About Lake Superior
Lake Superior is the largest and deepest of the Great Lakes, with a surface area of 31,700 square miles, and a maximum depth of 1,276 ft. Very young by geological standards, it is only 10,000-years old. The lake that is so large it takes about 200 years to replenish its water supply and it holds 10% of the world’s surface freshwater. It is the northernmost of the five Great Lakes bordered by Ontario, Canada, Michigan, Wisconsin, and Minnesota.

With the surface temperature averaging around 63 degrees Fahrenheit and having just over 1,800 miles of shoreline, it may seem like an inviting lake, especially for a swim. However, being almost a quarter-mile deep and exposed to harsh winters, the water gets cold quickly.
How Cold Is the Bottom of Lake Superior?
The water temperature at the bottom of Lake Superior averages 39 degrees Fahrenheit, which is too cold for most plants and animals to survive. However, a few species can withstand the chilly conditions. These include various types of bacteria, sponges, worms, and crayfish. Let’s learn more about what lives on the lake bottom.
What Lives on the Bottom of This Chilly Lake?
Because of the cold temperatures, Lake Superior is a relatively infertile lake that is not very biodiverse compared to most other lakes. While most animal species can’t handle the cold temperatures at the bottom of Lake Superior, some thrive there. However, you wouldn’t see much at the bottom. The lake is so deep that sunlight barely penetrates, and most bottom-dwellers are dark-colored to blend in with their surroundings. But that doesn’t mean there’s nothing down there.
More than 200 species of fish live in the lake, including walleye, whitefish, and sturgeon. It also has several bottom-dwelling fish species, such as the invasive round goby. Additionally, the bottom of the lake is home to crayfish, shrimp, and other invertebrates.
Plants such as algae and seaweed also grow in the depths. The lake bottom is a diverse and productive ecosystem that supports a wide range of plant and animal life. But it holds much more than that. It contains hundreds of shipwrecks…and bodies.
How Many Bodies Are at the Bottom of Lake Superior?
This question has long intrigued researchers and casual observers. The answer, unfortunately, is not clear. We have no reliable estimates of how many people have drowned in the lake over the years, and the bodies found are only a fraction of the total.
The bottom of Lake Superior is a vast and remote place, and it is very difficult to search for people. Additionally, the lake is extremely cold and hostile to human life, making it very unlikely that any remains would be well preserved.
As a result, the number of bodies at the bottom of Lake Superior will probably never be known. But if you do need a number, some say the lake has taken over 20,000 people.

Does Lake Superior Give Up Her Dead?
As legend has it, Lake Superior never gives up her dead. For centuries, people have wondered about the strange lights and noises that come from the lake’s depths.
Some say that the lights are ghosts and that the noises are the sounds of their restless spirits. Others believe that the bottom of the lake is home to a different kind of creature altogether. Whatever the case, the lake is full of mystery and intrigue.
However, scientists have other reasons for Lake Superior never giving up her dead. Because of the cold water, bacteria don’t grow like they would in warmer waters. Bacteria causes a body to bloat and eventually float to the surface.
The cold temperatures here help keep the bodies down in the depths. She does not give up her dead, but maybe she will eventually reveal the many other secrets that lie in the depths.

How Many Ships Are at the Bottom of Lake Superior?
The bottom of Lake Superior has an estimated 550 shipwrecks. Estimates of around 10,000 people have been lost to the lake. One of the worst wrecks came from the Ophelia, a steamer that sank in 1854. The Ophelia carried 150 passengers and crew when she went down in a storm. Only two people survived.
The Edmund Fitzgerald, another well-known shipwreck, sank in 1975 with all 29 crew members aboard. People believe that the ship took on water due to leaking hatches and the huge waves eventually broke the ship in half.
The bottom of Lake Superior is also home to hundreds of other shipwrecks. These wrecks remind us of the dangers of navigation on the Great Lakes.
What About the Legend of the Underground Lake?
Lake Superior has many secrets, including an underground lake. Sounds a bit mythical, right? Legend has it that the floor of Lake Superior has an opening into a subterranean cave. A French explorer who came across it in the 1600s initially called it the Lake of Hell. But the true meaning got lost in translation when English speakers misunderstood it to be Lake Inferior.
Fast forward a few hundred years when in 1870, some city workers fixing a wall discovered it and wanted to plug the entrance to the cave. They thought it would have an impact on shipping and transportation.
While a myth, it has some truth to it. Rather than an underground lake, scientists would refer to this as groundwater. This hidden body of water under the Great Lake Basin contains as much water as all of Lake Huron. The groundwater provides a vital habitat for rivers and surrounding ecosystems that it drains into. It also helps to regulate the temperature of the water in Lake Superior. Unfortunately this groundwater is becoming more and more polluted and is a source of much pollution entering the great lakes.
Is Lake Superior Worth Visiting?
With Lake Superior containing as much water as all the Great Lakes combined and then some, this majestic expanse of water is most definitely worth a visit. Then when adding in the mystique of, shipwrecks, bodies, and unique plants and wildlife, Lake Superior becomes a must-do experience. Although we may be a little biased as the shores of lake superior have been our summer home for many years.
In fact, you can explore the vast lake and region again and again. After all, the bottom of Lake Superior is a mystery worth diving into.
