Lower Colorado Region

Automated* Lower Colorado River Operations Schedule

Releases from Davis dam may vary from between a 1-unit flow (4,200 cfs) to a 5-unit flow (23,000 cfs). Releases from Parker dam may vary from between a 1/2-unit flow (1,800 cfs) to a 4-unit flow (19,000 cfs). Seasonal minimum and maximum releases vary to coincide with downstream municipal and agricultural water demands. Releases are at their lowest during the late fall and winter seasons, and they are at their highest during the late spring and summer seasons.

Daily releases are made to meet downstream municipal and agricultural water demands while hourly releases are made to coincide with peak hydropower demand. River levels on the lower Colorado River vary based on Hoover, Davis, and Parker dam releases. Scheduled releases may vary in response to changing conditions, maintenance, and unforeseen circumstances. Current observed and projected average daily and hourly releases and midnight lake elevations for the week, as well as anticipated averages for the near future are shown in the tables and graphs that follow.
