One surveyed section, about a square mile CO060060S0890W0SN270
This report describes a surveyed section: 640 acres, one square mile. This one is cut into 389 separate parcels. Every number below that says “in this section” is counted across all of it: the wells, the water rights, the filings and the records behind them. So a count of wells is not a count of wells on your ground, and a right of record in this section is not necessarily a right that comes with it. That is the useful scope rather than a limitation: what your neighbours drilled, how deep they had to go and what they hit is the best available guide to what this ground will do. Read it as the context it is. What conveys with a particular parcel is settled by the deed and the well permit for that parcel, and this report says which documents to ask for.
This is a 2.1-acre parcel in Garfield County. The square mile around it holds 38 water rights of record and 68 well permits. Of those, 37 of the rights are still live (1 sits on structures the state records as gone) and 36 of the permits are still a permission, the rest expired, were refused, or describe wells since abandoned. 18 of the rights irrigate at more than household scale, and 4 more water a lawn or garden. The most serious thing here is that rALSTON #1, upstream of this ground, is rated UNSATISFACTORY by the state. 3 other findings need a closer look. Every finding below links to the record it came from.

Check this is the property you mean. A point-in-polygon match against the assessor boundary is exact, but the coordinates came from the listing. If it published its ranch gate, this is the gate's parcel and every figure in this report describes the wrong square mile. Two scales appear below. This parcel, 2 acres, is the property. Everything counted “in this section” covers the surveyed square mile it sits in, about 640 acres, because that is the unit Colorado files water at. A well or a right in this section is somewhere in that square mile and usually not on this parcel.

Things a buyer has to resolve before closing.
RALSTON #1, upstream of this ground, is rated UNSATISFACTORY by the state #
In the record
Water released or escaping from a dam above this point arrives here. A decree says what may be stored; the dam decides whether it can be. The state's current restriction is "Continue Existing Restriction". Storage rights tied to this structure are worth what the reservoir may lawfully hold, which is not necessarily the decreed figure. The dam safety file is the State Engineer's own record and is the document to ask about before pricing the storage.
A dam rated unsafe is a repair bill attached to somebody, and the state can order the reservoir drawn down. Find out who owns it and what the order says before valuing any storage behind it.

The name on the water does not match the name on the land #
Our reading
DWR keeps a contact of record for every structure. It is who the state writes to about the headgate, which is frequently the operator, the ditch company, or an owner from two sales ago. It is not a record of who owns the right. The assessor bills HALLIWELL, PHILIP M & BROOKE M for this parcel, and no structure serving it lists that name. In Colorado a water right conveys separately from the land. This is the case where a buyer gets the ground and not the water. Ask for the instrument that conveys each right, by WDID or case number, and have it checked at the county clerk and recorder. We found no online index for Garfield County, which is not the same as there not being one. Colorado has no statewide index, so ask that county's clerk and recorder directly. One last thing to ask about separately: shares in a mutual ditch company. A great deal of Colorado irrigation water is held that way, and shares are personal property. They move by stock certificate, not by deed, so they show up in neither DWR's records nor the county grantor index.
Two different names is where a diligence problem usually first shows. Reconcile the deed, the well permit and the water right before assuming any of them convey together.

Nearly all of this section is wildland-urban interface #
In the record
Housing and wildland vegetation are mixed together across this ground, houses set among the trees and brush. Two things follow. Colorado carriers have been declining and non-renewing in the interface, so an insurance quote in writing belongs before contingencies come off rather than after. And a governing body with jurisdiction in the wildland-urban interface has to adopt the state minimum wildfire code, which sets ignition-resistant construction and defensible space requirements a new build or a substantial remodel has to meet. 22% of the section is interface that was not in 1990, so this is ground built into within living memory. Most of it was already interface by 1990. Whether the county has adopted the state wildfire code, and whether this ground falls inside the board's own map rather than this one, is a question for the county building department. Colorado publishes the code map as image tiles, so no report can read it.
Call an insurer before you are under contract. Whether a policy is written here at all is a yes-or-no question, and the answer decides whether the property is financeable.

