This happened to me about twenty years ago Saralonde. I didn't get hurt jut got a bad cold. As I am a fly fisherman and love fishing Atlantic Salmon I spend a lot of time standing waist deep in streams wearing chest waders. I never went fishing without having my Contax 35mm SLR tucked inside the waders and spent as much time taking pictures as I did fishing. I was taking some shots of a moose drinking at stream side and I slipped. Down I went of course I had to protect the camera and my flyrod so I ended up on my rear both arms up and my waders filling with water. Try standing up when you are wearing chest waders filled with water. Pulled out the line on the rod put it around my arm,(kept the rod safe) then shot ten frames or so of the moose. Sat there in the middle of the stream for an hour or so till my fishing partner came back to meet for shore lunch. Really didn't want to move for fear of being washed down stream.
