This is quickly becoming my favorite thing about GCA. What a great exercise. And after great study, my opinion is...leave it where it is originally. Here's why I think that is the best place:
--First picture at first glance I liked best (pond in front). Here the hazard protects the green the most and will play a part in the golfer's thinking no matter where the hole is. But, I bet it is out of sorts with the rest of the golf course and it takes the run up option out of play. And the visual is not great; looks like a big bath tub plunked in front of the green. But in terms of most effect on the second shot, I like it here the best. But its out.
--Second picture (pond on the left) just doesn't do much for me. So there is a pond over there, so what. It doesn't protect the green much, if at all. It may reward the tighter line off the tee(only because it doesn't penalize it), but it doesn't penalize the tee ball played much further left. From that side of the fairway the player, on all shots except the far left hole location, is actually playing away from the water. So its out.
--Third picture (pond on right) is probably the most visually appealing look. But it actually penalizes the more risky drive played close to the bunkers, making that play foolish unless the pin is back left. So its out.
--Which makes me think why have the pond on the hole in the first place? The part of the green in pics 2 and 3 it guards is already being guarded by bunkers. Leave them to do their job. The hole would be best served by having no pond, so take it out. Unless Jeff is correct and it needs to be there for drainage. So leave it where it is.
Please Ian, keep em coming!
