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)

Current Lake Powell storage is 20,097 thousand acre-feet (KAF) (83 percent of capacity). Lake Mead storage is 20,436 KAF (79 percent of capacity). Total system storage is 48,274 KAF (81 percent of capacity). Lake Powell elevation is 3671.9 feet.

Yesterday, the average Colorado River flows were 2,600 cfs near the Yuma Fourth Avenue Bridge and 780 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 July 16th are expected to be 2,020 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.
