Live water rights. Decreed rights still on the books. This is where the paper water is, which is not the same map as where anybody drilled.

757 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.

  1. Stands out

    A listing's priority date will overstate seniority here

    49% 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 24 years.

  2. Stands out

    A lot of this county is wet ground

    82% of sections carry poorly drained soil, against 40% across the state, 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.

  3. Worth knowing

    Water systems here have unresolved health violations

    3 of this county's 4 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.

  4. Stands out

    Every town here drinks the same water a well would draw

    All 4 of this county's community water systems run on groundwater rather than surface water. A municipal supply is the best-monitored well in the county, so its record is the closest thing to a free test of the aquifer under this ground.

  5. Context

    Half the wells drilled here never had a pump put in

    56% of constructed wells have no pump installation on record. Somebody paid to drill a hole and walked away from it. A permit says you may drill; this is what happened when people did.

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.
