Factual error: In the scene where Christian Slater and Minnie Driver are trying to get out of the water before it reaches the transformer, there is a real big problem with this scene, if there was a flood and it was rising that high, they city should have shut the electricity in the whole town off to prevent any electric hazards that may happen in that situation.

Factual error: In the scene where the guy gets electrocuted on the antenna, this would not happen. 1)The power would have shorted out long before the water got to the transformer 2) the guy would not have gotten shocked even if the water was electrified because he was not grounded. The water would have taken the electricity to the true earth ground immediately as electricity ALWAYS takes the past of least resistance.

Continuity: Near the end when Karen is handcuffed to the banister, in one shot her hands are handcuffed but not to the banister. This is before Tom shoots the handcuffs to free Karen.

Audio problem: When Jim has been pushed out of the boat by Sheriff in the church, his voice is heard echoing "no" at exactly the same time that he is spitting water out visually.

Continuity: When Christian Slater is in jail, he wakes up to the sound of water. He than swings his legs into the water and stands up. If you look, his pant legs are already wet before he swings his legs off the cot.
