Lower Colorado River Operations Schedule
Releases from Davis and Parker dams will vary from about 4,500
cubic feet per second (cfs) to 24,000 cfs during a 24-hour
period. River levels will vary during the 24-hour periods with
the 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.
Average 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 12,711 thousand acre-feet (KAF)
(52 percent of capacity).
Lake Mead storage is 11,159 KAF (43 percent of capacity).
Total system storage is 31,408 KAF (53 percent of capacity).
Lake Powell elevation is 3,609.81 feet.
The April-July forecast for the Colorado River is 9.5 million
acre-feet or 120 percent of average.
Yesterday, the average Colorado River flows were 1,730 cfs near

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.
