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 4,300 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  11,767 thousand acre-feet (KAF) (48 percent of
capacity). Lake Mead storage is 13,505 KAF (52 percent of capacity).  Total
system storage is  33,151 KAF (56 percent of capacity). Lake Powell elevation
is 3600.18 feet.

The Projected April-July forecast for the Colorado River is 4.2 million acre-
feet or 53 percent of average.

Yesterday, the average Colorado River flows were 725 cfs near the Yuma Fourth
Avenue Bridge and 2,525 cfs at the Northerly International Boundary.  The
average release from Painted Rock Dam was 13 cfs and Alamo Dam was 18 cfs. The
Morelos Dam diversions for the week of 30-Apr-2007 are expected to be 1,990 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.
