This fellow seems to have a credible background.....having been a 'Dam' inspector.... 😋 His other video about the 4 'tubes' that would come into play below 3490 is also interesting.

Not to 'muddy' the waters, but would love to hear our LP sages thoughts on this......:unsure:

Side note: He does seem to like that suit....even wears it when handling that little outboard......:LOL:

 
This is 100% AI. I don't know why people are making these, but this account has already uploaded 11 videos over the course of less than a month. In every video, he is wearing the same suit and tie and has the standard AI delivery. Honestly, I couldn't listen to the whole thing because that AI speech is too exhausting.

The buildup of sediment really doesn't matter unless you get to the point that you are full again and your maximum capacity is reduced. The idea that you lose a higher percentage of storage at lower levels due to sediment than at higher levels is accurate, but it doesn't really matter at all because you would simply bump the lake elevation to store the water you have available, unless the sediment begins to cover outlet piping, which is not a problem at the elevation of the outlet works for Glen Canyon Dam.
 
Yes, obviously AI, but is the data accurate?
And, as a boater, I’m glad that more sediment makes a higher water level for a given amount of acre feet of water. Provides more navigable water for most of the lake, not so much for Hite.
 
I forced myself to watch this. It's definitely full of AI garbage, but it's also got some information that's accurate, including the general annual sedimentation rate of about 33,000 AFY. One thing the AI engineer didn't speculate on was how far back upstream the sediment stretches, in response to a guess of 4-5 miles from one of the comments to a previous video "he" made. Well, here's the eye-opening answer. At 3520 in 2026, the lake ends just before the Horn. But in the summer of 1965, when the lake first reached 3520, it extended to just beyond the confluence with Dark Canyon, in the lower end of Cataract Canyon. That's about 30 miles upstream from where 3520 reaches today (!). It's the sediment that accounts for the difference.

And no, I'm not AI.

Excellent video thanks for posting it shows the problem is worse that than many think. The good news the recent rains have increased the elevation from the 9/16/2026 low of 3516.62 to 3519.04 on 10/6/2026 2.42 ft

No, pretty sure you are SI. 😉
