Current Lake Powell storage is 19,217 thousand acre-feet (KAF) (79 percent of
capacity). Lake Mead storage is 20,037 KAF (77 percent of capacity). Total system
storage is 46,736 KAF (79 percent of capacity). Lake Powell elevation is 3665.45
feet.
The
Observed April-July forecast for the Colorado River was 4.3 million acre-feet
or 56 percent of average as of 10-Sept-2001.
Yesterday,
the average Colorado River flows were 1,380 cfs near the Yuma Fourth Avenue
Bridge and 1,700 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 September 17th are expected to be 1,500 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.
