Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 1,700
cubic feet per second (cfs) to 15,000 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 14,857 thousand acre-feet (KAF)
(61 percent of capacity). Lake Mead storage is 9,958 KAF
(38 percent of capacity). Total system storage is 32,335 KAF
(54 percent of capacity). Lake Powell elevation is 3,630.04 feet.
Yesterday, the average Colorado River flows were 679 cfs near the
Yuma Fourth Avenue Bridge and 2,040 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 24 cfs. The Morelos Dam diversions for
the week of 06-Dec-2010 are expected to be 1,911 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.
