CAP Hydrologic Models
The Colorado River Basin has the two largest reservoirs in the United States – Lake Powell and Lake Mead – which are operated under a system called conjunctive management.
In order to determine the current and potential future health of the reservoirs and our water supply, hydrologists use various “models.”
CAP uses three hydrologic models to provide a glimpse into the water future for the Colorado River Basin – the 24-Month Study, Mid-Term Probabilistic Operations Model and Colorado River Simulation System.
The Arizona Reconsultation Committee is working to develop Arizona’s guiding principles as new operating rules are being developed for the Colorado River Basin to take effect in 2026.
The Committee has convened a technical work group, the Modeling and Analysis Work Group, to use information from these hydrologic models to help inform the Committee’s proposals and recommendations.
