Releases
from Davis and Parker dams will vary from about 4,600 cubic feet per second
(cfs) to 23,000 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
average for the following 2 weeks, are scheduled as follows:

Current Lake Powell
storage is 11,988 thousand acre-feet (KAF) (49 percent of capacity). Lake
Mead storage is 15,478 KAF (60 percent of capacity). Total system storage
is 35,361 KAF (60 percent of capacity). Lake Powell elevation is 3,602.48
feet.
The
Projected inflow volume into Lake Powell for the April-July period for the
Colorado River is 9.0 million acre-feet or 113 percent of average.
Yesterday,
the average Colorado River flows were 633 cfs near the Yuma Fourth Avenue
Bridge and 1,390 cfs at the Northerly International Boundary. The average
release from Painted Rock Dam was 990 cfs and Alamo Dam was 172 cfs. The
Morelos Dam diversions for the week of 27-Jun-2005 are expected to be 1,970
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 be exercised
while using the river between Davis Dam and the Mexican Border at San Luis,
Arizona.
