The Great Lakes are the largest glacial lakes in the world. The prehistoric glacial Lake Agassiz once held more water than contained by all lakes in the world today. A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier.
Lake Agassiz (/ ˈ æ ɡ ə s i / AG-ə-see) was a large proglacial lake that existed in central North America during the late Pleistocene, fed by meltwater from the retreating Laurentide Ice Sheet at the end of the last glacial period.
The lake measured about 7,770 square kilometres (3,000 sq mi) and contained about 2,100 cubic kilometres (500 cu mi) of water, half the volume of Lake Michigan. [1] The Glacial Lake Missoula National Natural Landmark is located about 110 kilometers (68 mi) northwest of Missoula, Montana, at the north end of the Camas Prairie Valley, just east ...
Lake Ojibway was a prehistoric lake in what is now northern Ontario and Quebec in Canada.Ojibway was the last of the great proglacial lakes of the last ice age. [2] Comparable in size to Lake Agassiz (to which it was likely linked), and north of the Great Lakes, it was at its greatest extent c. 8,500 years BP.
After the lake drained, the ice would reform, creating Glacial Lake Missoula again. These floods have been researched since the 1920s. During the last deglaciation that followed the end of the Last Glacial Maximum , geologists estimate that a cycle of flooding and reformation of the lake lasted an average of 55 years and that the floods ...

Glacial Lake Columbia was the lake formed on the ice-dammed Columbia River behind the Okanogan lobe of the Cordilleran Ice Sheet when the lobe covered 500 square miles (1,300 km 2) of the Waterville Plateau west of Grand Coulee in central Washington state during the Wisconsin glaciation. [1]
Glacial Lake Iroquois was a prehistoric proglacial lake that existed at the end of the last ice age approximately 13,000 years ago. [2] Description
