Waterflow reports for the Colorado river from Glenn Canyon dam to Parker dam

Lower Colorado River Operations Schedule

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 averages for the following 2 weeks, are scheduled as follows:

Current Lake Powell storage is 15,620 thousand acre-feet (KAF) (64 percent of
capacity). Lake Mead storage is 10,928 KAF (42 percent of capacity).  Total
system storage is 34,655 KAF (58 percent of capacity).  Lake Powell elevation
is 3,636.73 feet.

The observed April-July inflow for the Colorado River is 7.814 million acre-
feet or 99 percent of average.

Yesterday, the average Colorado River flows were 1,144 cfs near the Yuma Fourth
Avenue Bridge and 1,313 cfs at the Northerly International Boundary.  The
average release from Painted Rock Dam was 0 cfs and Alamo Dam was 66 cfs.  The
Morelos Dam diversions for the week of 14-Sep-2009 are expected to be 1,300 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.
