Colorado Well Finder › Wells by county › Boulder County › Eldorado Springs
Buying land or a home in Eldorado Springs means looking beyond whether a property has a well permit. The records within five miles include 3,866 Colorado DWR permits, but only 1,487 are recorded as constructed, 1,685 report total depth, 324 report pump yield, and 73 report static water level. That uneven reporting matters. The available data shows a shallow median depth of 49 feet, a median reported yield of 10.0 gallons per minute, and a median static water level of 12 feet below the surface. Those figures are useful for planning, but they do not guarantee what a new well will find on a particular lot.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Eldorado Springs. Not every permit reports every field; each statistic uses the wells that report it.

The reported median well depth near Eldorado Springs is 49 feet. The middle half runs from 20 to 300 feet, so nearby wells vary sharply even before considering the deepest record of 1,989 feet. Depth distribution tells the same story: 56% are under 100 feet, 17% are 100 to 300 feet, 22% are 300 to 600 feet, and 5% exceed 600 feet.
For a drilling bid, do not use the 49-foot median as a promise. It is a starting point for a shallow local pattern, while the 20-to-300-foot middle range shows how much uncertainty remains. Permits identify many wells in unnamed or fractured-bedrock aquifers, along with Alluvial and Laramie Fox Hills entries. Fractured rock can change quickly from lot to lot.
Reported well yield is strongest in the 5-to-15-gallon-per-minute range. The median is 10.0 gallons per minute, with the middle half from 6.5 to 13.3. A further 21% report more than 15 gallons per minute, while 15% fall between 1 and 5 gallons per minute and 1% are under 1 gallon per minute.
That low-yield tail is small, but it is important to a buyer because a property may still need storage and careful demand planning. A yield test is not the same as a guarantee of household performance during every season. Review the well construction report, pump test, permitted use, and any storage or treatment equipment. An exempt household-use well is generally subject to Colorado’s 35-gallon-per-minute pumping limit.
The reported median static water level is 12 feet below the surface, with the middle half from 6 to 40 feet. That is a relatively shallow measured water level in the available records, but the sample is limited to 73 wells reporting static water level. A nearby measurement is useful context, not a substitute for testing the well you may buy.
The decade series shows a median of 8 feet below the surface in the 2010s and 10 feet in the 2020s. That is a deeper reported median in the newer decade, but the facts do not establish a long-term dropping water table. Measurement dates, locations, well construction, and the small reporting pool can all affect the comparison. Ask for current water-level information during due diligence.
Colorado DWR records show permits issued into the 2020s, with the newest permit year listed as 2025. There are 37 permits from the 2020s in the supplied decade summary. The record is not a complete list of active production wells: monitoring use accounts for 47% of the use mix, domestic or household use for 35%, stock for 2%, and irrigation for 1%.
The most active drillers named in these records are Authorized (Pe, Pg), with 1,002 entries; Boyles Bros. Drilling Co. (Lensch, George E), with 410; and Ground Water Systems Inc (Wilson, Richard R.), with 182. Those counts describe permit records, not endorsements or current availability. Confirm licensing, insurance, scope, and references before hiring anyone.
The local drilling model uses a typical rate of $50 to $70 per foot in Denver Basin sedimentary bedrock. At the 49-foot median depth, the drilled hole works out to about $2,400 to $3,400. That is only the hole. A finished well with pump, pressure tank, trenching, and electrical is modeled at about $8,400 to $15,400.
Your bid can move outside that range if the site requires substantially more depth, difficult access, extra casing or grout, rock excavation, or specialized equipment. The depth distribution is the reason to ask how a contractor handles a dry hole or an unsuccessful interval before work starts. Get the drilling, completion, pump, electrical, trenching, testing, and permit responsibilities written into the proposal.
Yield and depth are not the only concerns. Within about ten miles, the mapped environment includes 193 PFAS sampling or contamination sites, 326 historic mine features, and 23 EPA Superfund or cleanup sites. These maps do not prove that a particular parcel is contaminated, but they justify a records search and water testing appropriate to the property’s location and history.
Ask about dry holes, low-yield wells, casing, grout, and the condition of the pump system. Confirm that the well permit allows the intended use and that the septic layout can meet setbacks from the well, property lines, surface water, and the proposed building. In mountain terrain, access for a rig, trenching route, slope stability, and winter construction can affect both feasibility and cost.
Start with the well permit and construction report, then compare the property with nearby records in Paragon Estates, Superior, Boulder, Louisville, Valmont, and Coal Creek. A cluster of nearby wells can help frame expected depth and yield, but it cannot replace a site-specific evaluation, particularly where fractured-bedrock conditions are involved.
For an existing home, inspect the pump, pressure tank, wiring, storage, treatment equipment, and recent water-quality results. For vacant land, have a driller and septic professional review access, the proposed building envelope, and the likely well and septic locations before closing. Keep contingencies for well yield, water quality, permits, and septic approval. The numbers here are planning evidence, not a promise of water on any individual parcel.

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 (300 ft) would run roughly $21,000–$33,000. 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 Eldorado Springs 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 within five miles of Eldorado Springs is 49 feet. The middle half runs from 20 to 300 feet, and the deepest record is 1,989 feet. Most are under 100 feet, but 22% are 300 to 600 feet and 5% exceed 600 feet. A local driller should price the lot-specific uncertainty.
The drilling model uses $50 to $70 per foot. At the 49-foot median depth, the drilled hole is about $2,400 to $3,400. A finished well including pump, tank, trenching, and electrical is modeled at about $8,400 to $15,400. Difficult access, greater depth, casing, grout, and dry-hole risk can change the bid.
The median reported yield is 10.0 gallons per minute, with the middle half from 6.5 to 13.3. Most reported wells, 63%, produce 5 to 15 gallons per minute. However, 15% report 1 to 5 gallons per minute and 1% are under 1 gallon per minute, so review the actual well test before relying on the supply.
The records alone cannot establish that a property’s water is safe. Within about ten miles are 193 PFAS sampling or contamination sites, 326 historic mine features, and 23 EPA Superfund or cleanup sites. Those facts support property-specific testing and a review of nearby land uses, mine history, well construction, and treatment needs before purchase.
The reported median static water level was 8 feet below the surface in the 2010s and 10 feet in the 2020s. That newer value is deeper, but the available facts do not prove a declining water table because only 73 wells report static water level and the measurements may differ by location, construction, and timing. Request current measurements for the property.
