Current
Lake Powell storage is 14,558 thousand acre-feet (KAF) (60 percent of capacity).
Lake Mead storage is 17,139 KAF (66 percent of capacity). Total system storage
is 38,167 KAF (64 percent of capacity). Lake Powell elevation is 3627.35 feet.
The
Projected April - July forecast for the Colorado River is 2.9 million acre-feet
or 24 percent of average as of 09-19-2002.
Yesterday,
the average Colorado River flows were 1,265 cfs near the Yuma Fourth Avenue

for the week of September 23, 2002 are expected to be 1,550 cfs.
All

while using the river between Davis Dam and the Mexican Border at San Luis,
Arizona.
