• Class 1: Very small rough areas, requires no maneuvering. (Skill Level: None)
• Class 2: Some rough water, maybe some rocks, small drops, might require maneuvering. (Skill Level: Basic Paddling Skill)
• Class 3: Whitewater, medium waves, maybe a 3-5 ft drop, but not much considerable danger. May require significant maneuvering. (Skill Level: Experienced paddling skills)
• Class 4: Whitewater, large waves, rocks, maybe a considerable drop, sharp maneuvers may be needed. (Skill Level: Whitewater Experience)

• Class 5: Whitewater, large waves, large rocks and hazards, maybe a large drop, precise maneuvering (Skill Level: Advanced Whitewater Experience)

• Class 6: Whitewater, typically with huge waves, huge rocks and hazards, huge drops, but sometimes labeled thusly due to largely invisible dangers (i.e., a smooth slide that creates a near-perfect, almost inescapable, hydraulic, as at Woodall Shoals/Chattooga). Class 6 rapids are considered hazardous even for expert paddlers using state-of-the-art equipment, and come with the warning "danger to life or limb." (Skill Level: Expert)
