Lake Ontario

One of North America's five Great Lakes is Lake Ontario. The U.S. state of New York, whose water boundaries along the international border meet in the center of the lake, borders it on the south and east. Ontario, a province in Canada, is its neighbor to the north, west, and southwest.

The northern and western shores of the lake are occupied by the Canadian cities of Toronto, Kingston, Mississauga, and Hamilton, while the southern coast is home to the American city of Rochester. Ontario means "big lake" in the Huron language. The Niagara River, which flows into Lake Erie, is its main inlet. The eastern end of the Saint Lawrence Seaway connects Lake Ontario, the last of the Great Lakes, to the Atlantic Ocean. This exit is made possible by the Saint Lawrence River. The Moses-Saunders Power Dam controls the lake's water level.

Lake Ontario is an ecological marvel because of its size and proximity to the Atlantic Ocean. This lake serves as the conduit for the Great Lakes' entire water supply. Fish move from the ocean to the freshwater lake repeatedly. The lake's various regions offer a variety of environments, including dunes, wetlands, forests, and rocky cliffs.

Location: on the north, west, and southwest by the Canadian province of Ontario, and on the south and east by the U.S. state of New York
