Low head dams may look calm and harmless, but they are one of the most dangerous hazards found on rivers and streams.
The water flowing over a dam creates a powerful circulating current that can trap boats and swimmers underwater. Escape from this current is extremely difficult.
Recognizing the warning signs and avoiding dams can save lives.
If you see a smooth line across the river, you may be approaching a dam.
Always exit the river upstream and carry your boat safely around the hazard before continuing downstream.
Never attempt to paddle over a low dam.
Low head dams create a recirculating current often called a “hydraulic.”
This current can:
• Pull boats and swimmers underwater
• Hold people in a continuous cycle of turbulence
• Prevent escape even for strong swimmers
Because the water often appears calm, many people do not recognize the danger until it is too late.
Follow these simple steps to stay safe on the water.
Check maps and learn where dams are located before launching.
High water and recent rainfall can make river hazards even more dangerous.
More than 80% of boating fatalities occur when someone isn’t wearing a life jacket.
Always exit the river upstream and portage around the hazard.
Extra caution should be used near dams located in:
• Sidney
• Dayton
• Hamilton
• West Carrollton
Watch for warning signs and buoys that mark these hazards.
Free river maps include dam locations, access points, and safety information.
