Here's the short version: in Colorado, owning the land does not mean you own the water. Water rights are a separate legal property interest under the state's prior appropriation system ("first in time, first in right") (Colorado Division of Water Resources, Water Rights). On top of that, many wells on parcels under 35 acres are permitted for household use only, which means you can't legally water horses with them, and much of Douglas and Elbert County sits over the Denver Basin aquifers, which come with their own rules (DWR, Denver Basin).
Before you fall in love with a barn and a pasture, run through these questions:
- What kind of well permit does the property actually have (household-use-only, domestic exempt, or a decreed non-exempt well)?
- Is the parcel 35 acres or more, or under 35 acres?
- Does the permit allow livestock watering and irrigation, or just indoor use?
- Which Denver Basin aquifer does the well tap, and is the lot in a subdivision whose wells run under a court-approved augmentation plan?
- Have you pulled the permit file from the Colorado Division of Water Resources?
- Does the zoning even allow the number of horses you want to keep?
Let's walk through each one.
Why does owning the land not mean owning the water?
This trips up almost every buyer coming out to acreage for the first time. You'd assume that if you buy the dirt, the water underneath comes with it. In Colorado, that's not how it works.
Water here is a public resource, and the right to use it is a separate, transferable property interest that doesn't always convey with the deed. The whole system runs on prior appropriation: older, court-decreed rights (senior rights) get to use water before newer ones (junior rights) when supply runs short (Colorado Division of Water Resources, Water Rights).
I've had buyers assume the seller's irrigation or livestock water came with the house. Sometimes it does. Sometimes it absolutely does not. You have to verify it, not assume it.
What does a "household-use only" well permit actually let you do?
It covers ordinary household use inside one single-family home. No watering horses. No irrigating pasture. No filling a stock tank. Nothing outside (Colorado Division of Water Resources, Beginner's Guide to Well Permits).
So you could buy a lovely little 5-acre place with a barn, and legally speaking that well can't put a drop into your horse trough. I've seen people find this out after closing, and it's a rough conversation. Ask about it up front.
What's the deal with the 35-acre rule?
The 35-acre line is one of the most important numbers for horse buyers in Douglas and Elbert County, because it changes what a well can legally do. Under the Colorado Division of Water Resources' Beginner's Guide to Well Permits, a "household use only" exempt permit covers ordinary household use inside one single-family home, with no outdoor watering and no livestock, while a "domestic" exempt permit can serve up to three single-family homes, irrigate up to one acre of lawn and garden, and water domestic animals and livestock (DWR Well Permitting).
35 acres or more
DWR says domestic uses are generally available on a parcel of 35 acres or more that isn't in a court-approved augmentation plan or a subdivision created after June 1, 1972, when the well is the only exempt well on that 35-acre-or-larger portion (DWR Well Permitting).
Under 35 acres
Smaller parcels aren't automatically limited to household use. DWR says domestic uses can also be available on parcels in the Denver Basin or a Designated Basin, while lots in subdivisions created after June 1, 1972 usually get their well uses from the subdivision's augmentation plan (DWR Well Permitting). One date confuses people: May 8, 1972 is the cutoff DWR uses for registering a residential or livestock well that was already in use before then. It isn't the subdivision date. The permit itself is the final word, so read it.
How do the Denver Basin rules affect wells in Douglas and Elbert County?
The Denver Basin runs along the Front Range from Greeley to Colorado Springs and from the Foothills east to Limon. It's a stack of bedrock aquifers (the Dawson, Denver, Arapahoe and Laramie-Fox Hills) that DWR describes as nonrenewable: when the water is pumped, it's "mined," not replaced (DWR, Denver Basin).
Because of that, Colorado limits how much a landowner can take. Under C.R.S. 37-90-137(4), enacted in 1973, a landowner may withdraw only the water determined to be underlying their land, and withdrawals are based on a 100-year aquifer life, which works out to an average of 1% of that water per year. DWR uses the same premise to set the uses allowed on many exempt on-lot wells that tap Denver Basin water (DWR, Denver Basin). In practice, two neighboring parcels can carry very different permits depending on lot size, which aquifer the well taps, and when and how the lot was created.
What is an augmentation plan, and will I need one?
An augmentation plan is a water court-approved plan that protects existing water rights by replacing the water a new use consumes (DWR Beginner's Guide to Well Permits). Horse buyers run into it in two ways. First, most lots in subdivisions created after June 1, 1972 get their well uses from a subdivision-wide augmentation plan, and DWR says uses beyond what that plan allows have to be added through water court, if that's possible at all. Second, a non-exempt well pumping not-nontributary Denver Basin water outside the Designated Basins needs a court-adjudicated augmentation plan under C.R.S. 37-90-137(9)(c.5) (DWR Beginner's Guide to Well Permits).
If you're buying a smaller parcel and want to legally water horses beyond what its permit allows, ask whether the subdivision has an augmentation plan and what it covers. Changing one is not cheap or instant, so build the time and cost into your plan before you write an offer. This is exactly the kind of thing I dig into with buyers at The Seville Team before we get too far down the road.
How do I actually check a well permit during due diligence?
Don't take the listing description's word for it, and don't take mine either. Go to the source.
The Colorado Division of Water Resources (DWR) administers every well permit in the state, monitors aquifer levels, and maintains a public Well Permit Search Tool. The permit file will spell out what that specific well is allowed to do. Pull it during your inspection period, not after closing.
Here's the practical checklist I run with equestrian buyers:
- Look up the permit number in the DWR Well Permit Search Tool and read the allowed uses.
- Confirm whether the parcel is over or under 35 acres.
- Ask whether the lot is in a subdivision created after June 1, 1972 and, if so, what its augmentation plan allows.
- Ask the seller for any augmentation plan documents or water shares.
- Verify the permitted production rate if you're counting on it for livestock.
- Have a Colorado water attorney review anything that isn't crystal clear.
Water law is one of the few areas where I genuinely tell people to bring in a specialist. It's worth the fee.
What does Elbert County zoning allow for horses?
Water is only half the equation. You also need the zoning to allow the horses themselves.
In Elbert County, Article XIV of the Zoning Regulations allows one animal unit per half acre (one horse is one unit) in the RA, RA-1, RA-2, AR and A-2 zones and on nonconforming parcels under 35 acres. The R-1 zone allows two horses, and the R-2 zone allows none (Elbert County Zoning Regulations, Article XIV.C).
So on a 5-acre lot, the density math allows up to ten horses on paper, but your water permit might not support any of them outside the house. Zoning and water rights are two separate green lights, and you need both. Douglas County and El Paso County have their own rules (Douglas County's are in Section 24 of its Zoning Resolution), so check the specific county your property sits in.
A grounded piece of advice
I've lived in Elbert County for 22 years and raised my kids here, and I've watched buyers do this the easy way and the hard way. The easy way is asking the water questions before you're emotionally attached to the property.
Horse property is different from a subdivision home. The barn matters. The pasture matters. But the paperwork behind the water matters just as much, and it's a lot harder to fix after you own it.
If you're thinking about a place in Elizabeth, Franktown, Kiowa, Parker, Castle Rock, or anywhere out in Douglas or Elbert County, give me a call and I'll help you pull the well permit and check the zoning before you write an offer.
