921 surveyed sections, drawn one square mile to a square. The shading is scaled against every county in Colorado, so a colour means the same thing on any of these pages. The outline is the county boundary from the Census Bureau: ground inside the line and outside the shading is ground nobody has drilled, filed on or addressed. Aerial imagery is the USGS National Map.
Stands out
This is farming country and the water is committed to it
Structures here serve 204,960 mapped irrigated acres, against 32,919 ac across the state. That acreage is what the decreed water is already doing, so a new use competes with it rather than adding to it.

Worth knowing
Water here usually needs an augmentation plan to be legal
0.5% of rights sit under an augmentation plan, against 0% across the state. Replacement water has to come from somewhere and is almost always paid for, every year, and the obligation runs with the land.
CDSS water rights, net amounts 3 of 22 counties

Stands out
A listing's priority date will overstate seniority here
47% of water rights were decreed more than a decade after the water was first claimed, against 30% across the state. Listings quote the claim date. A call is administered on the decree date, and the median gap here is 23 years.
CDSS water rights, net amounts 5 of 60 counties
47% here 5th of 60 One bar per Colorado county from lowest to highest. Point at one to name it.
Worth knowing
Wells here have had to be re-drilled deeper
37 wells carry a later record more than 20% deeper than their first. Colorado publishes no water-level trend, so a well going back down is the closest thing to one.

Worth knowing
Water systems here have unresolved health violations
3 of this county's 9 community water systems carry a health-based violation that has not been returned to compliance. Health-based means contamination or a treatment failure, not late paperwork.

Stands out
The senior water here was claimed before Colorado was a state
The oldest appropriation on record in this county is 1850, which predates statehood in 1876. Seniority is the whole of Colorado water law and it is absolute: a right from the 1850s is in front of everything filed since, every year, in every dry year.

Context
A lot of this county is wet ground
56% of sections carry poorly drained soil, meaning a water table close to the surface for part of the year. A foundation and septic constraint, and often the most productive ground on a property.

Context
Ground here is prime farmland, but only if it is irrigated
36% of sections carry soil the USDA classes as 'prime farmland if irrigated'. That qualifier is the whole sentence: the soil is excellent and the classification depends on water reaching it. It is what an appraiser and a conservation easement both test against.

This is the county. Your question is probably a property.
None of the above is about a particular parcel. Water is not parcel-shaped: the ditch serving the ground runs through other people's land and the senior right that curtails it sits somewhere else, which is why the state files by survey section rather than by property. Check an address and you get the square mile it sits in, with the wells, the rights and what was actually diverted.
