Lake Superior is the world's largest freshwater lake by area (31,700 mi2 /82,100 km2). It is also the coldest and deepest of the Great Lakes, with a maximum depth of 406 meters (1,332 feet). By most measures, it is the healthiest of all the Great Lakes.
At the deepest measured point, Lake Superior is 1,332 feet, around a quarter-mile straight down. Again, comparing it to the next deepest point in another Great Lake, Lake Michigan comes in second with a depth of 925 feet.
The largest lake in the world is the Caspian Sea. Although it is often considered a sea because of its size and salinity, it is technically classified as an endorheic lake. With a surface area of around 371,000 km², the Caspian Sea far exceeds any other lake in terms of size.
Why is Lake Erie so important? Erie is the most biologically productive and diverse of all the Great Lakes due to its warm shallow waters. Alongside this astounding biodiversity, more than 11 million people get their drinking water from the Lake Erie watershed.
Lake Superior is the Cleanest and Clearest Great LakeBecause of its somewhat isolated location and long cold winters, not much farming is done along Superior's shores. This means lower amounts of nutrients, sediments, and organic material are floating around the lake.
Lake Michigan wrecks: the oldest and the mostestLake Michigan contains more shipwrecks than any of the other Great Lakes, as well as the oldest recorded one: the French ship Griffon, the first European vessel to sail the Lakes.

The State of the Great Lakes 2022 Report by the Michigan Department of Environment, Great Lakes and Energy have analyzed and reported that Lake Superior and Lake Huron are rated as “good” ecosystems as Lake Michigan and Lake Ontario are rated “fair” and Lake Erie was ranked as “poor.”
Currents in Lake Erie can be dangerous! Any current flowing faster than 2 mph is considered dangerous. Dangerous currents can exceed 5 mph — faster than an Olympic swimmer can swim. Currents can pull swimmers away from shore.
Lake Erie has a lake retention time of 2.6 years, the shortest of all the Great Lakes. The lake's surface area is 9,910 square miles (25,667 km2). Lake Erie's water level fluctuates with the seasons as in the other Great Lakes.
The Great Lakes aren't all that great, in terms of depth anyway. At over a mile deep (1,642 meters or 5,387 feet) Lake Baikal in the Russian region of Siberia is the deepest lake in the world.
According to the USDA, the average depth of Lake Tahoe is 1,000 feet. The elevation at the deepest part of the lake is 4,585 feet above sea level. You could drive west on I-80 all the way to Emigrant Gap (over 40 miles from Tahoe City) and still be 500 feet higher than the deepest part of Lake Tahoe.
Lake Erie is the fourth-largest lake in North America (by surface area) and the eleventh-largest worldwide. It is the Great Lakes' southernmost, shallowest, and smallest by volume. By the 1960s, Lake Erie had become the most polluted of the Great Lakes, owing to the substantial industrial presence along its coasts.
Lake MichiganThe Great Lakes are all water bodies that swimmers should think twice about entering. Lake Michigan in particular is the roughest of the Great Lakes, and poses a major risk to those thinking of taking a dip. This body of water is often named the most dangerous lake in the United States.
Lake Erie is the warmest, most shallow and most biologically diverse of the North American Great Lakes, home to 107 species of fish (90 native, 17 introduced) making it one of the largest freshwater fisheries in the world.
During the 1960s, Lake Erie was declared a “dead lake” due to eutrophication and pollution. The children's book, The Lorax, written by Dr. Seuss, actually included the following line referring to fish: “They will walk on their fins and get woefully weary in search of some water that isn't so smeary.
In the deeper waters of Lake Erie's central basin, the process of decomposition depletes the oxygen in the bottom waters. When this oxygen-deficient water interacts with Erie's lakebed sediments and clay, heavy metals such as manganese and iron are released from the muck into the water.
Lake Erie is the second smallest Great Lake by surface area, and the smallest by volume. Because of this, the water of Lake Erie also has the shortest residence time. Water in this lake replaces itself every 2.6 years, as opposed to Lake Superior, which takes two centuries.
