Current Lake Powell storage is 20,097 thousand acre-feet (KAF) (83 percent
of capacity). Lake Mead storage is 20,436 KAF (79 percent of capacity). Total
system storage is 48,274 KAF (81 percent of capacity). Lake Powell elevation
is 3671.9 feet.
Yesterday,
the average Colorado River flows were 2,600 cfs near the Yuma Fourth Avenue
Bridge and 780 cfs at the Northerly International Boundary. The average release
from Painted Rock Dam was 0 cfs and Alamo Dam was 50 cfs. The Morelos Dam
diversions for the week of July 16th are expected to be 2,020 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 be exercised while using the river between Davis Dam and the Mexican Border
at San Luis, Arizona.
