Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,500 cubic feet
per second (cfs) to 22,800 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 11,804 thousand acre-feet (KAF) (49 percent of
capacity). Lake Mead storage is 13,376 KAF (52 percent of capacity). Total
system storage is 33,111 KAF (56 percent of capacity). Lake Powell elevation is
3,600.56 feet.
The Projected April-July forecast for the Colorado River is 4 million acre-feet
or 50 percent of average.
Yesterday, the average Colorado River flows were 952 cfs near the Yuma Fourth
Avenue Bridge and 1,798 cfs at the Northerly International Boundary. The average
release from Painted Rock Dam was 10 cfs and Alamo Dam was 0 cfs. The Morelos Dam
diversions for the week of 07-May-2007 are expected to be 1,655 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.
