Elk, I'm not sure that was really good advice.

If your feet are pointed upstream, your head is pointed downstream. As such, it or your neck or back will be the first thing to ram into any rocks as you are swept downsteam.

I'd far rather deal with the situation with water in my waders than while unconscious or paralyzed.

For me it is FD3:

FD1=Feet downstream ASAP.

D2= Drop your rod if you can't swim with it well enough to get to shore fast. Ain't a rod made that is worth more than my life.

D3=drop the tops of you waders as you reach shore. Water doesn't weigh more than water so you waders won't drage you down while you are swimming. But water weighs a whole lot more than air and will keep you from climbing out when you reach the shallows and don't let the water out of your waders.

Just one person's opinion so don't sue me if you drown by following this approach!