17 of the 33 wells drilled here have no record of ever being used #
In the record
More than half the holes drilled on this ground carry no pump installation. That is not proof each one failed, since a pump can go in without the paperwork following, but it is the state's own record of what happened after permission was given, and it is worth asking about before you budget for a well.
A permit is permission to look. Ask for the completion report and the pump test for any well you are being told exists; without them the well is a hole of unknown value.

True of this ground, and not a problem by itself.
20 well permits here expired with no record of construction #
In the record
A permit is permission to drill and it runs out. These passed their expiry date and the state holds no completion report, no depth, no pump installation and no first beneficial use for them, so there is nothing on the record showing a well was ever built. That matters because the permission does not survive: drilling now means a new application under today's rules, and in a designated basin or a closed aquifer that application can be refused outright. A property described as having a well permit may be describing this. The most recent expired in 2021. The completion report is the document to ask for; if one exists, the state's file is simply behind.
An expired permit is not a well and it is not a right to drill one. Assume any water on this ground has to be permitted from scratch, on today's rules rather than the ones that applied when these were issued.

CRYSTAL RIVER was flowing 15.6 CFS on 7 September #
In the record
Read at CRYSTAL RIVER AT DOW FISH HATCHERY AB CARBONDALE on this reach, on the same stream as the water decreed here rather than the nearest gauge on a map. Read it as a snapshot and not as a season. A creek running well in the morning can be called out by the afternoon and dry by September. What it is good for is sanity-checking a listing against the river, and knowing whether the gauge that governs this reach is even reporting. 5 stations report on this reach or the water feeding it.
This is what is in the channel now rather than what is decreed. Useful for what you would see walking it this week; it says nothing about a dry August.

117 of 117 irrigated acres in this section are hay or pasture #
In the record
Hay and pasture are the lowest-consumption irrigated uses in Colorado, and that matters in two directions. They need less water an acre than row crops, so the same right stretches further. But historical consumptive use is measured on what was actually grown, so ground that has only ever raised grass supports a smaller transferable yield if the right is ever moved or changed. That is 100% of the irrigated ground mapped in this square mile.
If the plan is to grow something thirstier, get an engineer's read on the historical consumptive use before you buy. A change of use is quantified on what the ground actually grew, so a hay history caps what the right can be moved to.

None of the 38 rights here have a state curtailment analysis #
Not in the record
DWR runs a per-structure analysis of how often a right is actually called out, and it is the only authoritative answer to that question. We pull these from the state one structure at a time against a daily limit, and 38 have not been pulled yet. So nobody can yet say how often this water is actually called out. Any figure for it elsewhere here is our own screen against structure names, which raises the question rather than settling it. Our own name-matched screen reaches 24, and it overstates by a median of 94 days a year where it could be checked against the state's, so it raises a question rather than answering one.
Read the coverage before the conclusions. Where the state has analysed little, the quiet parts of this report are silence rather than good news.

33 water court cases decreed the structures here #
In the record
These are the decrees behind the rights on this ground, and the case number is what a water lawyer works from. The decree states the amount, the priority, the uses it was decreed for, and every condition the court attached. The summary records we build on carry none of that in full. Ask the seller for the decrees, or pull them from the water court for this division.
The decree is the document, not this summary. Pull the case and read what it actually permits, on what terms, and to whom.

1 structure here predates 22 May 1972 #
In the record
Colorado's groundwater administration changed on that date, and rights and wells in production before it are not always held to the limits quoted for a modern permit, a well pumping 50 gpm before 22 May 1971 can still be exempt where a new one would be capped at 15. It does not follow that any particular structure here enjoys that, which depends on continuous use and on what the decree says, but it is the reason to check rather than assume the current rule applies.
Structures this old often predate the paperwork that would describe them. Expect the record to be thin and the physical condition to matter more than the file.

