Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 1,800
cubic feet per second (cfs) to 22,000 cfs during a 24-hour
period. River levels will vary during the 24-hour periods with
the higher levels coinciding with periods of peak hydroelectric
power generation. Levels below the dams are usually highest
during the afternoon and early evening. Average daily releases
may vary in response to changing conditions.
Average daily releases and midnight lake elevations for the week,
as well as anticipated averages for the following 2 weeks, are
scheduled as follows:

Current Lake Powell storage is 16,826 thousand acre-feet (KAF)
(69 percent of capacity).
Lake Mead storage is 13,810 KAF (53 percent of capacity).
Total system storage is 38,490 KAF (65 percent of capacity).
Lake Powell elevation is 3,646.84 feet.
Yesterday, the average Colorado River flows were 759 cfs near the
Yuma Fourth Avenue Bridge and 1,716 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 25 cfs. The Morelos Dam diversions for
the week of 28-Nov-2011 are expected to be 1,612 cfs.
ALL RIVER USERS should remember that fluctuating river flows may
conceal or create natural hazards such as moving sandbars, gravel
bars, unstable riverbanks, floating or submerged debris, or other
unfamiliar obstacles.
Caution should be exercised while using the river between
Davis Dam and the Mexican Border at San Luis, Arizona.
