LAKE ERIE FACTS
GEOLOGICAL
The lake was gouged out by glacial ice between 1 million and 12,600 years ago.
It was one of the first Great Lakes to be uncovered during the last retreat of the glacial ice.
The oldest rocks from which the Lake Erie basin was carved are about 400 million years old and formed in a tropical ocean-reef environment.
Lake Erie and its shoreline are a major source of many minerals. The largest sandstone quarry in the world is located in Amherst, Lorain County, Ohio. Salt mines in Cuyahoga and Lake Counties extend out under Lake Erie and are an important source of revenue to the State. Sand, gypsum, and limestone used for construction purposes are found in abundance. Large reserves of natural gas, over 3 trillion cubic feet, are located under Lake Erie.
PHYSICAL
Lake Erie is the 12th-largest (area) lake in the world, and its border includes four states (NY, PA, OH, MI) and one Canadian Province (Ontario).
Lake Erie is the southernmost, shallowest, warmest, and most biologically productive of the five Great Lakes.
Lake Erie has three basins: the western basin includes the islands area, the central basin extends from the islands to Erie, PA, and Long Point, Canada, and the eastern basin extends from Erie, PA, to the east end of the lake.
Lake Erie is about 210 miles (338 km) long, about 57 miles (92 km) wide, and has a shoreline length of about 871 miles (1,400 km).
The maximum depth is 210 feet (64 m). Average depths in the basins are: western, 24 feet (7.3 m); central, 60 feet (18.3 m); and eastern, 80 feet (24.4 m).
The water surface area is 9,906 square miles (25,657 sq. km) and the volume is 116 cubic miles (483 cu. km).
Lake Erie's drainage basin area is 22,720 square miles (58,800 sq. km) and has a retention/replacement time of 2.6 years, which is the shortest of the Great Lakes.
Water flow from the Detroit River makes up 80 to 90% of the flow into the lake.
The outlet for Lake Erie is the Niagara River; consequently, it is Lake Erie that feeds water to Niagara Falls.
Basin rainfall is about 34 inches per year, although the historical trend is increasing slightly.
About 34 inches of water evaporates from the lake surface per year.
Elevation of the Low Water Datum (chart "0") is 568.6 feet above Father Point, Quebec. Average water elevation is about 570 feet above the same point.

The shallowest lake in the world is the one in my backyard! It's only about 6-8" deep at it's deepest point.

Wikipedia says Lake Erie.
It's by Michigan, Ohio, New York, Pennsylvania (USA) and Ontario (Canada).
