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 17,667 thousand acre-feet (KAF)
(73 percent of Capacity).
Lake Mead storage is 11,803 KAF (46 percent of capacity).
Total system storage is 37,716 KAF (64 percent of capacity).
Lake Powell elevation is 3,653.59 feet.

The April-July forecast for the Colorado River is 12.00 million
acre-feet or 151 percent of average.

Yesterday, the average Colorado River flows were 827 cfs near the
Yuma Fourth Avenue Bridge and 1,932 cfs at the Northerly
International Boundary.  The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 50 cfs.  The Morelos Dam diversions for
the week of 11-Jul-2011 are expected to be 1,854 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.
