Ledge Hole on teh Mama Chama Section
There were two bad swims involving AWC members on the Mama Chama section 2017 when we ran it at flows over 1500 CFS. It was the same ledge hole that caused both swims.
It is located well past the fisherman's bridge near the start of the El Vado lake bed. By that point you think you are done with the rapids and you would not expect anything so heinous of a river feature.
I consider it a class IV hazard in what is otherwise class II+ or maybe class -III water even through the Mama Chama rapid. It is a potentially deadly keeper hole. You can dodge it, but it is hard to spot for anyone without class IV+ experience, especially if they aren't expecting it.
This year snowpack suggests it will hit high flows again so I want to get this warning out in the hopes of avoiding potential tragedy.
Swift water rescue skills were essential in the two swims that occurred during the last high water flow in 2017.
Thanks for your time and attention and happy boating!
