Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,500 cubic feet
per second (cfs) to 23,000 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 12,313 thousand acre-feet (KAF) (51 percent of
capacity). Lake Mead storage is 14,001 KAF (54 percent of capacity). Total
system storage is 34,323 KAF (58 percent of capacity). Lake Powell elevation
is 3,605.81 feet.
The observed April-July runoff for the Colorado River was 5.32 million acre-
feet or 67 percent of average.
Yesterday, the average Colorado River flows were 873 cfs near the Yuma Fourth
Avenue Bridge and 1374 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 1 cfs and Alamo Dam was 45 cfs. The
Morelos Dam diversions for the week of 14-Aug-2006 are expected to be 1490 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.
