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 25,000 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 15,753 thousand acre-feet (KAF)
(65 percent of capacity).
Lake Mead storage is 11,509 KAF (44 percent of capacity).
Total system storage is 35,105 KAF (59 percent of capacity).
Lake Powell elevation is 3,637.87 feet.

The April-July forecast for the Colorado River is 12.60 million

International Boundary.  The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 50 cfs.  The Morelos Dam diversions
for the week of 20-Jun-2011 are expected to be 1,786 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.
