Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,500 cubic feet
per second (cfs) to 19,000 cfs during a 24-hour period. River levels will
vary during the 24-hourperiods 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 11,546 thousand acre-feet (KAF) (47 percent of
capacity). Lake Mead storage is 14,040 KAF (54 percent of capacity). Total
system storage is 33,294 KAF (56 percent of capacity). Lake Powell elevation
is 3597.85 feet.
The Projected April-July forecast for the Colorado River is 4.7 million acre-
feet or 59 percent of average.
Yesterday, the average Colorado River flows were 816 cfs near the Yuma Fourth
Avenue Bridge and 3258 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 8 cfs and Alamo Dam was 41 cfs. The
Morelos Dam diversions for the week of 26-Mar-2007 are expected to be 3450 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.
