There is a par-3 hole at The Hills (NZ) with a canal / drainage ditch running beside the green, except it's several feet higher than the green or the tee. I think it's the 16th.
Some of the oddest stuff I saw this year was in Kenya, at a course called Vetlab [which is also an odd name: the course is attached to a small veterinary college]. One hole had an elevated tee hitting through a chute, and about 100 yards in front of the tee, at the bottom of the hill, was a large tree rising up and blocking most of the landing area, that you had to hit over . . . if you tried to play either side of it you would probably wind up in the trees lining the fairway. There was also a crazy wild green on a par-4, that would have been neat to study, except the green was also right in the line of second shots cutting the corner of a par-5 that played up and around the green in question . . .
