Glacial moraine could dam and prevent glacial meltwater from escaping. Glacial lakes usually form behind the moraine as the thawing glacier retreats.
A glacial lake is a lake with origins in a melted glacier. Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks.
Glacial spillways are formed when meltwater from a retreating glacier creates a pathway through moraines or other glacial deposits. As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.
glacial lakes. These lakes were formed by the meltwater from the ice blocks, and often occupied depressions in the landscape created by glacial activity. They were temporary features that eventually drained as the ice melted away completely.

Glacial Lakes State Park was created in 1963.

Lakes Superior, Michigan, Huron, Erie, and Ontario.
The name given to lakes formed through glacial erosion is "glacial lakes." These lakes are created when glaciers carve out depressions in the land, which then fill with melted ice and water. They often have unique characteristics, such as a circular shape and steep sides.

The Glacial Lakes that helped to form the 'Plains' topography of North Dakota do not exist today. Several Glacial Lakes have been identified and named by geologists, however. Some of them were:Lake Souris,Lake Dakota,Lake McKenzie,and the largest, Lake Agassiz, which was named after Louis Agassiz (1807-1873), who is honored as the father of glacial geology.

Glacial erosion occurs when glaciers move through an area, gouging into the land beneath. In areas where the soil is relatively soft, glaciers can gouge out areas that eventually turn into lakes.
