Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,400
cubic feet per second (cfs) to 20,000 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 17,372 thousand acre-feet (KAF)
(71 percent of capacity).
Lake Mead storage is 13,317 KAF (51 percent of capacity).
Total system storage is 38,577 KAF (65 percent of capacity).
Lake Powell elevation is 3,651.25 feet.
Yesterday, the average Colorado River flows were 395 cfs near the
Yuma Fourth Avenue Bridge and 738 cfs at the Northerly International
Boundary. The average release from Painted Rock Dam was 0 cfs and
Alamo Dam was 37 cfs. The Morelos Dam diversions for the week of

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.
