Bureau of Reclamation 24-Month Study Results for Lake Powell and Lake Mead
The 24-Month Study, issued by the Bureau of Reclamation, projects future conditions in the Colorado River system extending out 24 months. The Minimum, Most, and Maximum probable elevations are determined using the 90%, 50%, and 10% probable exceedance of unregulated inflow forecasts from the Colorado Basin River Forecast Center, projected reservoir operations as determined by existing policies, and projected water demand schedules.
