The water does flow out of Glen Canyon Dam clear and green. But it is still fairly rare to see the Colorado River looking green as it does farther downstream in Goldmember's pictures. Rain on the plateaus high above the river flushes more mud down through the many streams and rivers that enter the Colorado downstream from the Dam--particularly the Little Colorado River--typically turning the green water from the Dam back into the chocolate-milk-like flowing mud you see in most pictures of the River.

 

Best regards,

I'm not sure about that- Google image search shows quite a lot of green... https://www.google.com/search?q=Grand+Canyon+colorado+river&source=lnms&tbm=isch&sa=X&ei=N3SbU9TdEsKSyATXuoLYBg&ved=0CAYQ_AUoAQ&biw=973&bih=762

 

Contrast with a search for Cataract Canyon flowing into Lake Powell... https://www.google.com/search?q=Grand+Canyon+colorado+river&source=lnms&tbm=isch&sa=X&ei=N3SbU9TdEsKSyATXuoLYBg&ved=0CAYQ_AUoAQ&biw=973&bih=762#q=cataract+canyon&tbm=isch

 

Upstream silt capture was a side benefit, but the key reason Lake Powell exists is to allow states on the upper Colorado River to pull out water upstream while maintaining their contractually mandated flows to the lower river states per the Colorado River Compact. Before the dam, upper states had no good way to retain water for their use while still delivering water to AZ, NV, CA. Very little water gets pulled from Lake Powell, it just gets parked there in an incredibly hot place to evaporate ridiculous amounts of it away, just to satisfy terms of an agreement that assumed far more river flow than really exists...  Of course, the crazy idea of having water sit for years in a desert just to have a sizable chunk of it evaporate away also holds for Mead, but at least Las Vegas actually pulls water out of Mead...

 

The dividing line between upper and lower is Lees Ferry just below Glen Canyon Dam, one of the big (but not only) reasons Lake Powell happens to be where it is.

Terrific pics GoldMember....our time on the planet is pretty insignificant to what one sees there.

Thanks! Yes, we're insignificant specks on the overall time spectrum.

One of the things I'd like to comment on here and in our own trip report is this...

The National Parks, including the Grand Canyon, are an incredible bargain in comparison to what you get out of them.  Heck, they are a bargain no matter what you get out of it. 

 

We paid 25.00/car for a pass to the South Rim.  The pass was good for 7 days. 

Of course there are free pass for active military, senior rates, etc.....

 

Tell me where you can get 7 days of access to anything as amazing as this for this price.  Other National Park prices can vary, but still......

We are truly fortunate to have this greatness available for such a bargain.

Indeed. Ken Burns was right; it's America's Best Idea.

 

Went to Yosemite for it's 150 year anniversary. Still as majestic as the first time I saw it, albeit a lot more crowded and a lot drier.

 

With miles of backcountry and jaw dropping vistas, the national parks provide people with unique opportunities to be in nature that most would not otherwise have, even for those who are elderly or have disabilities. Also, there is an amazing network of National Wildlife Refuges when you've done all the parks...;-)
