Continuity mistake: When Jake goes into the water with the tow rope around his waist, the rope is going over the top and through the railing of the boat. When he gets pulled away with the girl, the rope is seen down in the water.
Continuity mistake: The cliffdivers' shorts change from blue to white.
Continuity mistake: When Novak hops in the boat to join the sheriff as she races off to rescue her children, he is wearing shoes/boots. Later, when they are pulling Jake and Kelly out of the water, Novak is barefoot.
Continuity mistake: The length of the rescue rope changes drastically.
Continuity mistake: The little girl steps on glass. Later in the movie when they are climbing across the rope, there's no cut on her foot.
Continuity mistake: At the beginning of the movie, when the sheriff falls into the pond reaching for the boat, she comes out dragging the body but is not wet at all. I guess being in "Back to the Future Part 2" helped her get the self-drying clothes.
