United States: water area 2018, by state or territory
Alaska, the largest state, has the largest water area by a significant margin, at almost 95,000 square miles (35 percent of the country's total). This is followed by Michigan, which has over 40,000 square miles of water area - the majority of this comes form the Great Lakes, as large shares of Lake Huron, Lake Michigan, and Lake Superior fall within Michigan's boundaries.
