Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,600 cubic feet per
second(cfs) to 20,000 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 11,933 thousand acre-feet (KAF) (49 percent of
capacity). Lake Mead storage is 12,504 KAF (48 percent of capacity). Total
system storage is 32,155 KAF (54 percent of capacity). Lake Powell elevation
is 3601.91 feet.
Yesterday, the average Colorado River flows were 1126 cfs near the Yuma Fourth
Avenue Bridge and 1455 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 0 cfs and Alamo Dam was 40 cfs. The
Morelos Dam diversions for the week of 01-Oct-2007 are expected to be 1211 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.
