Looks like a splice from 06:02:59 to 06:03:10. A couple of the red towers in back change positions. I think this is spliced film, not live.
Very relaxing white noise...
One thing I do not see is any people walking on the top of the dam to monitor things. (Maybe the wouldn’t normally at this hour? Engineers with helmets dressed in white coats?)
Some of the Raised flood gates (?) do not align across the top. It seems like the most turbulence repeats in the same spots below the discharge gates.