The county appraises this parcel at $1,511,470 #
In the record
This is the assessor's figure. It is not a market estimate and it does not appraise the water. Colorado values agricultural land on what it can PRODUCE rather than what it would sell for, so on irrigated ground this number is usually far below a listing price and the gap is not evidence of anything. It is here because it is the county's own published position on the property, and because a water right's contribution to value is not in it at all. The assessed value it is taxed on is $106,560.
An assessor's figure is for taxation, not a market appraisal, and in most Colorado counties it lags a sale by a year or more. Use the comparable sales below instead.

None of this 2.1-acre parcel is mapped as irrigated #
In the record
Colorado's irrigated-lands mapping shows no irrigated ground inside this boundary. The mapping is a snapshot and its vintage differs by division, so this is evidence rather than proof, but a listing describing irrigated acreage should be reconciled with it. There ARE 117 irrigated acres mapped in this square mile, and none of them fall inside this parcel: the irrigated ground is elsewhere in the section.
Nothing on this parcel is mapped as irrigated even though the section is. Ask which part of the ground the water actually reaches before paying for irrigated acreage.

12 nearby land sales in the last five years #
In the record
The closest recorded sales of 35 acres or more in the last five years, from the county assessor roll, 2021 to 2025. The middle one worked out at $9,247 an acre. These are what the county recorded, not asking prices, and the roll lags a closing by months. Two bounds are deliberate: nothing under 35 acres, because a house on a fifth of an acre divides out to a per-acre figure about the house rather than the land, and nothing older than five years, because ground that changed hands a decade ago is a different market rather than a comparable. These are the closest that qualify, so where the nearest is some miles out that is what the record holds rather than an oversight. Distance, acreage and water differ between them, which is the point of showing each rather than an average: read the distance and the irrigated share beside the price. 2 of these 12 carry mapped irrigation.
These are the nearest thing to a price for this ground that the public record holds. They are not an appraisal and the parcels are not identical, so compare the distance, the acreage and the irrigated share before comparing the price.

119 live well permits nearby are for ordinary domestic use #
In the record
Colorado's exempt-well statute is unusually specific, and every limit in it is a number worth planning against. A well inside the exemption may not exceed fifteen gallons per minute of production, may not serve more than three single-family dwellings, and may be used for ordinary household purposes, fire protection, the watering of poultry, domestic animals and livestock on farms and ranches, and the irrigation of not over one acre of home gardens and lawns. That last one is the limit people meet first: a lawn and a garden are inside it and a pasture is not. 30 other live wells nearby carry a household-use-only condition instead, which grants less than this. A permit can always be narrower than the statute, so the entitlement above describes the exemption rather than any particular permit here. Read the permit itself before relying on any of it. The statute sets the ceiling and the permit can sit below it.
Count the dwellings the plan needs against the three the exemption allows. That limit, more often than the flow rate, is what stops a second home or a family compound on one parcel.

Soil here is rated VERY LIMITED for septic in places, but not everywhere #
In the record
USDA's published septic interpretation. It does not mean a system is impossible; it means a conventional leach field will not pass, and the buyer is looking at an engineered system, which runs to tens of thousands of dollars and is sometimes refused outright by the county. Ratings vary across this section and better ground is mapped inside it, so where the house goes decides which rating applies. Worth locating the building envelope on the soil map before removing contingencies. Slopes run 2 to 43%.
Where the building envelope sits decides the answer here. Get the perc test on the spot you intend to build on, not on the parcel generally.

FEMA has never mapped this area for flood #
Not in the record
No flood study exists here, which is common across rural Colorado. Nobody has looked, which is a different thing from someone looking and finding the risk is low. Ground that was mapped and came back outside the floodplain has an answer. This has none.
Unmapped is not the same as safe: it means FEMA has not studied it, so there is no elevation to build to and no rating to insure against. Ask the county what it requires here.

