Granada, Colorado Well Depths, Yields, and Costs

How deep are wells around Granada?

How much water do wells make near Granada?

Granada well depths depend on the local formation

Within five miles of Granada, 77% of recorded wells are under 100 feet. The middle half runs from 46 to 89 feet, which gives a driller a reasonable starting range for a shallow plains-sediment bid. That range is not a promise. The records also include wells from 300 to 600 feet, wells deeper than 600 feet, and a deepest record of 950 feet.

Most permits name an unnamed or fractured-bedrock aquifer. A smaller number identify the Cheyenne Sandstone or Dakota aquifers, and no recorded wells identify a Denver Basin aquifer. Ask for a written bid that explains what happens if the hole must continue past the expected formation or needs additional casing and grout.

Recorded yields are high, but the sample is small

The reported yield median near Granada is 113 gallons per minute, with a middle half from 22.5 to 1,225 gallons per minute. Of the wells that report a yield, 86% produce more than 15 gallons per minute, while 5% fall in the one-to-five gallon range and none are recorded under one gallon per minute.

Those results are encouraging for irrigation and stock uses, but only 22 wells report a pump yield. A domestic buyer should not size a house system from the local median alone. Confirm the permit’s allowed use, test the well, and ask whether the pumping rate is a short test result or a dependable operating rate. Exempt household-use wells still have Colorado pumping limits and use restrictions.

Water levels vary widely in Granada records

Only 11 wells in the records report a static water level. Their median depth to water is 190 feet, with the middle half ranging from 23 to 287 feet. That spread shows why a nearby well’s water level may not predict the level at a particular lot, especially where well depths and named formations differ.

The permit counts by decade do not establish a groundwater trend. They show activity from the 1950s through the 2020s, with the newest permit issued in 2025, but they are not a time series of static water measurements. For a purchase, obtain the well construction report, static level, pumping information, and any available nearby measurements rather than assuming the water table is rising or dropping.

Permit history points to long local drilling experience

Granada’s permit record contains 258 wells, with 172 recorded as constructed and 174 reporting a total depth. The permits cover household, stock, irrigation, and monitoring uses. Irrigation accounts for 60% of the listed use mix, followed by stock at 15% and domestic or household use at 12%.

The most active names in these records are Ark Valley Pump & Supply, associated with Smith Jr., William, with 20 wells; Hoffman, associated with Hoffman, Earl, with 11; and Authorized, associated with Pe, Pg, with 9. These records can help identify local experience, but they do not rank current workmanship. Check licensing, references, the proposed construction method, and who will service the pump after completion.

A shallow Granada well may still cost more than expected

For Granada’s alluvium and plains sedimentary rock, the drilling model uses $35 to $55 per foot. At the local median depth of 64 feet, the drilled hole models to about $2,200 to $3,500. That is only the hole. A finished system with pump, pressure tank, trenching, and electrical is modeled at about $8,200 to $15,500.

Get the driller to separate drilling, casing, grout, development, pump equipment, electrical work, trenching, testing, and permit-related work. A deep outlier, difficult access, extra casing, or a change in formation can move the price above the shallow-hole estimate. The middle-half depth range of 46 to 89 feet is useful for comparison shopping, not a fixed bid.

Check contamination, septic layout, and dry-hole exposure

Mapped environmental information within about 10 miles includes 3 PFAS sampling or contamination sites, 1 historic mine feature, and 4 EPA Superfund or cleanup sites. That does not prove a parcel’s water is unsafe, but it is enough reason to test before relying on the well. Review the well location, casing and grout, nearby land uses, and any available laboratory results.

Low yield is not the only concern. A dry hole, poor construction, pump failure, or unsuitable water quality can affect a building budget. Confirm that the proposed septic field, replacement area, driveway, and house site can fit with the well and required separation distances. In an over-appropriated basin, ask the Colorado Division of Water Resources about augmentation and the permitted use before planning additional domestic, irrigation, or livestock demands.

What to verify before buying near Granada

Start with the parcel’s permit number and construction report, then compare nearby wells in Granada, Hartman, Holly, Lamar, Wiley, Brandon, and Sheridan Lake where records are relevant. Pay closest attention to wells with the same intended use and similar depth or aquifer. A high reported yield in an irrigation record does not automatically establish a reliable household supply.

Before closing, confirm the permit status, legal use, well location, production test, static water level, water-quality test, and pump condition. If the lot has no well, obtain a site-specific drilling estimate and ask what happens if the first target is unproductive. For a new build, coordinate well, septic, electrical, access, and house placement before excavation. That sequence can prevent a workable lot from becoming an expensive redesign.

What a new well costs in Granada, 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 (89 ft) would run roughly $9,115–$16,895. 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 Granada? 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 Granada 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.
