PROJECTED LOWER COLORADO RIVER OPERATIONS SCHEDULE

Releases from Davis and Parker dams will vary from about 8,000 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:

Date Parker Dam Average Releases (cfs)
Lake Havasu Elev.
(ft)
Davis Dam Average Release (cfs) Lake Mohave Elev.

Current Lake Powell storage is 16,062 thousand acre-feet (KAF) (66 percent of capacity). Lake Mead storage is 17,502 KAF (68 percent of capacity). Total system storage is 40,537 KAF (68 percent of capacity). Lake Powell elevation is 3640.5 feet.

The Projected April-July forecast for the Colorado River is 3.4 million acre-feet or 29 percent of average as of 03-July-2002.

Yesterday, the average Colorado River flows were 981 cfs near the Yuma Fourth Avenue Bridge and 1,800 cfs at the Northerly International Boundary. The average release from Painted Rock Dam was 7 cfs and Alamo Dam was 40 cfs. The Morelos Dam diversions for the week of July 7, 2002 are expected to be 1,978 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.
