Lower Colorado River Operations Schedule
Releases from
Davis and Parker Dams will vary from about 8,000 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:

Parker Dam Average Release (cfs) |
Lake Havasu Elev. (cfs) |
Davis Dam Average Release (cfs) |
Lake Mohave Elev. (ft) |

Current Lake
Powell storage is 21,932 thousand acre-feet (KAF) (90 percent of capacity).
Lake Mead storage is 24,801 KAF (96 percent of capacity). Total system storage
is 54,603 KAF (92 percent of capacity). Lake Powell elevation is 3684.6 feet.
Yesterday,
the average Colorado River flows were 2,560 cfs near the Yuma Fourth Avenue
Bridge and 4,840 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 Dec 6th are expected to be 1,770 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.
