Lake Warren was a proglacial lake that formed in the Lake Erie basin around 12,700 years before present (YBP) when Lake Whittlesey dropped in elevation. Lake Warren is divided into three stages: Warren I 690 feet (210 m), Warren II 680 feet (210 m), and Warren III 675 feet (206 m), each defined by the relative elevation above sea level.
Using National Elevation Datasets (NEDs) from the USGS, the author incorporated the 275-meter (902-foot) contour elevations into a GIS, spatially correlated the contours with Ohio Department of Natural Resources' GIS glacial, geologic, and topographic datasets, and developed a revised lake boundary that shows the areal extent of Proglacial Lake ...

A map of the Great Lakes Basin showing the five sub-basins. Left to right they are: Superior (magenta); Michigan (cyan); Huron (green); Erie (yellow); Ontario (red). Though the five lakes lie in separate basins, they form a single, naturally interconnected body of fresh water, within the Great Lakes Basin. As a chain of lakes and rivers, they ...
It is the shallowest of the Great Lakes with an average depth of 10 fathoms 3 feet or 63 ft (19 m) [7] and a maximum depth of 35 fathoms (210 ft; 64 m) [7] [8] Because Erie is the shallowest, it is also the warmest of the Great Lakes, [17] and in 1999 this almost became a problem for two nuclear power plants which require cool lake water to ...
Nipissing Great Lakes was a prehistoric proglacial lake. Parts of the former lake are now Lake Superior, Lake Huron, Georgian Bay and Lake Michigan. It formed about 7,500 years before present (YBP). The lake occupied the depression left by the Labradorian Glacier. [1] This body of water drained eastward from Georgian Bay to the Ottawa valley.
Ohio has 110 lakes larger than five acres of land, with a total surface area of over 4,500 acres. Twenty-one of Ohio's 88 counties have natural lakes. Here are ten of the biggest natural lakes in ...
The following is a list of lakes in Ohio. According to the Ohio Department of Natural Resources , there are approximately 50,000 lakes and small ponds, with a total surface area of 200,000 acres, and among these there are 2,200 lakes of 5 acres (2.0 ha) or greater with a total surface area of 134,000 acres.
