It is separated from the rest of the lake by the Door Peninsula in Wisconsin, the Garden Peninsula in Michigan, and the chain of islands between them, all of which were formed by the Niagara Escarpment. Lake Winnebago, connected to Green Bay by the Fox River, serves as part of the Fox–Wisconsin Waterway and is part of a larger system of lakes ...
Other lakes are found in depressed landforms or along the courses of mature rivers, where a river channel has widened over a basin formed by eroded floodplains and wetlands. Some lakes are found in caverns underground. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice age.

Ancient lake formation is similar to that of a rift valley.Formation occurs within a graben that is located on an active rift zone. Grabens are sections of land, formed along divergent plate boundaries, which have subsided between two parallel plates.
The Finger Lakes region, together with the Genesee Country of Western New York, has been referred to as the burned-over district. [34] There, in the 19th century, the Second Great Awakening was a revival of Christianity; some new religions were also formed. The region was active in reform and utopian movements.
Melting glaciers formed many of the state's lakes and etched its river valleys. They also formed a number of proglacial lakes, which contributed to the state's topography and soils. Principal among these lakes was Lake Agassiz, a massive lake with a volume rivaling that of all the present Great Lakes combined.
The proglacial lakes of Minnesota were lakes created in what is now the U.S. state of Minnesota in central North America in the waning years of the last glacial period. As the Laurentide Ice Sheet decayed at the end of the Wisconsin glaciation, lakes were created in depressions or behind moraines left by the glaciers.
The Lockhart Phase is associated with the Herman lake stage (335 metres (1,099 ft)), the highest shoreline of Lake Agassiz. The Big Stone Moraine formed the southern boundary of the lake. During the Lockhart Phase the lake is estimated to have been 231 metres (758 ft) deep, with greater depths near the glacier.
