Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 8,000 cubic feet
per second (cfs) to 22,000 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 11,926 thousand acre-feet (KAF) (49 percent
of capacity). Lake Mead storage is 13,928 KAF (54 percent of capacity).
Total system storage is 33,634 KAF (57 percent of capacity). Lake Powell
elevation is 3,601.84 feet.
The Projected 2006 Water Year forecast for the Colorado River is 8.705 million
acre-feet or 72 percent of average.
Yesterday, the average Colorado River flows were 1,003 cfs near the Yuma Fourth
Avenue Bridge and 1,310 cfs at the Northerly International Boundary. The
average release from Painted Rock Dam was 1 cfs and Alamo Dam was 48 cfs.
The Morelos Dam diversions for the week of September 25, 2006 are expected to
be 1,500 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.
