Although the water around dams may look peaceful and inviting,
it is very dangerous!!
When water drops over a dam, a condition known as a "hydraulic roller" occurs. When a person or an object, such as a boat, gets caught in this roller, it is almost impossible to get out.
** They are often hard to see, especially from the upstream side.
Small dams are especially dangerous! Why?
** They don't look dangerous, so people often get too close.