56 community water systems serve Garfield County #
In the record
About 50,685 people in Garfield County are on a community water system. 38 draw groundwater and 18 draw surface water. The federal compliance record holds 95 health-based violations across those systems, all returned to compliance, alongside 965 monitoring and reporting violations, which mean a late sample rather than bad water and are counted separately for that reason. This is a county-level count. The federal register records the county a system serves and Colorado publishes no service-area boundaries, so it says what exists in Garfield County, not whether any line reaches this parcel.
County-level context, not a supply for this parcel. It tells you whether a tap is even a concept here before you go looking for one.
EPA Safe Drinking Water Information System (SDWIS)
Soil here holds water at the surface rather than letting it through #
In the record
At least one major soil in this section is hydrologic group D, the slowest-infiltrating class. Water tends to run off and pond rather than soak away. For a stock pond or a reservoir that is the ground you want, since it will hold without lining. For a well it cuts the other way, because slow infiltration means slow recharge, and for a septic field it is the same property that makes an absorption bed fail. There are 6 impoundments of record on this ground, which is consistent with soil that holds water.
Expect water to sit rather than soak. It drives the septic answer, the driveway, and where a foundation can go, so walk it in spring rather than in August.

3 things this land will ask of its owner every year #
In the record
Ownership here carries recurring duties, not just one-off diligence. Each of these comes from this section's own records rather than from anything true of rural property generally. The decrees carry the court filings and the plan, the well permits carry any metering, the soil survey carries septic, the well permit's own basin carries any interstate compact duty, and each one has somebody to ask. What none of them has is a published price: the amounts are set by a county board of health, a ditch company, a plan operator and a water lawyer, none of which the state publishes, so this report names the obligation and leaves the number to the quotes it is telling you to get. Ask the seller for last year's invoices against this list; that is the only honest source for what it actually runs.
Add these to the carrying cost before agreeing a price. Water rights that need annual filings and an augmentation assessment cost money to keep whether or not you use the water.

From Colorado's own irrigated-lands mapping (2023): Alfalfa, sprinkler. This is the direct check on an irrigated-acreage claim. The figure is what the ditch or well serves in total, across everyone it delivers to, and it is not this property's acreage.
Confirm the acreage attaches to the parcel you are buying rather than to the structure's whole service area, which usually crosses several owners.

2 well permit(s) here allow irrigation #
In the record
An irrigation-permitted well is materially different from the household-only permit most rural parcels get, and much harder to obtain new. The most recent one here was completed in 1981, so these are historic permits rather than evidence that a new one could be had today: they were granted under conditions that no longer apply, and they attach to the wells that hold them rather than to the ground.
Get the permit number and check it is still live. These are hard to obtain new, so an existing one is part of what you are buying rather than a formality.

6 storage rights of record in this section #
In the record
6 storage rights of record across 6 structures. 5 acre feet decreed absolute and 4 conditional. A decreed reservoir is water you may keep; an undecreed pond is a diversion the state can require you to drain or replace by evaporation. Ask which this is, and whether an augmentation plan covers the evaporative loss.
A storage right is a volume you may keep, which is a different thing from a rate you may divert. Get the decree: the two are often confused in a listing.

Wells here are comfortably above domestic demand: median 15 gpm across 38 completed wells #
Our reading
A house with ordinary indoor use needs something like 5 gpm, so the measured record of neighbouring wells clears that with room. It says nothing about irrigation, which needs an order of magnitude more. These are figures the driller reported at completion and they cluster hard on round numbers, so read the median as a band rather than a measurement.
Yield is not the constraint here. Spend the diligence on what the permit allows instead, which is the thing that actually limits what you can do with it.

