How we ranked these

The order is each lake's total surface area in square miles. The Great Lakes are counted at their full size even though they are shared with Canada. Lake areas are standard published figures; levels and shorelines change with the seasons, so check local sources before a trip.

Questions people ask

What is the largest lake in the US?

Lake Superior, at 31,700 square miles. It is shared with Canada.

What is the largest lake entirely in the US?

Lake Michigan, at 22,300 square miles. It is the only Great Lake that lies completely within the United States.

What is the largest lake outside the Great Lakes?

Lake of the Woods, at 1,679 square miles, shared by Minnesota, Ontario and Manitoba. The largest lake entirely inside one state is Iliamna Lake in Alaska, at 1,014 square miles.

Why does the size of Great Salt Lake change?

It has no outlet, so its area rises and falls with rainfall, snowmelt and water use. The 950-square-mile figure is a typical area, not a fixed one.

Are reservoirs counted?

Yes. Lake Oahe on the Missouri River is a reservoir created by a dam, and it makes the top ten by area.
