• Horseshoe Falls (Canadian Falls): 57 m (187 ft) high, 790 m (2,590 ft) wide; most powerful in North America.
• American Falls: 21‑34 m (70‑110 ft) high, 320 m (1,050 ft) wide.
• Bridal Veil Falls: Smaller, adjacent to American Falls.

Combined flow exceeds 6 million cubic feet per second (168,000 m³/s) at peak. The falls are a major hydroelectric source and world‑renowned tourist destination.
