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 4,500 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 13,619 thousand acre-feet (KAF) (56 percent of 
capacity). Lake Mead storage is 11,429 KAF (44 percent of capacity).  Total 
system storage is 32,565 KAF (55 percent of capacity). Lake Powell elevation 
is 3,618.63 feet.

The April-July forecast for the Colorado River is 5.2 million acre-feet or 66 
percent of average.

Yesterday, the average Colorado River flows were 1,590 cfs near the Yuma Fourth Avenue 
Bridge and 2,553 cfs at the Northerly International Boundary.  The average release from 
Painted Rock Dam was 2,630 cfs and Alamo Dam was 50 cfs.  The Morelos Dam diversions 
for the week of 19-Apr-2010 are expected to be 2,550 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.
