Lower Colorado River Operations Schedule



Releases from Davis and Parker dams will vary from about 4,300 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 13,771 thousand acre-feet (KAF) (57 percent of capacity).
Lake Mead storage is 9,378 KAF (36 percent of capacity).  Total system storage is 31,377
KAF (53 percent of capacity).  Lake Powell elevation is 3,620.07 feet.

The April-July unregulated inflow forecast for the Colorado River is 6.65 million acre-
feet or 93 percent of average.

Yesterday, the average Colorado River flows were 1,230 cfs near the Yuma Fourth Avenue
Bridge and 1,529 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 25-Jul-2016 are expected to be 1,405 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.
