<strong>Swiftwater</strong> <strong>Review</strong><br />
• Water flow travels between 5 and 45 mph.<br />
• The Flood Control System crosses many<br />
jurisdictional boundaries.<br />
• <strong>Swiftwater</strong> Rescue is dynamic. Training must be<br />
continuous to maintain safety (rescuer and<br />
victims).

the water moves faster<br />
towards the center of the<br />

Low Head Dams<br />
• When water flows over, or passes a<br />
vertical drop or obstacles, a hydraulic<br />
effect is created.<br />
• Low-head dams are a type of hydraulic<br />
and are dangerous areas for rescue.<br />
• We operate no closer than 300 feet from<br />
low head dams
