Michigan occupies 38,575 square miles of the Great Lakes water area, with 58,110 square miles of land and 1,305 square miles of inland water. Lake Superior is the largest and deepest of these lakes.
It has a surface area of 31,700 square miles and is approximately 400 miles long. Its depth reaches over 1,300 feet at its deepest point – making it the second deepest North American freshwater lake after only Great Slave Lake in Canada.
Lake Superior’s average depth is 483 feet, with a mean elevation that stands at 600 feet above sea level. There are two islands within this vast body of water which are larger than any other located on the Great Lakes: Isle Royale and Grand Island in Michigan.
The shoreline surrounding this impressive lake spans four US states Minnesota, Wisconsin, Michigan’s Upper Peninsula (US), and Ontario (Canada). As it flows eastwards through its connection to the St. Mary’s River in the Sault Ste Marie Michigan-Ontario boundary, it drains into Lake Huron, forming part of The Great Lakes Waterway system used for transportation today.
Overall, Lake Superior hosts more than one hundred streams and rivers that form quite a unique environment around its coastline, as well as hold many ancient shipwrecks down on its bottom – offering plenty of opportunities for recreational activities such as fishing, diving, or pleasure boating.

What is the Deepest Lake in Michigan?

Michigan’s Lake Superior is the deepest in the entire state. Its depth reaches around 480 feet and spans four states.
However, as it also involves other state boundaries, it can’t be said to have Michigan’s deepest inland lake. That accolade belongs to Torch Lake, which spans 19 miles long and with a maximum depth of nearly 300 feet.
It is known for its crystal clear water and deep blue color, which makes it an attractive spot for swimming and fishing. Its bottom consists mainly of sand and gravel, making it an ideal spot for divers as well.
With its national popularity rising year after year, Torch Lake serves as one of Michigan’s great natural attractions.
Deepest Lake in Michigan: Lake Superior
Lake Superior is one of the most popular lakes in North America. It’s the largest, coldest, northernmost, and deepest of the five Great Lakes. It holds 10% of all freshwater on the planet’s surface, making it the world’s largest freshwater lake by surface area.
The ecology of Lake Superior is unmatched among freshwaters. Aquatic life thrives here, from sea lamprey to sturgeon and more. Additionally, its underwater visibility surpasses many other places and puts it in a class of its own.
Lake Superior’s magnificence has stood for centuries and will continue to bring visitors from all over the world to experience its grandeur for decades to come. Its size gives a sense of awe; its beauty adds yet another layer to an already impressive oasis in nature.
How Deep is Lake Superior?
Lake Superior is deep and huge: 1,333ft with a 350-mile length, 160-mile width, and over 2,900 cubic miles of water. It holds total water than the other Great Lakes combined. Limited freezing occurs here due to its vast depths and crystal clear waters with visibility up to 30 meters!
It’s not all good news, though, as its so-called ‘Great Power’ also attracts ships, many of which remain wrecks in its depths. It is the third-lowest point in North America (following Great Slave Lake). 1985 saw J Val Klump become the first person to reach the lake’s bottom. We must care for this powerful entity!
Shipwrecks in Lake Superior

Lake Superior is known for its treacherous waters. This lake has recorded over 350 shipwrecks and caused the loss of nearly 10,000 lives. The frigid waters have been the cause of countless lost lives, and many bodies remain unaccounted for.
One of the most catastrophic disasters to occur on Lake Superior was the sinking of the SS Edmund Fitzgerald in 1975. This vessel was the biggest to cross the Great Lakes, and a crew of 29, unfortunately, perished with it.
Even though several rescue attempts were launched, all efforts were fruitless, and this event became the worst wreck ever on these famous waters.
This incident serves as a reminder that Lake Superior is not to be taken lightly due to its unpredictable depth and weather conditions. Whenever out at sea, extra precautions must be taken to ensure the safety of everyone involved.
Deepest Inland Lake in Michigan: Torch Lake
Torch Lake, in Michigan, is famed for its turquoise-blue water and activities. Its resemblance to the Caribbean Sea earned it its nickname: the ‘Caribbean Lake.’ It’s the state’s deepest inland lake and a beloved vacation spot for locals and tourists alike.
Activities around Torch Lake include swimming, boating, fishing, paddling, and kayaking. A favorite for many is renting a pontoon boat to explore the coastline. With 18 miles of shoreline that stretches from East Jordan to Bellaire, you can go for long treks with beautiful scenery along the way.
The lake is also home to wildlife: bald eagles swooping above looking for fish, blue herons lifting off from their perches, and geese honking from their homes in various coves. Torching stays cool year-round due to its depths reaching nearly 250 feet deep in some areas (it’s even been known to be charted down by submarines!).
For those looking to do more than just splash around in the water, Torch Lake offers plenty of campgrounds nearby, as well as nearby attractions like antique stores, wineries, and golf courses. Visitors can take advantage of local festivals like Dragon Fish Races or catch a show at Candle Water Park on summer evenings!
How Deep is Torch Lake?
Torch Lake is the deepest inland lake in Michigan, maxing out at 310ft. The 19-mile-long lake spans 18,770 acres and has an average depth of 111ft – though the exact figure is disputed. It has a summertime temperature of 71°F.
The lake is almost as big as Houghton Lake, which makes it Michigan’s second-largest inland lake. Its maximum depth gives it unique characteristics, making it different from smaller lakes like nearby Skegemog Lake.
There’s debate about Torch Lake’s actual deepest point, with figures ranging from 285ft to 350ft. Despite this, one thing’s for sure: at 310ft, Torch Lake really lives up to its name.
Why Does Torch Lake Have Caribbean-Like Waters?
Torch Lake has a special feature that makes it similar to the Caribbean Sea: its bottom is mostly limestone granules. There’s no darkness or color to the lake water because of its fine calcium carbonate sediment and little organic matter. This explains why it looks like the Caribbean. Torch Lake used to be part of Lake Michigan, but an outlet sandbar split them apart.
Limestone is a sedimentary rock made mainly from calcite or dolomite. It occurs in various forms in nature as chalk, marble, travertine, and coral fossils. The glacial activity was responsible for forming limestone grains in Torch Lake during the last ice age. The lake gets its brilliant blue color from this fine silt that sits on its bed and reflects sunlight and sky colors back up into the water body.
An important part of maintaining Torch Lake’s unique beauty is avoiding activities that can cause pollutants or materials to enter the lake (such as runoff from community gardens).
Floating booms across northern arms help to reduce phosphorus levels which then prevents algae production in the lake, while oxygenation systems also play an important role in keeping waters clean and healthy.
Overall, this provides clearer water visibility and better habitat for wildlife that benefits from these clearer conditions, including game fish species popular with anglers.
