The August 2022 24-Month Study modeled 2023 and 2024 operations at Lakes Powell and Mead as if the 0.480 maf had been delivered to Lake Mead for operating tier/condition purposes both for the U.S. Lower Basin and for Mexico. Winter Storm Warnings are in effect for elevations above 4000.Heavy accumulations of 10-20 are forecast above 6000, 3-8 to 4500 and several inches to valley floors. In addition to the February 2023 24-Month Study based on the Most Probable inflow scenario, and in accordance with the Drought Response Operational Agreement (DROA)), Reclamation has conducted model runs in February to determine a possible range of reservoir elevations.
