Do you need to check water rights before buying land in Custer County, Colorado?
Yes. In Colorado, water is not automatically included with land — it’s a separate, legally distinct property right governed by the prior appropriation system. Before you make an offer on land, a cabin, or a ranch in Custer County, you need to know exactly what water source serves the property, whether that source is a permitted well or a decreed water right, and whether it’s actually being conveyed to you in the sale. Skipping this step is one of the most common — and most expensive — mistakes rural buyers make in the Wet Mountain Valley.

Most buyers moving toward Westcliffe from a city or suburb have never had to think about water as anything other than a utility bill. Out here, it’s different. Water in Colorado is treated as real property — something that can be bought, sold, leased, or severed from the land entirely, separate from the dirt itself.
That distinction catches people off guard constantly, and it’s one of the questions I field most from buyers looking at land, cabins, and horse properties across Custer County.
Water in Colorado Isn’t Automatically Part of the Land
Colorado follows the prior appropriation doctrine — “first in time, first in right.” The person or property that put water to beneficial use earliest holds the senior, most protected claim to it. Everyone who came later holds a junior right, which means in a dry year, senior rights get satisfied first and junior rights can be curtailed.
For a buyer, that means two properties that look identical on paper — same acreage, same well house, same irrigated pasture — can have completely different water pictures depending on the priority date attached to the right.
Here’s what actually determines that picture:
- Priority date — when the water right was first put to use, which determines how protected it is in a shortage
- Type of right — a permitted well, a decreed surface right, or shares in a ditch or reservoir company
- What’s actually being conveyed — water rights can be sold separately from the land they’ve historically served, so owning the property doesn’t guarantee you own the water
The Three Types of Water Rights You’ll Run Into Here
Almost every property you look at in Custer County will fall into one, or a combination, of these categories:
- A permitted well. Most rural homes rely on a groundwater well permitted through the Colorado Division of Water Resources. Many are covered under the state’s “domestic well” exemption, which allows limited household use without a fully adjudicated water right — but that exemption comes with pumping and use limits, and it’s a junior right that can be curtailed in a real shortage.
- A decreed water right. Larger or agricultural properties may have a right that’s gone through Colorado’s water court system, which formally establishes the amount of water and its priority date. These are treated much like a deed to land and can be described directly in your purchase contract.
- Ditch or reservoir shares. Some ranch and irrigated land in this area draws water through a mutual ditch or reservoir company. Ownership here works more like owning stock — the shares are what get assigned and transferred, not the water itself.
Whichever type you’re dealing with, the same rule applies: get the exact right identified, confirm the seller actually holds clear title to it, and make sure it’s properly conveyed at closing — not assumed to come with the property.
What This Means When You’re Writing an Offer
This is where it becomes a practical, not just legal, question. A property with a solid, senior water right is worth more than an identical property with a marginal or unclear one — and that difference should show up in how you negotiate.
Before you get too far into a deal on land, a cabin, or a ranch out here, work through this:
- Ask the seller directly what type of water right serves the property and request supporting documentation — well permit, decree, or share certificate
- Confirm whether the water right will be conveyed with the land in the Seller’s Property Disclosure and purchase contract, since it isn’t automatic
- Have a well tested for yield and water quality before you remove contingencies, not after
- If the property relies on a decreed right or ditch shares, loop in a water attorney or hydrogeologist — this is not a step to handle solo
Your specific situation — whether you’re buying five acres for a cabin or 80 acres for horses — changes how much due diligence this really requires. That’s exactly the kind of conversation worth having with someone who knows this market before you write an offer.
Sellers: Know What You’re Actually Selling
If you’re on the other side of this — selling land, a ranch, or an in-town home with a well — the same rules apply to you. Colorado’s Seller’s Property Disclosure requires you to be upfront about the water source and any known issues with it.
Buyers in this market are asking sharper questions about water than they used to, and a property with clean, well-documented water rights typically moves faster and negotiates better than one where the paperwork is thin or missing. If you’re not sure what you actually hold, that’s worth sorting out before you list, not after an offer comes in and a title company flags a gap.
Frequently Asked Questions
Does buying land in Custer County automatically include the water rights?
Not necessarily. Water rights in Colorado are treated as a separate property interest and can be sold, leased, or held back by a previous owner. Always confirm in writing what’s included in your specific transaction.
What’s the difference between a well permit and a decreed water right?
A well permit, issued by the Colorado Division of Water Resources, authorizes groundwater use — often under a limited domestic exemption for household needs. A decreed water right has gone through Colorado’s water court and carries a formal priority date, giving it stronger legal protection in a shortage.
Do I need a water attorney to buy property with a well in Custer County?
For a straightforward domestic well on a small parcel, your real estate agent and title company can often confirm what you need. For larger acreage, ranch land, or decreed rights and ditch shares, a water attorney or hydrogeologist is worth the cost before you close.
Who handles well ownership transfer in Colorado?
Colorado requires the buyer to file a Change in Owner form with the state at or shortly after closing for wells, separate from the standard deed transfer for the land itself.
Can a domestic well run out of water during a drought?
Yes. Most rural domestic wells operate under a junior right, meaning that in a serious shortage, senior rights are satisfied first. It’s one of the reasons well testing and documentation matter before you buy.
