1,190 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

    Ground here is prime farmland, but only if it is irrigated

    93% of sections carry soil the USDA classes as 'prime farmland if irrigated', against 44% across the state. 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.

  2. Stands out

    Towns hold a large share of the water here

    51% of rights allow municipal use, against 10% across the state. Municipal rights are senior more often than not and rarely come back on the market, so they shape what is left for everyone else.

  3. Stands out

    Wells here get plugged and abandoned more than most

    23.4% of well permits end in a plugging, against 9% across the state, 3,625 wells in all. A well sealed shut is the clearest verdict a driller ever files.

  4. Worth knowing

    Wells here have had to be re-drilled deeper

    73 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.

  5. Worth knowing

    Many decrees here name a structure that no longer exists

    14% of rights attach to a structure DWR marks abandoned, historical or non-existent. A decree citing a ditch that is gone is a title problem, not a water supply.

  6. Worth knowing

    Water systems here have unresolved health violations

    5 of this county's 64 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.

  7. Context

    Water here is called out for a large part of the year

    The median right is out of priority 72 days a year on DWR's own analysis. The worst year on record here was 322 days.

  8. Context

    Dams here are rated unsatisfactory

    3 of this county's 77 dams carry an unsatisfactory condition rating. A storage right behind a failing dam is water you cannot count on.

  9. Worth knowing

    Half the wells drilled here never had a pump put in

    66% 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.

  10. Worth knowing

    Nobody measures what most structures here divert

    61% of rights sit on structures where DWR keeps no diversion record. There is no way to check the paper against what actually came through.

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.
