Why Small Waterfalls Can Trap Swimmers

Small waterfalls can be far more dangerous than they look. When water drops over a ledge it can form a circulating current known as a hydraulic. This current pulls water back toward the waterfall creating a loop that can trap swimmers, boats, or debris. Even a life jacket may not help because the current keeps dragging the person back toward the drop. Rescue teams often train using controlled setups like this to demonstrate how powerful these currents can be.
