<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).

Laminar / Helical Flow<br />

• Water along the shore and<br />

bottom are slowed by friction,<br />

the water moves faster<br />

towards the center of the<br />

waterway<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
