About Lake Mead Water Levels

Lake Mead is the Lower Basin's largest storage reservoir. Its elevation responds to Colorado River inflow, evaporation, water deliveries, and releases through Hoover Dam.

The daily forecast is an operating-data snapshot; the monthly table is the Most Probable 24-Month Study scenario. They have different publication schedules and should not be expected to match date for date.

Historic lines show recorded conditions. Forecast lines can change whenever the Bureau of Reclamation publishes a new operating or planning outlook.

Important Lake Mead Elevation Levels

The blue water layer is scaled from 640 feet at the lakebed to the 1,220-foot full-capacity line and updates with the current elevation.
