Niagara Falls never runs out of water because it’s fed by the Great Lakes, specifically Lake Erie, which holds about 116 cubic miles of water. The falls are part of the Niagara River, which drains Lake Erie into Lake Ontario, moving roughly 28,000 cubic feet of water per second over the falls. The Great Lakes are a massive, interconnected freshwater system, replenished by rainfall, snowmelt, and groundwater across a 200,000-square-mile drainage basin. Even with human water use and evaporation, the inflow from precipitation and tributaries far exceeds what’s lost, maintaining a steady flow. Seasonal variations and upstream ice can reduce the flow slightly, but the sheer volume of the Great Lakes ensures the falls keep running.