Part of this section is federally designated prime farmland #
In the record
USDA classification: Farmland of statewide importance; Not prime farmland; Prime farmland if irrigated; Prime farmland if irrigated and reclaimed of excess salts and sodium. A published designation and a real component of agricultural land value, though it can also bring conservation-program eligibility and, in some counties, subdivision constraints.
Prime farmland matters for what you may be able to do rather than for what is there now: it is the ground conservation easements and agricultural valuations are written against.

A stream that has run every measured year is about as good as surface supply gets. It is the gauge's record, not a guarantee, and the gauge may be some miles off.

Prime farmland, and the water that qualifies it is actually here #
In the record
The USDA classes soil here as prime farmland if irrigated, and Colorado's own irrigated-lands mapping shows 117 acres under irrigation in this section. The condition on the classification is met. That combination is what an appraiser and a conservation easement both look for.
This is the combination that makes farmland: the soil and the water in the same place. Confirm the water conveys with the parcel before paying for the combination.

Context rather than findings: the same in most reports around here, and here so the findings above can be read against them.
63 wells here sit within 600 feet of another #
In the record
Six hundred feet is the statutory spacing for a new well permit, so this is a measure of how crowded the ground already is. A residential well pumping 15 gpm or less is excepted from the rule and can generally still be permitted; anything larger is argued case by case, with the state engineer weighing material injury to existing wells. If the plan needs a well bigger than a house, this is the constraint to ask about first.
Crowded wells draw on each other. Ask the seller what the static level does in August rather than in the spring, and treat a neighbour's new well as a real risk to yours.

The most recent well here was completed in 2024 #
In the record
Somebody has drilled successfully on this ground recently, which is the most direct evidence available that a new well is physically achievable here. A completion report is filed when a well is finished, so this is the drilled record rather than the permitted one.
An old date is not a problem by itself, but it means the depths and yields on this page describe conditions that may have moved since. Weight a recent neighbour's well over an old one.

The wells here sit outside Colorado's named-aquifer system #
In the record
The permits give the aquifer as “all unnamed aquifers”, which is a classification rather than a missing record. Colorado names four bedrock aquifers: Dawson, Denver, Arapahoe and Laramie-Fox Hills. Those are individually adjudicated with their own rules, and the Denver Basin is where that matters. Everywhere else the state does not administer groundwater by formation at all: what governs a well is whether pumping it depletes a stream, which is the tributary question this report answers separately. So the absence of a formation name here is not a gap in the record and there is nothing further to look up; it means the geology is not the thing that decides what you may pump.
Outside the named systems there is no published allocation to lean on, so the state's own figures thin out here. A driller's log from an adjacent parcel is worth more than any map.

Owner of record: HALLIWELL, PHILIP M & BROOKE M #
In the record
From the county assessor roll via Colorado's statewide parcel composite. Last recorded sale Mar 2016 for $729,000. An assessor roll lags a closing by months, so it is who the county last billed, not necessarily who owns it today.
Check the name against the deed and against whoever holds the well permit. Three different names on those three documents is common, and it is where the diligence starts.

Bureau of Land Management land is 0.6 miles away #
In the record
Public land this close is usually part of why a rural property is worth what it is: the view stays, and so does the wildlife. Bordering public land is not a right to use or cross it. Access runs on recorded easements and on the managing agency's travel plan, both of which can change, and a parcel that can only be reached across public ground may have no legal access without one.
Nearby public land is an amenity, and it is also a fire, access and traffic neighbour. Find out which agency and what the management plan allows.

The United States holds no minerals under this ground #
In the record
The federal mineral estate is mapped here and shows no federal interest. That rules out the federal government as a mineral owner. It does not mean the minerals travel with the surface. A private reservation, made when the land was first sold on, leaves no trace in any statewide dataset, and that is a title question for the county clerk and recorder.
Federal ownership is ruled out, which is the cleanest of the possible answers. Private severance is not, and only a title search finds that.

