Video of Demopolis Lock filling it's chamber with water so a boat can be locked going upstream. These whirlpools are formed on the river that runs near Demopolis, Alabama. These are NOT naturally occurring whirlpools and instead occur because large pipes under the water suck water into the area behind me (not seen in video until I turn to walk off the bridge/platform area, it's the place to the left) and fill it with water so boats can easily navigate the river without having to load/unload boats onto higher/lower areas all the time.
I wanted to record the entirety of this video because I never knew what a whirlpool looked like when it was forming. Honestly, I think that's the most interesting part - not the fact that they are A) So big B) TWO of them and C) THEY ARE SPINNING OPPOSITE DIRECTIONS. :D
This video is meant for educational purposes. Teachers: Go ahead, use it in class. I know I've already had a couple of my high school teachers want to show it in class and I gave them the go ahead. I'd prefer if people not to reproduce this video content unless they are making an educational video in which this is being used as an example.
Have fun guys and gals, and I hope that this is a better description than was here before.
