Reservoir outlook
Projected Elevation
Month-by-month Lake Mead elevation scenarios, measured in feet.
Planning outlook & analysis
24-Month Study and CRMMS Projections
Put reservoir elevation, dam releases, and hydropower on the same planning horizon. Select a lake, compare the available 24-Month Study scenarios, and read the analysis that explains why a change or threshold matters.

July 2026 24-Month Study
The charts use the scenarios actually included in the selected publication. A missing Maximum Probable line does not make a Most and Minimum Probable study incomplete.
River operations
Projected Releases
Month-by-month Hoover Dam average release scenarios, measured in cubic feet per second.
Powerplant outlook
Projected Hydropower
Month-by-month Hoover Dam generation scenarios, measured in megawatt-hours.
Read scenarios carefully
A scenario line is not a probability
Minimum Probable shows the lower published planning path when that scenario is available.
Most Probable is the central planning trace, not a guaranteed outcome.
Maximum Probable appears only when the source publication includes it.
CRMMS frequencies show how many of the 30 ensemble traces fall below a level; they are not a guaranteed-outcome probability.

July 2026 CRMMS pool elevations
Follow all 30 modeled traces for Lake Mead and Lake Powell, then see how often each monthly result falls below a critical elevation. Trace 4 is the source column labeled 2020 and trace 33 is the source column labeled 1991.

Share of ensemble traces below each level
Each percentage is the number of the 30 traces below the level on that date. It describes this model ensemble, not the probability of a guaranteed outcome.
