How Much Fresh Water is in the Great Lakes


There are five Great Lakes in North America and they hold about 20% of the world’s fresh surface water. The Great Lakes contain 6 quadrillion gallons of water which is enough to cover the entire continental United States with almost 10 inches (25 cm) of water. The average depth of the lakes is about 179 feet (55 m) and the deepest lake, Superior, has a depth of 1,335 feet (407 m).

The Great Lakes hold about 84% of the world’s fresh surface water and about 22% of the world’s total freshwater. That means that these five lakes — Superior, Huron, Michigan, Erie, and Ontario — hold more than one-fifth of all the unfrozen water on Earth! And yet, as large as they are, the Great Lakes only make up a small fraction of North America’s surface area.

Think about it this way: If all the continents were flattened out into a single landmass, the Great Lakes would cover less than 3% of it. In other words, if you took all seven billion people on Earth and lined them up shoulder to shoulder, each person would have an allotted space that is approximately 30 times larger than one of the Great Lakes. But don’t let their size fool you; even though they’re comparatively tiny when compared to dry land, the Great Lakes contain a staggering amount of water.

In fact, if all that water were evenly distributed across North America’s landmass (again, including Greenland), every piece of ground would be covered in nearly two feet (60 cm) of water!

Which Great Lake is the Deepest

The Great Lakes are a group of five large freshwater lakes in North America. They include Lake Superior, Lake Huron, Lake Michigan, Lake Erie, and Lake Ontario. The Great Lakes region is home to one-fifth of the world’s fresh surface water.

Superior is the deepest (1,335 ft/406 m) and largest (31,700 mi²/82,103 km²) of the Great Lakes by area. It’s also the coldest and most pristine lake in the world. In fact, Superior is so big and deep that it could hold all of the other Great Lakes plus three more lakes the size ofLake Erie!

That would make one huge lake! Huron is next in line as the second largest Great Lake ( 23,010 mi²/59,596 km²) with a depth of 750 ft / 229 m . Like Superior , Huron is very cold and has very clean water .

In fact , these two lakes are sometimes referred to as “the sister lakes.” Michigan is third largest at 22,400 mi² (58,016 km²) with a depth of 925 ft / 282 m . It’s also the only lake entirely within the boundaries of the United States .

Michigan is bordered by Wisconsin on its west shoreline and Illinois & Indiana to its south. Fun fact: about 38% of Michigan’s coastline lies within state parks ! Whew!

Now that we know which Great Lake is deepest , let’s take a look at some fun facts about each one: -Did you know that all five Great Lakes together contain 20% of Earth’sfreshwater? -Or that they hold enough water to cover North & South America up to an average depthof 9 feet (2.7 meters)?

-How about that their combined shorelines stretch for 8200 miles(13184 kilometers)? Incredible , right? Nowhere else in the world will you find a concentrationof freshwater like this !

How Much Fresh Water is in the Great Lakes


Are the Great Lakes the Largest Freshwater System?

The Great Lakes are the largest freshwater system in the world. Comprising of five lakes – Superior, Huron, Michigan, Erie and Ontario – this system covers an area of over 94,000 square miles. And while each lake is impressive in its own right, together they form an ecosystem that is truly unrivaled.

But just how did these massive lakes come to be? It all started with the last ice age. As the glaciers began to retreat, they left behind huge depressions in the earth’s surface.

These depressions eventually filled with water and formed what we now know as the Great Lakes. Over time, the Great Lakes have become an important part of both the local and global economy. They provide a source of fresh water for millions of people and are home to a vast array of plant and animal life.

The lakes also support a thriving tourism industry, drawing in visitors from all over the world who come to enjoy their beauty and recreational opportunities. There’s no doubt that the Great Lakes are an amazing natural wonder – but they’re also vitally important to our way of life. We must do everything we can to protect them for future generations to enjoy.

Are the Great Lakes All Freshwater?

Yes, the Great Lakes are all freshwater. They are actually the largest group of freshwater lakes in the world! The Great Lakes contain 21% of the world’s surface fresh water by area, and they hold about 84% of North America’s fresh water by volume.

Why Can’T We Pipe Water from the Great Lakes to California?

There are a few reasons why we can’t pipe water from the Great Lakes to California. First, the Great Lakes are actually a system of freshwater lakes located in North America, specifically in the upper Midwest region of the United States. This means that they’re not connected to any ocean, so there’s no easy way to transport the water over long distances.

Second, even if we could transport the water, it would be very expensive to do so. The Great Lakes contain about 20% of the world’s fresh surface water, so it would take a lot of energy and money to pump all that water out and send it west. Finally, there are environmental concerns about taking such a large amount of water out of the Great Lakes basin.

This could potentially disrupt local ecosystems and affect the people who depend on them for their livelihoods.

Are the Great Lakes Saltwater? Or Freshwater?


The Great Lakes hold 20% of the world’s fresh surface water, making them an important natural resource. However, the amount of fresh water in the lakes is not static – it fluctuates depending on precipitation, evaporation, and other factors. Currently, Lake Superior holds the most fresh water at around 3 quadrillion gallons (or about 12% of the total fresh water in the Great Lakes).

This is followed by Lake Huron with 2.8 quadrillion gallons (11%), Lake Michigan with 1.3 quadrillion gallons (5%), Lake Erie with 0.6 quadrillion gallons (2%), and finally Lake Ontario with 0.4 quadrillion gallons (1%).
