Releases from Davis and Parker dams will vary from about 8,000 cubic feet per second (cfs) to 22,000 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 average for the following 2 weeks, are scheduled as follows:

Current Lake Powell storage is 12,221 thousand acre-feet (KAF) (50 percent of capacity). Lake Mead storage is 15,306 KAF (59 percent of capacity). Total system storage is 35,683 KAF (60 percent of capacity). Lake Powell elevation is 3,604.87 feet.

The total volume from the Colorado River into Lake Powell for the April through July period was 8.81 million acre-feet or 111 percent of average.

Yesterday, the average Colorado River flows were 1,100 cfs near the Yuma Fourth Avenue Bridge and 1,355 cfs at the Northerly International Boundary. The average release from Painted Rock Dam was 0 cfs and Alamo Dam was 4 cfs. The Morelos Dam diversions for the week of August 22, 2005 are expected to be 1,310 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.
