I don't see the utility of a provisional ball in this case. If you hit a provisional, and get to the lake and don't see the ball, where are you? Was the ball lost in the hazard, or elsewhere? If it is decided that it's KVC that the ball is in the hazard, you may take the appropriate relief, which includes going back to the tee, but the provisional that you already hit is NOT usable for that purpose. Only if you decide that it is not KVC that the ball is in the hazard may you play the provisional. I could see the position of the provisional ball influencing one's opinion of whether the ball is in the hazard or not, which is not a good thing.
Given the description given, I think that it is KVC that the ball is in the hazard, when the question "could it be anywhere else?" is asked, it seems the answer is no. More trees, thicker grass, leaves on the ground, etc., would change that opinion.
To get back to the original question, it isn't necessary for anyone to see the ball enter the hazard. I'm sure we have all played holes where the ball can get into a hazard without the entry being seen, but no doubt as to it being in the hazard. A gentle slope into a pond, for example, closely mown, with no place for the ball to hide. That takes C's original statement right out, as does the decision quoted above.
