Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 8,000 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 12,585 thousand acre-feet (KAF) (52 percent of
capacity). Lake Mead storage is 14,066 KAF (54 percent of capacity). Total
system storage is 34,687 KAF (58 percent of capacity). Lake Powell elevation
is 3608.55 feet.
The Projected April-July forecast for the Colorado River is 5.3 million acre-
feet or 67 percent of average.
Yesterday, the average Colorado River flows were 600 cfs near the Yuma Fourth
Avenue Bridge and 2,109 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 1 cfs and Alamo Dam was 49 cfs. The
Morelos Dam diversions for the week of 24-Jul-2006 are expected to be 1700 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.
