There is no real reference as to the purpose of the dam. There is only a mention of hydroelectric power, but no mention of why this was needed. Most of the article concentrates on the controversy and negative repercussions of the damming, which is not a bad thing (I think it is quite a good thing to include in this article), however, more needs to be included as to the reason the dam was built and its history/uses. (Note: If I've erred in posting this someway, please correct me, this is my first contribution/post to the Wikipedia.)- Tuxley, Dec. 5, 2005, 5:31 AM EST
This needs text, not just collection of images. I have only vague memories of reading Edward Abbey, and don't think that's a good basis for my writing this. Vicki Rosenzweig 16:39, 19 Oct 2003 (UTC)
What's so "radical" about the Sierra Club? The wikipedia's own article about that group doesn't characterize them in that manner. There's no reason to paint them with the same broad brush as Earth First! or to revert the deletion of that word.
I believe that the reference to experimental flows in 2005 is incorrect, the last experiment was in 2004. Also, the reference to excess silt being flushed into Lake Mead is odd given that all sediment introduced into the mainstem below GCD will eventually be washed into Lake Mead, and the quanitity of sediment in the system is a fraction of what occured prior to the completion of the Dam. If this article is going to reference the post-dam environmental efforts, it should start with a link to the Grand Canyon Adaptive Management Program - http://www.usbr.gov/uc/rm/amp/index.html - and the Grand Canyon Monitoring and Research Center - http://www.gcmrc.gov/gcmrc.htm
This page is for display worldwide, and more than half the world uses the metric system. Anyone on that?
Wouldn't it be proper to add a section in the environmental section describing the amount of greenhouse gases that are not pumped into the atmosphere as a result of the electricity produced by the dam rather than through a fossil burning power plant? —Preceding unsigned comment added by 67.50.43.10 ( talk) 08:54, 21 November 2007 (UTC)
I would question the neutrality of the environmental impacts section. There is nary a word for the positive changes to the Grand Canyon because of the cooler, cleaner water coming from the dam. A reference to a dam support website, such as friends of Lake Powell would provide a more balanced entry. After all it is an opinion that native environment is better than non-native environment.

I removed the following text from the article:
While technically true, I think this statement is misleading. The CRSP includes only dams on the upper Colorado River, and Glen Canyon is the last dam in the project. In particular, Hoover Dam is not part of the CRSP, and Lake Mead holds more water than Lake Powell. Links:

The extra quote of the Sierra Club leader adds a biased tone to the history section. I vote to remove it to maintain the balance between the regret of the environmentalists/dam opponents and the satisfaction of the recreationalists/hydroenergists/dam supporters.

"Route 66" is referred to as a "cult classic." What "cult," beautiful Corvettes and open America? The article could be improved by deleting the word "cult." — Preceding unsigned comment added by 216.49.20.187 ( talk) 22:43, 28 April 2014 (UTC)
I have seen reports that the dams support (physical that is) has been eroded. From what I heard, the dam was built on a porous stone that has allowed water past the dam. That should be addressed in the article. Will ( Talk - contribs) 17:13, 31 October 2008 (UTC)
Later History section: The first sentence in the 1983 floods and legacy subsection, "During the first half of 1983, a deep snowpack in the Colorado River headwaters, heavy spring rain and a rapid rise in temperatures that precipitated swift snowmelt combined to create perfect conditions for maximum runoff on the Colorado River.", could be better presented thereby shortening the run-on sentence. There is no need for a comma after a year (1983) and serial comma's have a purpose.
"Design Structure and storage" "were used for flood purposes only once in 1983" If I read the text above it states that the following year on august 12th 1984 they had to open the flood gates again. they are also used for assisting the recovery of the damaged riverine ecosystem 1996 2004 2008 2012
The next paragraph needs to be rewritten the math does not compute probably originally eight 155,500 horsepower aka 119MW generators totally more or less 930MW upgraded to 5 * 165MW + 3* 157MW totaling 1296MW — Preceding unsigned comment added by 71.13.171.178 ( talk) 21:53, 18 September 2015 (UTC)
Good day, over the next couple of days I will be working on the article because I believe it can achieve "Good Article" status. I hope we can achieve this as a team. AmericanAir88 ( talk) 03:11, 9 November 2017 (UTC)
Hey folks, in some research I am doing, Sec of Interior Seaton poured the first concrete June 17, 1960. Can anyone state the reasoning for the June 16 date? Cordially yours, Tom (Cite "Dam Concretre Pour Needs 1,275 Men by Year's End," Arizona Daily Sun, June 17, 1960; "First Concrete Poured at Glen Canyon Dam, Arizona Daily Star, June 18, 1960 RRFWTommartin ( talk) 23:01, 14 June 2021 (UTC)
I noticed that the conversion template is inaccurate. Can someone explain why it is not converting 710 feet to 216 meters? The same thing occurs in the List of tallest dams in the United States article. Xnatedawgx ( talk) 03:33, 9 July 2023 (UTC)