Inside 3 water governing districts, levying 0.5 mills #
In the record
Conservancy and river water conservation districts manage water across a whole basin. They do not supply a parcel. They can levy taxes, and they are the bodies that negotiate for the basin when a compact obligation is at stake. About three quarters of Colorado sits inside one, so this says more about where the parcel is than about the parcel. Certified mill levies: Colorado River Water Conservation District 0.5, Basalt Water Conservancy District 0.055, West Divide Water Conservancy District 0.041.
Governing districts levy, and some of them can levy on this parcel. The mills above are what each has certified; check them against the tax bill.

182 wells have actually been drilled nearby #
In the record
Within 2 miles the state holds records of wells that were actually drilled, not just permitted. Median depth of a completed well here is 110 feet and median tested yield 15 gallons a minute. A permit is only permission. These are holes somebody paid to dig, so they are the better guide to what a new well here would cost and what it would find.
Plenty of people have found water near here, which is the best evidence available short of drilling. It still says nothing about this particular parcel.

Threemile Creek runs year round, 0.65 miles away #
In the record
Mapped by the USGS as perennial, meaning it carries water in a normal year rather than only after snowmelt or a storm. Mapping is not measurement. Whether there is water in it in a dry August is a question for the gauge record above and for the call. And a stream running through the ground gives you no right to divert from it.
Year-round water is an amenity and a constraint at once: it brings setbacks, floodplain rules and somebody else's rights. Find out who is senior on it before planning to use any of it.

Every well permit the state holds in this section, whether or not a well was ever built. A permit is permission to drill, so a row here is not proof of water: the depth, yield and static level are what the driller reported to the state, and the lines beneath each row say which record each figure came from.

What this report does not tell you
- Records resolve to a PLSS section: one square mile, 640 acres. A section is not a parcel. Every count above is “in this section”, and a specific parcel may hold more or fewer of them.
- Most well and right coordinates are DWR's, spotted from section lines or quarter corners rather than surveyed, so a record can land in an adjoining section. The radius figures exist to show the neighborhood rather than to imply a boundary.
- Call exposure, where shown as a DWR figure, is the state's own per-structure analysis over the stated ten-year window. It is how the right has been administered, not a reading of the decree, and it does not account for augmentation, exchanges or substitute supply. Nor is being out of priority the same as being shut off: a curtailment that would not put water where the calling senior needs it is futile and the order is rescinded, so these days are the ceiling on administration rather than a count of days the headgate was closed. The state's analysis covers surface diversions and declines wells, springs and some reservoirs; for those the report says so rather than printing a number.
- Wildfire is a percentile within Colorado, because the USFS raster's scaling factor is unpublished. A percentile makes no claim the source data cannot support.
- Some well figures were read off a scanned form by a vision model, and are labelled “scanned log” where they appear. DWR images these documents but does not put their contents in its API: static water level is in the feed for 6% of wells and yield for 24%, and the missing ones are mostly the old wells where the handwriting is worst. So the choice is a transcribed number or no number. Every such value carries a link to the document image it came from, and a reader relying on one should open it and check the handwriting: a model misreading a 4 as a 9 produces a number that looks exactly as confident as a correct one. Figures from DWR's own feed are labelled “DWR API” and were not transcribed by anything.
- “Unmapped” flood means FEMA never studied the area. It is not a finding of low flood risk.
- The wildland-urban interface classification here is the USFS/SILVIS research layer, by 2020 census block. It is what insurers and mapping use, and it is not the legal designation. The code duty under C.R.S. 24-33.5-1237 turns on the Wildfire Resiliency Code Board's own map under 8 CCR 1507-39, which Colorado publishes as image tiles and as a layer still marked draft. No report can read that map. Whether this ground is inside it, and whether the county has adopted the code, is a question for the county building department.
- This is a records report, not legal advice, a title opinion, or an appraisal. Colorado water is decided on decrees and on the ground; this tells you which decrees to pull. For a legal question about any right in it, the people to ask are the State Engineer's Office and the Water Commissioner for your division.
