Believe it or not you could get lucky. I would remove the batteries and rinse it well with distilled water, Shake out the excess and dry either with a low heat from a blow dryer at distance or immerse in a bag of rice for a few days. The key is get out the conductive salt water residue. My cottage customers are always dropping things in the lake and we use the rinse and rice routine with good results. But fresh water is more forgiving and salt water is corrosive. Hey you never know. Good luck.
if the lens has been flooded and has salt stains on it, it would be extremely hard to soak that kind of stuff out and leave all the surfaces of the lens spot free so that the pictures not be effected.
