Glen Canyon Dam Operations

Releases from Glen Canyon Dam in September 2007 will average 10,100 cubic feet per second (cfs) with a total of 603,000 acre-feet scheduled to be released for the month.  On Mondays through Fridays in September, daily release fluctuations due to load following will likely vary between a low of 6,500 cfs (during late evening and early morning off-peak hours) to a high of 12,500 cfs (during daylight and early evening on-peak hours). On Saturdays, release fluctuations will likely vary between a low of 6,500 cfs to a high of 11,500 cfs.  On Sundays, release fluctuations will likely vary between a low of 6,500 cfs to a high of 11,250 cfs.

Releases in October 2007 will likely be similar to September.  The current schedule shows 600,000 acre-feet of release in October 2007, which corresponds to an average flow of 9,800 cfs.

With a lead off quote from Theodore Roosevelt, a legal reply was filed September 4, 2007, by representatives for a coalition of groups challenging the Grand Canyon National Park Colorado River Management Plan.

The Plan was challenged in Federal Court just days after being finalized in March, 2006. The groups challenging the park's commercialized motorized river plan include four nonprofit organizations: River Runners for Wilderness, Rock the Earth, Wilderness Watch, and Living Rivers.
