Colorado Well Finder › Wells by county › Jefferson County › Brook Forest
In Brook Forest, finding water means finding productive fractures in mountain bedrock. Nearby wells provide a useful starting budget, but they cannot promise the depth or production on your lot.
Colorado DWR records include 7,113 permitted wells within 5 miles of Brook Forest, with 4,972 recorded as constructed. That neighborhood-scale picture includes the direction of Upper Bear Creek and Evergreen; it is not a count limited to Brook Forest itself. Start with these numbers, then narrow the search to wells closest to the property.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Brook Forest. Not every permit reports every field; each statistic uses the wells that report it.

The median reported well depth is 300 feet, based on 5,026 depth records. The middle half runs from 183 to 452 feet. For a buyer, that means a bid built around the median needs room for substantially more drilling—not just a small adjustment.
At the deeper end, the 90th-percentile depth is 604 feet, and the deepest recorded well reaches 1,502 feet. Most permits leave the aquifer unnamed or identify fractured bedrock; others specifically name crystalline rock or granite. Water comes from connected fractures rather than a predictable layer. A successful well next door is useful evidence, not a guarantee that your driller will hit water at the same depth.
Reported pump yields have a 5.0 gpm median, with the middle half between 3.0 and 8.5 gpm. Those figures come from 2,451 records, not every permitted well. A permit yield is a reported test result, not proof that an older well still produces that amount reliably.
The records put 3% of reported yields below 1 gpm. That is a meaningful buying risk: a low-producing well may need storage and careful demand management. Another 53% report 5–15 gpm. For an existing Brook Forest home, ask for a current production and recovery test, along with the pump and storage details. Strong pressure at a faucet does not establish sustained well production.
Static water level is the depth to standing water in a resting well—not the drilled depth. Among 207 reporting wells, the median is 70 feet below ground, with the middle half at 35–120 feet. That is a much smaller reporting group than the depth dataset.
Decade medians are 55 feet in the 1960s, 45 in the 1970s, 36 in the 1980s, 114 in the 2010s and 65 in the 2020s. These values do not show a steady dropping water table. They also are not repeated measurements of the same wells. Use them as background; the property's resting level, pumping drawdown and recovery matter more for a purchase.
The largest listed permit decade is the 1970s, with 2,006 permits, followed by 1,432 in the 1990s and 1,117 in the 1980s. The 2020s account for 145 permits, and the newest permit year is 2025. These are permit issuances, not a tally of wells completed in those periods.
Domestic and household uses make up 97% of the use mix. The most active driller entries are James Drilling Company (Keaton, Michael K.), with 656 records; Walton, with 649; and Ernie's Mountain Drilling Inc. (Malovich, Ernest J), with 482. Historical activity can help you trace construction records, but it does not establish who is currently available to drill.
The local cost model uses $65–$100 per foot for fractured granite and gneiss. At the 300-foot median depth, that puts the drilled hole at about $19,500–$30,000. A finished well with pump, tank, trenching and electrical is modeled at $25,500–$42,000.
Treat that as a planning range, not a parcel-specific quote. The 183–452-foot middle depth range leaves considerable room for the drilling total to move. Mountain access, equipment setup, casing and grout requirements, and the route to the house also affect the scope. Ask bidders to identify included work, depth allowances and how additional drilling will be authorized before the rig arrives.
Within about 10 miles, the mapped inventory includes 17 PFAS sampling or contamination sites, 38 historic mine features and 50 EPA Superfund or cleanup sites. Those counts flag reasons to investigate; they do not establish contamination in a particular Brook Forest well. A sampling location is not necessarily a confirmed contamination source.
Get laboratory testing and seek guidance on additional analytes based on nearby site records. Separately, have the well's production, casing, cap and surface drainage evaluated. Fractured bedrock can produce weak wells or unsuccessful holes, but these records do not establish a dry-hole rate. Review septic condition and placement too, especially where a proposed home, replacement system or driveway limits usable space.
Start with the parcel's DWR permit, well construction report and available pump-test records. Confirm that the permit's allowed uses match your plans; a household-use permit should not be assumed to cover outdoor watering or livestock. Existing plumbing does not establish legal water use.
Compare nearby wells around Brook Forest and toward Upper Bear Creek, then use Evergreen, Conifer or Upper Witter Gulch as broader context rather than substitutes for immediate neighbors. For vacant land, coordinate the well location with septic approval, building placement, rig access and utility trenching before finalizing the site plan. For an existing home, make current water-quality and production testing part of the purchase investigation.

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 (452 ft) would run roughly $35,380–$57,200. 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.
The numbers above are the area average. Your lot is one point on the map. Search the address to see the real depth, yield and aquifer of each permitted well around it.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Brook Forest 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.

Within 5 miles of Brook Forest, the median reported well depth is 300 feet, and the middle half runs from 183 to 452 feet. Fractured mountain bedrock makes depth difficult to predict lot by lot. Use nearby construction reports to set a drilling allowance, rather than assuming your well will stop at the median.
The drilling model is $65–$100 per foot in fractured mountain bedrock. At the 300-foot median depth, the hole alone is about $19,500–$30,000. A finished well with pump, tank, trenching and electrical is about $25,500–$42,000. Get a site-specific bid that addresses access, casing and charges for drilling beyond the planned depth.
The median reported pump yield is 5.0 gpm, with the middle half at 3.0–8.5 gpm. Among reported yields, 3% are below 1 gpm. An existing home's current production and recovery test is more useful than its original permit yield, particularly when evaluating storage needs and whether supply fits household demand.
Safety cannot be determined from a permit or neighborhood averages. The surrounding mapped inventory includes 17 PFAS sampling or contamination sites and 38 historic mine features within about 10 miles, but proximity does not prove your well is affected. Test the property's water and use nearby environmental records to guide any additional laboratory testing.
The available decade medians do not show a steady decline. Median depth to water was 36 feet in the 1980s, 114 feet in the 2010s and 65 feet in the 2020s. Only 207 wells report static levels, and the series does not track the same wells repeatedly. Check the property's own measurement history and pumping recovery.
