Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 1,800
cubic feet per second (cfs) to 15,000 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 13,751 thousand acre-feet (KAF) (57 percent of capacity).
Lake Mead storage is 10,786 KAF (42 percent of capacity).
Total system storage is 32,079 KAF (54 percent of capacity).
Lake Powell elevation is 3,619.88 feet.
The April-July forecast for the Colorado River is 9.0 million
acre-feet or 113 percent of average.
Yesterday, the average Colorado River flows were 888 cfs near the
Yuma Fourth Avenue Bridge and 2,447 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 4 cfs and Alamo Dam was 39 cfs. The Morelos Dam diversions
for the week of 07-Feb-2011 are expected to be 2,460 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.
