Current
Lake Powell storage is 20,202 thousand acre-feet (KAF) (83 percent of capacity).
Lake Mead storage is 22,354 KAF (86 percent of capacity). Total system storage
is 49,759 KAF (84 percent of capacity). Lake Powell elevation is 3672.6 feet.
Yesterday,
the average Colorado River flows were 900 cfs near the Yuma Fourth Avenue Bridge
and 2,900 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 December 10th are expected to be 2,330 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.
