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 23,500 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 15,864 thousand acre-feet (KAF) (65 percent of 
capacity). Lake Mead storage is 10,546 KAF (41 percent of capacity).  Total 
system storage is 34,677 KAF (58 percent of capacity). Lake Powell elevation 
is 3,638.82 feet.

The April-July forecast for the Colorado River is 5.69 million acre-feet or 
72 percent of average.

Yesterday, the average Colorado River flows were 1,525 cfs near the Yuma Fourth
Avenue Bridge and 1,723 cfs at the Northerly International Boundary.  The 
average release from Painted Rock Dam was 7 cfs and Alamo Dam was 50 cfs.  The 
Morelos Dam diversions for the week of 05-Jul-2010 are expected to be 1,710 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.
