Lake Powell Glen Canyon Dam High Flow Experiment 2023 Before and After

Published 2023-05-05
This video will show the before and after of the Colorado River prior to the High Flow Experiment of 2023. This video explains the data provided by the Bureau Of Reclamation and the USGS. You will see new sand bars the river has created during peak flow of 39,000 ft.³ per second. Also an explanation of sediment and how it is measured. Scenic views of the Vermilion Cliffs, Echo, Cliffs, Lees ferry in the Paria beach. Information will be provided in this bio.

    Filming this must have involved a lot of hiking and here I am watching it for free.
  • @markcarey8374
    Thanks for the visual! You did a lot of walking for this one,Thanks for the history!! ✌️
  • Amazing video! Love the drone shots and the old footage you have shown. Thanks for taking the time to make this!
  • I was on the atkins trip when this took place. Lee’s ferry to Pearce ferry(21 days)
  • @gup8175
    Great video! So good to see the cottonwood trees planted there.

    Nice one, Ratty. I always enjoy your videos. As you say, these HFEs just release sediment-free water downstream to rearrange what little deposits there are in Glen and Grand Canyons. Meanwhile, for the last sixty years, the trillions of tons of crap, so vital to the Colorados ecosystem, have been settling out miles away in the Hite area and up the San Juan etc. At the mouth of White Canyon the sediment is over 140ft deep. The river continues to carve down through this stuff (your Hite video suggests the cliffs of mud stand 30-40 feet above the river) which just sends it further downstream. The next time Powell gets extremely low, the river delta could well appear in the Good Hope Bay area. These HFEs are worthy but ultimately futile. Keep up the good work, sir.

    This took some time and effort. Very nice job it's amazing the difference .I love the Before & After's. exciting Video. Hey why is the water so green it almost looks like the Chicago river on Saint Patrick's day. thanks for a great video.😎
  • From NZ. Amazing video. thank you for your work. As the first of the two major dams Lake Powell must be accumulating an extremely large amount of sediment. even in NZ we have some major water issues.
  • @AlanzFPV
    Great job on this. I look forward to these videos
  • Excellent series of videos-thx from an Az transplant to Seattle-Cheers!
  • @lrx54
    Looks good! They should do this every spring

    When you go down into the Grand Canyon and see the river and the cliffs and the overall size and scale . . . you can sense the passage of Time . . . you feel small . . . and come out a different person.
  • The experiment came about from a mud trout that thrived in the muddy Colorado River that went extinct in the clear water . They tried too reinduce the fish cant remember the proper name of the fish.This video was great explanation of what is going on with the releases
  • So, are they able to get above damn sediment to pass through? Must be a tonne of sediment settling before it…?!?
