Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,600 cubic feet
per second cfs) to 24,000 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 11,617 thousand acre-feet (KAF) (48 percent
of capacity). Lake Mead storage is 13,951 KAF (54 percent of capacity).
Total system storage is 33,360 KAF (56 percent of capacity). Lake Powell
elevation is 3598.60 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 1185 cfs near the Yuma
Fourth Avenue Bridge and 3398 cfs at the Northerly International Boundary.
The average release from Painted Rock Dam was 10 cfs and Alamo Dam was 41 cfs.
The Morelos Dam diversions for the week of 02-Apr-2007 are expected to be 3530
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.
