Releases from Davis and Parker dams will vary from about 4,000 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 15,632 thousand acre-feet (KAF) (64 percent of capacity). Lake Mead storage is 13,541 KAF (52 percent of capacity). Total system storage is 36,761 KAF (62 percent of capacity). Lake Powell elevation is 3636.83 feet.

The April-July forecast for the Colorado River is 2.26 million acre-feet or 32 percent of average.

Yesterday, the average Colorado River flows were 1,090 cfs near the Yuma Fourth Avenue Bridge and 1,377 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 04-Jun-2012 are expected to be 1,509 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 exercised while using the river between Davis Dam and the Mexican Border at San Luis, Arizona.
