Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,000
cubic feet per second (cfs) to 18,500 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 13,187 thousand acre-feet (KAF)
(54 percent of capacity).
Lake Mead storage is 11,132 KAF (43 percent of capacity).
Total system storage is 31,808 KAF (54 percent of capacity).
Lake Powell elevation is 3,614.48 feet.
The April-July forecast for the Colorado River is 9.2 million
acre-feet or 116 percent of average.
Yesterday, the average Colorado River flows were 949 cfs near
the Yuma Fourth Avenue Bridge and 2,949 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 39 cfs. The Morelos Dam diversions
for the week of 07-Mar-2011 are expected to be 2,969 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.
