Falling in in your waders

Yesterday a 17 year old duck hunter drowned in lake seminole, coincidentally where we are headed tomorrow. He and two classmates were hunting and capsized and sank their boat, the other two boys made it out alive but the one guy lost his life, thoughts and prayers for his friends and family and the two boys who are in the hospital. The article can be found here.

Seminole is full of stumps and gators and has always been a dangerous spot, there have been quite a few duck hunters go over the dam, one guy was never found, we will be very careful out there this weekend.
So, with this being said, what do you do if you fall in? I know guys who don't put their waders on til they get to their hunting spot, which seems to be the most logical answer to this, but it's not always the case. What I've read is if you do happen to come in to this situation is not to panic, that's what causes you to go down.
A buddy of mines little brother told me that he tested it out in the swimming pool once and that his waders floated. Any input?
