I was over at the MK on 7/12 and I noticed IASW was having some water flow problems in some of the scenes.
In this picture, you can obviously see the trough that guides the boats. That is normally underwater and is not seen by guests.
You can also kind of see the line that water has left on the facade near the Unload area:
There are more pics of the park in general at http://reachforthemagic.proboards.co...read=21&page=1
