Don`t Let Rivers Fool You!
- Water flows much faster and deeper a short distance from shore.
- Cold water and swift current can overpower any swimmer.
- Hazards like submerged trees can trap you under the surface.
Make river visits safer by following these guidelines:
- Wear a life jacket for all river activities.
- Find areas with very slow moving water.
- Avoid entering fast moving water, even if it seems shallow.
