Colorado Well Finder › Wells by county › Larimer County › Estes Park
Buying land or a home around Estes Park means dealing with mountain bedrock, variable well depths, and uneven groundwater information. Within 5 miles of Estes Park, Colorado DWR records include 1,728 permitted wells. Of those, 1,169 are recorded as constructed, 1,157 report total depth, and 533 report pump yield.
The local record points to a typical well around 260 feet deep with a 5.0 gpm reported median yield. That is useful for planning, but it is not a guarantee for a specific lot. Fractured granite and gneiss can produce water through isolated fractures, so neighboring wells and a site-specific drilling bid matter more than a countywide average.
Figures are computed from Colorado Division of Water Resources permit records for permitted wells within 5 miles of Estes Park. Not every permit reports every field; each statistic uses the wells that report it.

The median reported well depth near Estes Park is 260 feet. The middle half runs from 140 to 405 feet, so a driller pricing an ordinary site should not assume every well will be close to the median. Ten percent of the reported depth mix is 600 feet or deeper, and the deepest recorded well reaches 1,201 feet.
The depth mix is spread across the range: 17% are under 100 feet, 38% fall between 100 and 300 feet, 34% between 300 and 600 feet, and 10% are 600 feet or deeper. In this mountain setting, most permits name an unnamed or fractured-bedrock aquifer. That fractured granite and gneiss can make two nearby parcels perform very differently.
Among the 533 wells with a reported pump yield, the median is 5.0 gpm and the middle half is 4.0 to 7.0 gpm. The local results are concentrated in the 5-to-15-gpm range, which accounts for 66% of reported yields. Another 20% produce 1 to 5 gpm, 8% produce more than 15 gpm, and 6% are under 1 gpm.
For a buyer, the under-1-gpm share is the warning number. A low-yield well may still serve a household with adequate storage and careful use, but it leaves less margin for guests, irrigation, or a larger home. Ask for the well construction report, pump test information, and any seller records rather than relying on a listing description.
Reported static water level has a median depth of 66 feet below the surface, with the middle half from 24 to 100 feet. Only 86 wells report a static water level, so this is a limited sample rather than a complete groundwater survey.
The decade figures do show a deeper reported water level than in the earlier records: the median was 30 feet below surface in the 1960s, compared with 100 feet in both the 2010s and 2020s. That pattern is consistent with a lower measured water table in the later records, but the available measurements are sparse and may reflect different locations, seasons, and measurement practices. Have a driller or qualified water professional evaluate the specific parcel.
Permit history is useful when checking neighboring wells, although it does not predict the result on your lot. The most active names in these records are Ingram Drilling Inc. (Ingram, Stephen E.) with 569 permits, Young, Ernest C with 238, and Ground Water Systems Inc (Wilson, Richard R.) with 76.
Permits span the 1950s through the newest permit year, 2025. The largest decade totals are 326 permits in the 1990s, 315 in the 1980s, and 295 in the 1970s. The records also show 86% domestic or household use, with smaller shares for stock, irrigation, and monitoring. Check current Colorado DWR permits and construction reports for the parcel and nearby properties in Glen Haven, Allenspark, Drake, and other surrounding areas.
Here, the cost model assumes fractured mountain bedrock, including granite and gneiss. The drilling rate is typically $65 to $100 per foot. At the local median depth of 260 feet, the drilled hole works out to about $16,900 to $26,000.
A usable water system costs more than the hole. The estimated finished-well range, including pump, pressure tank, trenching, and electrical, is about $22,900 to $38,000 at that median depth. A deeper hole, difficult access, casing and grout requirements, or extra site work can move the final price higher. Use the 140-to-405-foot middle-half depth range when comparing bids, and make sure each bid states what is included.
Low yield and dry-hole risk deserve attention in fractured mountain rock because water may be concentrated in separate fractures. The records show 6% of reported yields under 1 gpm, while only 533 wells report a pump yield. That missing information is itself a reason to request original well reports, pump tests, and production history.
Environmental screening also matters. Mapped sites within about 10 miles include 9 PFAS sampling or contamination sites, 3 historic mine features, and 1 EPA Superfund or cleanup site. These locations do not prove contamination at a particular home, but they justify testing the well water and checking the site history. Confirm septic setbacks, soil conditions, driveway access, and the proposed building envelope before closing. A household-use well permit and an augmentation plan can have different implications, especially in a regulated or over-appropriated basin.
Start with the well permit, construction report, pump details, static water level, and any water-quality tests. Compare the property with nearby wells instead of treating the 260-foot median or 5.0-gpm median as a promise. Ask how the existing well performs during dry periods and whether the pump, tank, trench, and electrical equipment are nearing replacement.
For raw land, confirm access for a drilling rig and excavation equipment before choosing a house site. Have the septic designer evaluate soils, setbacks, and the relationship between the well and septic system. Colorado DWR records are a necessary starting point, but a driller should inspect the parcel and explain the risk of going deeper. Also verify the proposed use: an exempt household-use well has limits, including the 35-gpm exempt-well pumping limit, and larger or different uses may require additional water-right planning.

A listing photo can't tell you whether a lot is a dream or a money pit. Two parcels near Estes Park 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 Estes Park is 260 feet. The middle half runs from 140 to 405 feet, while 10% of the depth mix is 600 feet or deeper. The deepest record reaches 1,201 feet. Because most permits name fractured-bedrock aquifers, depth can vary substantially between nearby mountain properties.
The local drilling model uses $65 to $100 per foot in fractured granite and gneiss. At the 260-foot median depth, the drilled hole is estimated at $16,900 to $26,000. A finished well with pump, tank, trenching, and electrical is estimated at $22,900 to $38,000. Access and extra construction needs can change the bid.
The median reported pump yield is 5.0 gpm, with the middle half between 4.0 and 7.0 gpm. About 66% of reported yields fall between 5 and 15 gpm. However, 6% are under 1 gpm, and only 533 wells report a yield, so a neighboring well cannot guarantee production on your parcel.
The permit records do not establish that a particular well is safe to drink. Mapped sites within about 10 miles include 9 PFAS sampling or contamination sites, 3 historic mine features, and 1 EPA Superfund or cleanup site. Test the well water before relying on it, and review the parcel and nearby site history with a qualified professional.
The reported median static water level was 30 feet below surface in the 1960s and 100 feet in both the 2010s and 2020s. That suggests deeper measured water levels in later records, but only 86 wells report static water levels. Different locations, seasons, and measurement methods limit how confidently the series describes a regional trend.
