Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,300 cubic feet per
second (cfs) to 19,200 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 11,941 thousand acre-feet (KAF) (49 percent
of capacity). Lake Mead storage is 13,870 KAF (54 percent of capacity).
Total system storage is 33,516 KAF (56 percent of capacity). Lake Powell
elevation is 3,601.99 feet.
The observed 2006 water year inflow for the Colorado River is 8.774 million
acre-feet or 73 percent of average.
Yesterday, the average Colorado River flows were 698 cfs near the Yuma Fourth
Avenue Bridge and 1,003 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 1 cfs and Alamo Dam was 47 cfs.
The Morelos Dam diversions for the week of 09-Oct-2006 are expected to be
1,165 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.
