Niagara Falls Coordinates: Three Falls, Three Locations

Niagara Falls isn't a point—it's three distinct waterfalls straddling the US-Canada border, each with its own coordinates.

Precise Coordinates (WGS84)

Key Reference Points

• International Boundary: Runs through Horseshoe Falls (mostly Canada) and between American/Bridal Veil (US).
• Niagara River: Flows north from Lake Erie → Falls → Lake Ontario.
• Cities: Niagara Falls, ON (Canada) / Niagara Falls, NY (USA) — distinct municipalities.

Dynamic Geometry

Erosion retreats falls ~0.3 m/yr (historically 1-1.5 m/yr pre-diversion). Coordinates shift. Horseshoe Falls migrating upstream faster than American Falls. Future: possible merger or separation.

Measurement Context

GPS accuracy: ±3-5m (consumer), ±1cm (survey). USGS/NGS benchmarks on both sides. Coordinates above are consensus values from USGS, NRCAN, and NYS GIS.

Three falls, three coordinates, one thunderous system.
