How Parker Dam Releases Regulate Flow Below Lake Havasu
Parker Dam re-regulates releases from Hoover and Davis dams , helping smooth Colorado River flow for downstream water users. Hourly releases can therefore vary while the daily series summarizes the full operating day.
The official projected schedule is published hour by hour in Mountain Standard Time and is expressly subject to change.
The generating-unit count shown here is estimated from release volume. It does not account for every path water may take through or around Parker Dam.
One cubic foot per second sustained for a full day is about 1.98 acre-feet. Recorded and forecast values remain separately labeled because operating schedules can be revised.
Data Sources and Update Schedule
The Parker Dam cards require exact Arizona dates; if hourly source rows have not arrived,
the 24-hour schedule is marked unavailable instead of borrowing another day’s rows.
Source records may be provisional and revised. Forecasts are planning information, not guaranteed outcomes.
