Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,500 cubic
feet per second (cfs) to 24,000 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 15,339 thousand acre-feet (KAF)
(63 percent of capacity). Lake Mead storage is 10,063 KAF
(39 percent of capacity). Total system storage is 32,961 KAF
(56 percent of capacity). Lake Powell elevation is 3,634.29 feet.
Yesterday, the average Colorado River flows were 1,160 cfs near the
Yuma Fourth Avenue Bridge and 1,345 cfs at the Northerly International
Boundary. The average release from Painted Rock Dam was 0 cfs and
Alamo Dam was 38 cfs. The Morelos Dam diversions for the week of
18-Oct-2010 are expected to be 1,197 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.
