How Hoover Dam Hydropower Is Reported
Hoover's public series on this site is daily plant energy, so this page reports exact daily MWh totals and planning forecasts rather than claiming an hourly Hoover feed.
Generation depends on both water flow and hydraulic head at Lake Mead, along with which plant units are available. Release volume and energy therefore do not move in a fixed one-to-one ratio.
One megawatt-hour is the energy produced by one megawatt of output for one hour. Recorded values and forecasts are labeled separately because schedules and plant conditions can change.
Data Sources and Update Schedule
Hoover Dam energy is reported here as recorded and forecast daily megawatt-hours from Bureau of Reclamation operations data. The page does not imply hourly detail that the collected Hoover series does not provide.
- Lower Colorado River daily operations report
- Lower Colorado River water data
- Monthly reservoir planning studies
Source records may be provisional and revised. Forecasts are planning information, not guaranteed outcomes.
