I didn't realize the game lacking a water region until very recently, when I was going over the game again, just before my boss battle. I was disappointed, because although Lake Floria was kind of like a water temple, it didn't have the puzzle elements, or the big exploration, or the need to get to the temple before you started it. It was just like, you were in the forest, then it all of a sudden turns to water. Lake Floria wasn't so much of a satisfying temple either, I would definitely say that it wasn't as good as some of the other ones.
So, in short, yes, I was indeed disappointed.
