Josh 3:15-16
15 When the priests got to the Jordan and their feet touched the water at the edge (the Jordan overflows its banks throughout the harvest), 16 the flow of water stopped. It piled up in a heap — a long way off — at Adam, which is near Zarethan. The river went dry all the way down to the Arabah Sea (the Salt Sea). And the people crossed, facing Jericho.

This same thing happened to the Red Sea!
