Colorado’s water resources supply water not only to the state itself, but also to many surrounding states. With a population that increased from one to five million during the last century, water has been and is the key resource that controls sustainable growth. The CGS plays a leading role in studying how geology and human activities impact Colorado’s important groundwater resources. Colorado is a headwater state, home to the headwaters of four major river systems: the Arkansas, the Colorado, the Platte, and the Rio Grande. However, 80% of the state’s water resources occur in the western part of the state while more than 80% of the population lies in the more arid eastern part of the state, a region that is more dependent on groundwater resources.

Intro

As a non-regulatory agency, the CGS conducts scientific studies of the state’s aquifer systems and investigates natural, “background” conditions of water quality, quantity, and movement. We are currently producing comprehensive geology and groundwater studies county-by-county tailored to inform the public, planners, and policy-makers on the intricacies of local geology and groundwater resources. CGS hydrogeologists serve as scientific advisors to Colorado’s nine Basin Roundtables under the InterBasin Compact Committee (IBCC). Our award-winning 2003 Colorado Groundwater Atlas provided a comprehensive look at groundwater and its geological, hydrological, and legal context in the state. A fully updated online Atlas, with an initial deployment in January 2020, is an ongoing project that provides up-to-date information on groundwater resources across the state. The CGS also studies the effects of historic mining on water quality.
