The Niagara River flows north from Lake Erie to Lake Ontario, forming part of the border between Ontario, Canada, to the west, and New York, United States, to the east. The origin of the river's name is debated. Iroquoian scholar Bruce Trigger suggests it is derived from a branch of the local Neutral Confederacy, referred to as the Niagagarega people on several late-17th-century French maps. George R. Stewart posits that it comes from an Iroquois town named Ongniaahra, meaning "point of land cut in two."

It narrows in the Niagara Gorge, where two hydropower reservoirs are visible, and then widens after exiting the gorge. The Welland Canal is visible on the far left.

Lake Erie is the fourth-largest lake by surface area of the five Great Lakes in North America and the eleventh-largest globally. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and also has the shortest average water residence time. At its deepest point Lake Erie is 210 feet (64 m) deep, making it the only Great Lake whose deepest point is above sea level.
