Other mistake: When Data discovers the holoship in the lake he reduces the amount of water in the lake significantly (The ship is now clearly visible, standing out several meters). But even so the banks and the landing stage are still in their correct position. If the surface level had been reduced the landing stage should have been standing out of the water, too.
Revealing mistake: When the Bak'u are fleeing, and running across the bridge, you can briefly see the launchers that are used to propel the stunt people into the air.
Trivia: There is a scene in the film where Baku people are running to the caves, or something like that. In the original cut of the film, some actors where chewing gum. The director and producer decided it didn't make them look scared, so they filmed than shot again, and it cost about one hundred thousand dollars.
