Since the ground rules don't specifically define the creek as "OB", the player is left to wonder what exactly the special rules are, and when they apply. There's no definition of "island hole" in the rules, right? (Not that that terminology is used on the ground rules, either.)
I think it's pretty clear here, once you see it. Tee shot needs to come to rest beyond the creek, or you re-tee.
