Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about
1,800 cubic feet per second (cfs) to 16,000 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 17,288 thousand acre-feet (KAF)
(71 percent of capacity).
Lake Mead storage is 13,404 KAF (52 percent of capacity).
Total system storage is 38,541 KAF (65 percent of capacity).
Lake Powell elevation is 3,650.58 feet.
Yesterday, the average Colorado River flows were 567 cfs near the
Yuma Fourth Avenue Bridge and 904 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 36 cfs. The Morelos Dam diversions for
the week of 31-Oct-2011 are expected to be 901 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.
