt household use, review water rights and any augmentation-plan requirements for the basin. Before you make the purchase decision, obtain a written drilling estimate, verify the well permit status, test existing water when available, and keep enough contingency for deeper drilling or a replacement location.

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 (134 ft) would run roughly $14,710–$25,400. 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 Silverton 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 well depth within five miles of Silverton is 92 feet. The middle half runs from 56 to 134 feet, and 60% of wells are under 100 feet. Depth is not consistent across mountain bedrock, however; the deepest recorded well reaches 325 feet.
The drilling model uses $65 to $100 per foot in fractured mountain bedrock. At the 92-foot median depth, the drilled hole is estimated at about $6,000 to $9,200. A finished system with pump, tank, trenching, and electrical is estimated at $12,000 to $21,200.
Among the 11 local records reporting pump yield, the median is 12.0 gallons per minute, with a middle half of 8.5 to 15.0 gallons per minute. The sample is limited, so it cannot guarantee the yield on a particular lot. Request a pumping and recovery test before relying on a reported rate.
Safety depends on the individual well and its surroundings. Mapping within about 10 miles identifies 6 PFAS sites, 7,413 historic mine features, and 21 EPA cleanup sites. Those locations do not prove a problem at your property. Test the water for relevant contaminants and review well construction, septic separation, and site history.
Yes. The records include permits through 2025. They show 37 permits issued in the 2020s and 30 in the 2010s. The most frequent driller entry is Authorized (Pe, Pg), with 26 records, followed by Mccracken Well Drilling Inc with 8 and Cascade Drilling, Lp with 6.
