Heh, correct me if I'm wrong but this bug occurs because:
On each continent the water level is set at a certain height, so if the terrain *ever* goes beneath that level water will show up. This can be prevented in certain areas I assume because as we all know, in general the huge underground base areas aren't flooded, plus a few (I think) pits in the terrain don't have water either. Somehow in some towers and possibly bases the water blocking is broken slightly so if you look at it from a certain angle the water shows up.
So assuming my above explaination is correct then all you have to do is find a tower that goes beneath the sea level, mess around for a bit and you'll see the water. I've come across this bug many times myself and each time I've checked the tower is beneath sea level. Any PS devs feel free to come in and totally smash apart my theory :P
