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 4,500
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:
