Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 1,600
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 15,899 thousand acre-feet (KAF)
(65 percent of capacity).
Lake Mead storage is 14,927 KAF (57 percent of capacity).
Total system storage is 38,573 KAF (65 percent of capacity).
Lake Powell elevation is 3,639.12 feet.
The April-July forecast for the Colorado River is 5.05 million
acre-feet or 71 percent of average.
Yesterday, the average Colorado River flows were 617 cfs near the
Yuma Fourth Avenue Bridge and 1,677 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 25 cfs. The Morelos Dam diversions
for the week of 09-Jan-2012 are expected to be 1,751 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.
