Flood: A River's Rampage (1997)

Sinopsis

After heavy rain, the Mississippi is breaking it's banks flooding small towns. Richard Thomas and Kate Vernon realise their town is next on the hit list. Lots and lots of sand bags might not do the trick but a huge explosion might. In the meantime the plot is filled up with a predictable story about a family dreading their mistake of staying behind when they become entrapped in their own home.
