Reading the scenarios

Minimum Probable is the lower published planning path.

Most Probable is a planning trace, not a guarantee.

Maximum Probable appears when the publication includes it.

CRMMS frequencies count ensemble traces below a level. They are not forecast probabilities.

Lake Mead reviews

Published reviews explain the studies shown above.

Sources, dates, and limitations

The 24-Month Study provides elevation, release, and hydropower scenarios. CRMMS provides Lake Mead elevation traces. Both are planning information, not guarantees.
