Understanding Hydropower Energy
One megawatt-hour is the energy produced by one megawatt of output for one hour. Hourly charts show when generation occurs; daily totals add the energy from the full day.
Water releases and energy do not always change at the same rate. Generating-unit schedules, plant conditions, and water routed outside generating units can affect the result.
Data Sources and Update Schedule
Recorded reservoir and dam values come from Bureau of Reclamation Lower Colorado River operations data. Planning projections come from the agency's monthly reservoir study. This page updates as new source records are collected and always shows the relevant record or publication date.
