MINNESOTA - In the "Land of 10,000 Lakes," the competition for the title of "largest" is surprisingly complex. Minnesota's landscape is a patchwork of glacial basins, and while several massive bodies of water border the state, the titles for the largest inland, natural, and artificial lakes are held by distinct and legendary waters.
The Border Giant: Lake Superior
If you count every drop of water within state lines, Lake Superior is the clear winner. As the largest freshwater lake in the world by surface area, it is oceanic in scale.
- Surface Area in MN: Approximately 962,700 acres (out of 20 million total acres).
- Maximum Depth: 1,333 feet.
- Location: Bordering the northeastern "North Shore" of Minnesota.
Lake Superior shapes the region's culture, from the busy international port of Duluth to the rugged, cobblestone beaches of Grand Marais. Its water is famously cold and crystal clear, and its "inland sea" status means it can produce waves over 20 feet high during the notorious "Gales of November."
The Inland Champion: Red Lake
When looking for the largest lake located entirely within Minnesota's borders, Red Lake stands alone. This massive body of water is so large that it is divided into two distinct basins: Upper Red Lake and Lower Red Lake.
- Surface Area: Approximately 288,800 acres (about 450 square miles).
- Location: Beltrami County in northern Minnesota.
Red Lake is a vital cultural and economic hub for the Red Lake Nation. While Lower Red Lake and much of Upper Red Lake are closed to the general public to protect tribal fishing rights, a portion of the Upper Red Lake is a premier destination for walleye and northern pike fishing. The lake is relatively shallow for its size, which contributes to its status as one of the most productive fisheries in the state.
The Man-Made Leader: Rainy Lake
While Minnesota is famous for its natural glacial lakes, it also features significant artificial reservoirs. Rainy Lake is often cited as the State largest artificial lake because its natural size was dramatically increased by the construction of the International Falls Dam in 1909.
- Surface Area: Approximately 230,000 acres (roughly 70,000 of which are in Minnesota).
- Location: On the Canadian border, serving as the gateway to Voyageurs National Park.
Rainy Lake is a labyrinth of over 2,000 islands and rocky channels. Because the dam regulated the water levels to power the local paper mills, it transformed the watershed into a massive, navigable reservoir. It offers a true "Northwoods" experience, where boat-in camping and houseboating are the primary ways to explore the pristine wilderness.
Minnesota's vast water network is led by Lake Superior, a global giant that provides nearly a million acres of water to the State North Shore. Red Lake is the largest internal body of water, serving as a massive, natural stronghold for the Red Lake Nation and local anglers. Meanwhile, Rainy Lake represents the State largest artificial reservoir, a sprawling, island-filled border water that anchors the remote beauty of Voyageurs National Park.
