What Florence, Colorado Well Records Tell You

How deep are wells around Florence?

How much water do wells make near Florence?

Florence well depth depends on the ground beneath the lot

Recorded wells near Florence have a median depth of 55 feet. The middle half runs from 32 to 180 feet, which gives a driller a useful local range but not a promised target. Sixty-one percent of recorded wells are under 100 feet, while 19% fall between 100 and 300 feet. Another 11% are 300 to 600 feet, and 9% exceed 600 feet.

The spread reflects mountain ground identified on permits mainly as unnamed or fractured-bedrock aquifer. Granite and gneiss can change quickly across a property, with water-bearing fractures appearing at different depths. For a bid, ask the driller to price the expected hole depth separately from casing, grout, pump, and other completion work. A 55-foot median is useful for budgeting, but it should not be treated as a drilling limit.

Expected well yield around Florence

Among the Florence-area records that report pump yield, the median is 10.0 gallons per minute, with the middle half between 5.0 and 15.0 gallons per minute. Half of reported wells fall in the 5-to-15-gpm range, and 31% report more than 15 gpm. Eighteen percent report between 1 and 5 gpm, while 2% are under 1 gpm.

Only 124 wells report a pump yield, so the percentages describe reported tests rather than every permitted well. For a buyer, the main concern is dependable household supply during peak use, not just a strong short test. Request the well construction report, pumping test, storage details, and any production history. A low-yield well can sometimes work with storage, but that adds equipment and operating considerations.

Water levels and the record over time

Only 22 Florence-area records report a static water level, so the water-level sample is limited. In those records, the median depth to water is 22 feet, with the middle half from 20 to 29 feet. That suggests relatively shallow measured water levels in the reported wells, but it does not establish the water level for every parcel or prove a basin-wide trend.

Permit activity increased from 8 permits in the 1950s to 174 in the 2000s, then shows 111 in the 2010s and 40 in the 2020s. Those are permit counts, not water-level measurements, so they should not be read as evidence that the water table is dropping. Have the driller check nearby completed wells and ask how the proposed location compares with recent construction.

Who has drilled near Florence, and when

The permit history reaches back to the 1950s, with the newest permit year listed as 2025. The records show 783 permitted wells within 5 miles, 452 recorded as constructed, 509 with a total depth, and 124 with a pump yield. That is enough local history to compare nearby construction, but not every permit contains complete completion information.

The most active named drillers in the records are Finney Drilling, listed as Finney, Larry D., with 74 records; Authorized, listed as Pe, Pg, with 71; and Arkansas Valley Drilling, listed as Moore, Todd A., with 69. Treat those counts as permit-record history, not endorsements or proof that a company is currently available. Ask for current licensing, insurance, references, and a written scope before choosing a driller.

What a new Florence well may cost

Local ground is modeled as fractured mountain bedrock, including granite and gneiss. The drilling rate used for this area is $65 to $100 per foot. At the 55-foot median depth, the drilled hole works out to about $3,600 to $5,500. That is the hole only, not the complete water system.

A finished well with pump, tank, trenching, and electrical is modeled at about $9,600 to $17,500 at the median depth. A deeper hole can move well beyond that range, and a fractured-rock site may need additional work if the first interval does not produce enough water. Get the assumed depth, casing and grout, pump size, trench length, electrical work, testing, and permit-related tasks written into the bid so estimates can be compared fairly.

Risks to check before building near Florence

Water quality deserves a separate review from well quantity. Within about 10 miles, mapped environmental information includes 32 PFAS sampling or contamination sites, 62 historic mine features, and 5 EPA Superfund or cleanup sites. Those locations do not automatically mean a particular well is contaminated, but they are a reason to check the parcel, nearby land uses, and available agency records.

Low yield, dry holes, and fractured-rock variability are the practical drilling risks. Septic setbacks, replacement-area requirements, driveway access, and building placement also need to be checked before selecting a well location. A domestic permit does not eliminate the need to verify what the permit allows. Have water tested after construction and again when a property history or nearby environmental feature warrants it.

A sensible Florence lot-buying plan

Before closing, pull the permits for the property and compare them with nearby wells in Florence, Rockvale, Williamsburg, and Brookside. Look for completed depth, yield, static water level, casing information, and the actual use listed on the permit. The local use mix is 68% domestic or household, 17% stock, 4% irrigation, and 19% monitoring, so not every nearby well is a good comparison for a residence.

For a vacant lot, make the well location, septic area, access route, and electrical path part of the feasibility review. Have a licensed driller inspect the geology and price a realistic depth range instead of relying only on the 55-foot median. If the parcel depends on an exempt household-use well, confirm the current permit conditions and allowed uses with Colorado DWR before designing the home.

Well permits by decade near Florence

What a new well costs in Florence, CO

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 (180 ft) would run roughly $17,700–$30,000. See the full Colorado well cost guide.

Environmental sites mapped within about 10 miles

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.

Buying land near Florence? Know what it costs to build before you buy the dirt.

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

• Instant Online Report, $99 — type the address and get a buildability read on the spot: parcel, terrain and slope, soil and septic outlook. Cheap enough to run on every lot you're shopping.
• Desktop Report, $500 — a contractor's from-the-desk feasibility read: Regulation 43 and county code, GIS parcel data, terrain, flood and drainage, soil and septic viability, setbacks and buildable envelope, nearby well depths from our 591,000-well database, the likely driveway route, and a preliminary site-development cost breakdown.
• On-Site Report, $2,000 — everything above, then boots and a drone on the actual ground: house pad and septic zone located, access and winter conditions checked, rock and soil observed in person, a 15 to 20 page written opinion you can hand a lender or seller. Credited toward your project if you build with us.

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.
