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 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 15,277 thousand acre-feet (KAF) (63 percent of
capacity). Lake Mead storage is 10,183 KAF (39 percent of capacity).  Total
system storage is 33,205 KAF (56 percent of capacity). Lake Powell elevation
is 3,633.75 feet.

The observed April-July inflow for the Colorado River is 5.8 million acre-feet or
73 percent of average.

Yesterday, the average Colorado River flows were 1,050 cfs near the Yuma Fourth
Avenue Bridge and 1,307 cfs at the Northerly International Boundary.  The
average release from Painted Rock Dam was 0 cfs and Alamo Dam was 56 cfs.  The
Morelos Dam diversions for the week of 27-Sep-2010 are expected to be 1,127 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.
