In the San Luis Valley, a well in Conejos County comes with groundwater rules

A well sounds like simple, private water. In the San Luis Valley, including Conejos County, it comes with more structure than that.

The valley is its own state water division, Division 3, and the aquifer beneath it has been pumped hard over the years. To protect senior surface-water rights and help the aquifer recover, the state adopted well rules for the valley, and irrigators have formed groundwater management subdistricts. One of those subdistricts covers wells along the Conejos River. A subdistrict is a way for a group of well owners to make up for the water their pumping takes from streams, instead of each well being regulated alone.

For a buyer, the takeaway is plain: “has a well” is not the same as “unlimited water.” A well may be exempt (often a household well with limits) or non-exempt, and a non-exempt well may sit inside a subdistrict with its own dues and conditions. These details ride with the parcel, not with good intentions.

Before counting on a well, confirm the permit, whether it is exempt or non-exempt, and any subdistrict it falls under. The state Division of Water Resources, Division 3 office, is the place to check.
