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 13,585 thousand acre-feet (KAF)
(56 percent of capacity).
Lake Mead storage is 10,908 KAF (42 percent of capacity).
Total system storage is 32,012 KAF (54 percent of capacity).
Lake Powell elevation is 3,618.31 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 641 cfs near
the Yuma Fourth Avenue Bridge and 2,416 cfs at the Northerly
International Boundary. The average release from Painted Rock Dam
was 0 cfs and Alamo Dam was 39 cfs. The Morelos Dam diversions
for the week of 14-Feb-2011 are expected to be 2,540 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.
