well it is very nice sad to see your camera go into the river just had a flash my only flash fall into the Mississippi river but sadly no photo to show for its death. love the B&W great depth makes me feel cold
Make sure you keep it in a warm/hot environment (like a heated room with a fan on it) so none of internal water can rust away at the cameras internal components.
I think it was 2005 when I got caught in a torrential downpour in the rain forests of Costa Rica and one of my 20Ds got soaked. The inside of the LCD was fogged up for at least a week. It's still going strong today (knock on wood).
