What is the difference between a man-made lake and a glacial lake?
I have no idea, when you find out edit here.
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.
