Lake Ontario - February 16th, 2009

Lake Ontario is one of the five Great Lakes of North America. The lake is bounded on the north by the Canadian province of Ontario and on the south by Ontario’s Niagara Peninsula and by the U.S. state of New York. It is the smallest of the Great Lakes and the only one that does not border with Michigan.

Lake Ontario is the smallest in surface area (7,540 square miles, 19,529 km²) of the Great Lakes, although it exceeds Lake Erie in volume (393 cubic miles, 1639 km³). It is the 14th largest lake in the world and has a shoreline 712 miles (1146 km) long.

Lake Ontario has an elevation of 246 feet (75 m) above sea level. Its length is 193 miles (311 km), and its width is 53 miles (85 km). The average depth is 283 feet (86 m), with a maximum depth of 802 feet (244 m).

The portion of the lake visible here is the extreme eastern shore, in the United States, including Chaumont Bay, Black River Bay, and Henderson Bay.

The United States’ shore of the lake is largely rural, as can be seen from the few white dots showing the presence of towns.

Because of its great depth, the entire lake rarely freezes in winter. During the winter months, the lake typically develops an ice sheet covering between 10% and 90% of the lake area depending on the severity of the winter.

As this image exemplifies, ice sheets typically form along the shoreline and in slack water bays, where the lake is not as deep.
