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 12,884 thousand acre-feet (KAF)
(53 percent of capacity).
Lake Mead storage is 11,123 KAF (43 percent of capacity).
Total system storage is 31,544 KAF (53 percent of capacity).
Lake Powell elevation is 3,611.52 feet.

The April-July forecast for the Colorado River is 9.7 million
acre-feet or 122 percent of average.

Yesterday, the average Colorado River flows were 734 cfs near

Dam was 0 cfs and Alamo Dam was 54 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.
