Along the South Platte in Sedgwick County, well water is tied to the river

Many wells in the Julesburg area draw from the South Platte alluvial aquifer, which Colorado administers as part of the river — so a well here is not the same as unlimited water.

In Sedgwick County, the South Platte River and the shallow water beneath the valley floor are closely connected. The state treats much of that groundwater as part of the river system, not as a separate private pool. That has a real effect on what a well here can and cannot do.

Colorado administers water by priority, and wells near the South Platte fall under Water Division 1. A well permit spells out the allowed uses — for example, household use, or stock, or irrigation — and it can come with conditions. Some wells that pull from the river system need an augmentation plan, which replaces the water they take so older, senior water rights downstream are not shorted.

Why this matters before you buy: “the property has a well” does not automatically mean you can water a large garden, fill a pond, or irrigate acreage. The permit, its allowed uses, and any conditions are what count — and those travel with the well, not with hopes for the land.

Before counting on a well in the Julesburg area, look up the permit and its conditions with the state’s Division of Water Resources.
