Releases from Davis and Parker dams will vary from about 4,500
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 18,261 thousand acre-feet (KAF)
(75 percent of capacity).
Lake Mead storage is 12,484 KAF (48 percent of capacity).
Total system storage is 39,194 KAF (66 percent of capacity).
Lake Powell elevation is 3,658.22 feet.

The observed April-July inflow for the Colorado River is 12.92
million acre-feet or 163 percent of average.

Yesterday, the average Colorado River flows were 1,080 cfs near
the Yuma Fourth Avenue Bridge and 1,370 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 22-Aug-2011 are expected to be 1,310 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.
