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.

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 21,704 thousand acre-feet (KAF) (89 percent of capacity).
Lake Mead storage is 23,256 KAF (90 percent of capacity). Total system storage
is 52,927 KAF (89 percent of capacity). Lake Powell elevation is 3683.0 feet.
Yesterday,
the average Colorado River flows were 900 cfs near the Yuma Fourth Avenue Bridge
and 2,300 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 July 17th are expected to be 2,380 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.
