An Eagle County well is a permit with limits, not an unlimited water supply
Water in Eagle County is administered by the state under Colorado's prior appropriation system, and a well permit comes with conditions on how much you can use and for what.

If you are looking at a mountain property in Eagle County that runs on a well, it helps to know what that well actually is. In Colorado, water is a state-administered resource. The Division of Water Resources permits wells and tracks water rights, and Eagle County falls in Water Division 5, the part of the state drained by the Colorado River and its tributaries, including the Eagle River.
A well permit is not a promise of unlimited water. Colorado uses the prior appropriation system, often summed up as “first in time, first in right.” Many household wells are permitted only for certain uses, and the permit spells out what those are. Some allow indoor household use only. Others may allow limited outdoor watering or livestock, depending on the permit type and the conditions attached to it.
That difference matters before you buy. A parcel that “has a well” might still be limited in whether you can irrigate a pasture, fill a pond, or serve more than one home. The way to know is to look up the specific permit, not to assume.
You can check a well’s permit and its conditions through the state’s Division of Water Resources, and reach the Division 5 office for questions about the Eagle River basin.
