2,520 surveyed sections, drawn 2 by 2 miles 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.

  1. Stands out

    Nobody pipes water in this county

    There is no active community water system anywhere on the federal register here, so every property is on a well, a cistern, or a shared private supply.

  2. Worth knowing

    Much of this county sits in a designated groundwater basin

    67% of well permits are inside NORTHERN HIGH PLAINS, where new permits are restricted or unavailable. Before anything else about water here, find out whether you can get one.

  3. Worth knowing

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

    71% 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.

  4. Context

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

    The median right is out of priority 79 days a year on DWR's own analysis. The worst year on record here was 206 days.

  5. Worth knowing

    Wells here get plugged and abandoned more than most

    15.0% of well permits end in a plugging, 390 wells in all. A well sealed shut is the clearest verdict a driller ever files.

  6. Stands out

    Every town here drinks the same water a well would draw

    All 2 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.

  7. Context

    A lot of this county is wet ground

    27% 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.

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.
