New Colorado Groundwater Atlas released
ON-010 Colorado Groundwater Atlas
An aquifer is a layer of permeable rock that holds groundwater that can be extracted through water wells. One of the largest groundwater aquifers in the world, the Ogallala Aquifer, is partially located in eastern Colorado. Colorado’s aquifers are one of its most valuable resources that the CGS helps to manage.
