Courage The Cowardly Dog

The goat never explains what happened to the water! He says the humans "used it up," but how could they use it up enough to the point of there being no water there? And there must have been some water left when the goat drove them away. (Or why would they still have been there?) It's true that the goat never explained what happened to the water, but the audience can guess what happened. Near the end of the episode, when the goat pushes Courage down from the top of the mountain, he holds on to a bottle that's jammed into the rocks. When he falls holding the bottle, water pours from the hole. Apparently, when the humans came, they littered, and the bottle jammed the hole. The goat probably didn't realize this, and that's why he says they "used it up".
