My suggested icon would be a triangle with water squirting out. Unfortunately, I don't have the design skills to draw such an icon.

In my area all water parks are mapped with leisure=park instead of leisure=water_park. This is mapping for the renderer.

Because leisure=park is looking good (see water_park.gif) and you can see that it is a water park because of the swimming pools, I wouldn't use different colors or an additional icon. Just render leise=water_park the same as leise=park, so we can fix the "mapping for the renderer" issue.
