Lake, in U.S. and Canada.
The fourth largest of the five Great Lakes , it lies between lakes Huron and Ontario and forms the boundary between Canada (Ontario) and the U.S. (Michigan, Ohio, Pennsylvania, and New York). It is 240 mi (388 km) long and has a maximum width of 57 mi (92 km), with a surface area of 9,910 sq mi (22,666 sq km). The Detroit River carries inflow from Lake Huron to the west, and the lake discharges at its eastern end through the Niagara River . It is an important link in the St. Lawrence Seaway ; its ports handle steel, iron ore, coal, and grain. The area was once inhabited by Erie Indians; when the French arrived in the 17th century they found the Iroquois living there. The British were in the region in the 18th century, and the U.S. shores were settled after 1796. It was the site of the Battle of Lake Erie, an important engagement of the War of 1812 .
