Waterflow reports for the Colorado river from Glenn Canyon dam to Parker dam

Lower Colorado River Operations Schedule

Releases from Davis and Parker dams will vary from about 4,400 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 15,329 thousand acre-feet (KAF) (63 percent of capacity). Lake Mead storage is 13,212 KAF (51 percent of capacity). Total system storage is 36,114 KAF (61 percent of capacity). Lake Powell elevation is 3,634.20 feet.

The April-July forecast for the Colorado River is 2.01 million acre-feet or 28 percent of average.

Yesterday, the average Colorado River flows were 1,240 cfs near the Yuma Fourth Avenue Bridge and 1,522 cfs at the Northerly International Boundary. The average release from Painted Rock Dam was 0 cfs and Alamo Dam was 41 cfs. The Morelos Dam diversions for the week of 02-Jul-2012 are expected to be 1,540 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.
