Question: What is the U.S. state with the longest freshwater coastline?
Show answer
Michigan.
The U.S. state with the longest freshwater coastline is Michigan. This is due to the state’s unique geography, being composed of two peninsulas that are surrounded by the Great Lakes. These bodies of water include Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. The total length of Michigan’s freshwater coastline, including islands, is over 3,000 miles long. This gives Michigan more coastline than any other state except Alaska, which has the longest coastline including saltwater coastlines.
