but an excellent explanation. Interesting how the hydraulics change with different water levels upstream and downstream. There are so many dams around here that I just stay away from all of them. Thanks for posting - good reminder.

too bad people who need to listen to it - recreational kayakers without any idea as to what it is they are doing - never will see it (or have the patience to sit though 20 minutes of "boring technocal scaremongering")
very good video and explanation ........|

For a while I worked as a family doc in Montana. Had a lovely couple as patients and delivered their baby. Two weeks later he went over a diversion dam in a canoe and got caught in the rebar at the bottom of a hydraulic, drowned. I still remember the horror and sadness...

several of these in our area that I intended to run... not knowing the danger. In fact, there's a lot of things I've learned here that have saved me much time, money and very possibly, my life.
