It was a saying commonly said at church, when one member would ask another if they would be there on the following Sunday. They would respond, "Lord willing and the Creek don't rise." This has nothing to do with the actual body of water. You see, this was set back in the days of the Creek Indians. The [European invaders]Settlers were afraid that the Creek would rise up and retaliate against the settlers for invading their land. Hence, the saying, "Lord willing and the Creek don't rise!"
