Though doing more I think I discovered why I see a difference. If you use maps.google.com/maps and are not signed in to a gmail account you can see typhoon lagoon drained but if you are using maps.google.com/preview and are signed in to a gmail account then you see what I have posted.
For me, I see a filled Typhoon Lagoon no matter what I do when viewing on Chrome. But when viewing on Safari, I see it empty if I look at it in the 45-degree view and full when looking straight down on it.
