One night, in very early spring, a local man noticed that things were a bit quiet in his neck of the woods. Too quiet! He walked in the direction of the loudest thing in town – the falls. When he arrived, he saw that the river had been reduced to a low trickle. By morning, people woke to see that the entire Falls had run dry. People’s reactions were mixed. Some were sure it was a sign of the end of the world.
