Colorado Well Finder › Wells by county › Boulder County › Crisman
Crisman is a mountain well area where most permitted wells draw from unnamed fractured-bedrock aquifers. Records within five miles show a 285-foot median well depth, a median reported yield of 7.0 gallons per minute, and a median static water level 60 feet below the surface.
Those figures are useful for planning, but they do not guarantee what a particular lot will produce. Mountain bedrock can change quickly across short distances. Before buying or building near Mountain Meadows, Sunshine, Tall Timber, Seven Hills, Sugarloaf, or Gold Hill, review nearby permits, well construction records, water levels, and the legal water use allowed for the property.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Crisman. Not every permit reports every field; each statistic uses the wells that report it.

Among the permitted wells near Crisman that report total depth, the median is 285 feet. The middle half runs from 155 to 425 feet, so a driller bidding a new well here should not assume every hole will resemble a shallow foothills well. The 90th-percentile depth is 600 feet, and the deepest record reaches 1,402 feet.
Depth records are spread across the area: 16% are under 100 feet, 35% fall between 100 and 300 feet, 37% between 300 and 600 feet, and 12% are 600 feet or deeper. Most permits name unnamed or fractured-bedrock aquifers. Granite and gneiss fractures control where water is found, so the final depth can differ substantially between neighboring lots.
The reported median yield is 7.0 gallons per minute, with the middle half between 5.0 and 10.0 gallons per minute. That is generally a workable range for a household well, but the pumping test and storage system still matter. A well's reported yield is not the same as unlimited daily water use.
Only 3% of reported yields are under 1 gallon per minute. Another 18% are between 1 and 5 gallons per minute, while 70% are between 5 and 15 gallons per minute and 10% exceed 15 gallons per minute. A buyer should ask how long the test ran, whether the result was measured after drilling, and how the home will manage storage during peak demand.
Static water level means the depth from the ground surface down to standing water in the well. The local median is 60 feet, with the middle half between 18 and 100 feet. That range affects pump setting, electrical planning, and the amount of lift a system must handle.
The decade figures vary rather than forming a simple, steady decline: 30 feet in the 1960s, 40 feet in the 1970s, 68 feet in the 1980s, 6 feet in the 2000s, 90 feet in the 2010s, and 100 feet in the 2020s. Because only 125 wells report static water levels, the series is a warning to check the individual well and nearby records, not proof of one uniform water-table trend.
Colorado DWR records show permits from the 1950s through the newest permit year, 2025. Permit activity was highest in the 1970s, with 861 permits, followed by 552 in the 1980s, 557 in the 1990s, 300 in the 2000s, 186 in the 2010s, and 114 in the 2020s. The records include 3,765 permitted wells, with 2,480 recorded as constructed.
The most frequent driller name is Ground Water Systems Inc. (Wilson, Richard R.), appearing on 862 records. Ingram Drilling Inc. (Ingram, Stephen E.) appears on 268, and Norris & Sons (Norris, T A) on 201. These records show local history, not an endorsement. Confirm current licensing, insurance, availability, and what each bid includes.
Fractured granite and gneiss make drilling cost sensitive to depth and ground conditions. The local cost model uses $65-$100 per foot. At the 285-foot median depth, the drilled hole works out to about $18,500-$28,500.
A finished system, including the pump, pressure tank, trenching, and electrical work, is modeled at about $24,500-$40,500 at that median depth. Treat this as a planning range, not a guaranteed quote. Ask the driller to separate drilling, casing and grout, pump equipment, testing, trenching, electrical work, and any difficult access or extra-depth charges. A low initial bid can change if the hole must continue through unproductive bedrock.
Low yield and dry holes are the main physical risks in fractured mountain rock. The records show that most reported wells produce between 5 and 15 gallons per minute, but some produce under 1 gallon per minute. A buyer should obtain the well permit, construction report, yield test, water-quality results, and maintenance history rather than relying on a neighbor's experience.
Environmental review also matters. Within about 10 miles, the mapped record includes 78 PFAS sampling or contamination sites, 746 historic mine features, and 65 EPA Superfund or cleanup sites. Those locations do not automatically mean a particular well is contaminated. Test the actual water and check the site's proximity to mines, cleanup areas, septic systems, and drainage. Confirm casing, grout, wellhead protection, septic setbacks, access, and the building site's legal water use before committing.

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 (425 ft) would run roughly $33,625–$54,500. 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 Crisman 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 permitted well depth within five miles of Crisman is 285 feet. The middle half runs from 155 to 425 feet, while 12% of wells are 600 feet or deeper. The deepest record is 1,402 feet. Fractured granite and gneiss make depth unpredictable, so nearby well records are useful when planning a bid.
The local drilling model is $65-$100 per foot. At the 285-foot median depth, the drilled hole is estimated at $18,500-$28,500. A finished well with pump, tank, trenching, and electrical work is estimated at $24,500-$40,500. A contractor should confirm access, casing, grout, testing, and possible extra-depth charges.
Reported well yield has a 7.0-gallon-per-minute median, with the middle half between 5.0 and 10.0 gallons per minute. Three percent of reported wells are under 1 gallon per minute. Ask for the actual pumping test and plan storage carefully, because a tested yield is not the same as unrestricted household consumption.
The permit records do not establish that every Crisman well is safe to drink. Nearby mapped environmental records include 78 PFAS sampling or contamination sites, 746 historic mine features, and 65 EPA Superfund or cleanup sites. Test the individual well for relevant contaminants, review its history, and maintain treatment based on the results.
Reported static water levels vary by measurement decade: 30 feet in the 1960s, 40 feet in the 1970s, 68 feet in the 1980s, 6 feet in the 2000s, 90 feet in the 2010s, and 100 feet in the 2020s. Only 125 wells report levels, so this is not proof of a uniform decline. Check nearby, comparable wells.
