Visualized: The Depth of The Great Lakes
Click here to view the interactive version of the visualization on Tableau.
As the seasons change, it’s natural to want to enjoy the outdoors to the fullest. The Great Lakes, a distinct geographical region sandwiched between the U.S. and Canada, provides immense opportunity for millions of tourists to do just that every year.
But did you know that altogether the Great Lakes contain 21% of the world’s surface freshwater by volume—or 84% of the surface freshwater in North America?
This bathymetric visualization, created by Alex Varlamov, helps put the sheer size and depth of all five of the Great Lakes into perspective.
What is Bathymetry?
Bathymetry is the study of the underwater depth of ocean or lake floors, a geographical science that falls under the wider umbrella of hydrography.
In essence, it is the underwater equivalent of topography. Contour lines help to represent and study the physical features of bodies of water, from oceans to lakes.
Most bathymetric studies are conducted via sonar systems, transmitting pulses that ‘ping’ off the ocean and lake floor, uncovering what lies below.
The Depth of the Great Lakes, Compared
High on the list of the world’s largest lakes, the five Great Lakes altogether account for over 244,700 km² (94,250 mi²) in total surface area. That’s bigger than the entire United Kingdom.
Lake Superior emerges, well, superior in terms of total surface area, water volume, and both average and maximum depth.
|Surface area||Water volume||Average depth||Maximum depth|
|Lake Ontario||19,000 km²|
|Lake Erie||25,700 km²|
|Lake Michigan||58,000 km²|
|Lake Huron||60,000 km²|
|Lake Superior||82,000 km²|
Lake Erie is by far the shallowest of the lakes, with an average depth of just 19 meters (62 ft). That means on average, Lake Superior is about eight times deeper.
With that in mind, one drawback of the visualization is that it doesn’t provide an accurate view of how deep these lakes are in relation to one another.
For that, check out this additional visualization also created by Alex Varlamov, which is scaled to the same 20 meter step—in this view, Lake Erie practically disappears.
More than Meets the Eye
The Great Lakes are not only notable for their form, but also their function—they’re a crucial waterway contributing to the economy of the area, supporting over 50 million jobs and contributing $6 trillion to gross domestic product (GDP).
Together, the five Great Lakes feed into the Atlantic Ocean—and when we expand the scope to compare these lakes to vast oceans, trenches, and drill holes, the depth of the Great Lakes barely scratches the surface.
Mapped: How Much Does it Take to be the Top 1% in Each U.S. State?
An annual income anywhere between $360,000-$950,000 can grant entry into the top 1%—depending on where you live in America.
How Much Does it Take to be the Top 1% in Each U.S. State?
There’s an old saying: everyone thinks that they’re middle-class.
But how many people think, or know, that they really belong to the top 1% in the country?
Data from personal finance advisory services company, SmartAsset, reveals the annual income threshold at which a household can be considered part of the top 1% in their state.
Some states demand a much higher yearly earnings from their residents to be a part of the rarefied league, but which ones are they, and how much does one need to earn to make it to the very top echelon of income?
Ranking U.S. States By Income to Be in the Top 1%
At the top of the list, a household in Connecticut needs to earn nearly $953,000 annually to be part of the one-percenters. This is the highest minimum threshold across the country.
In the same region, Massachusetts requires a minimum annual earnings of $903,401 from its top 1% residents.
Here’s the list of all 50 U.S. states along with the annual income needed to be in the 1%.
|Rank||State||Top 1% Income|
|Top 1% Tax Rate
(% of annual income)
California ($844,266), New Jersey ($817,346), and Washington ($804,853) round out the top five states with the highest minimum thresholds to make it to their exclusive rich club.
On the other end of the spectrum, the top one-percenters in West Virginia make a minimum of $367,582 a year, the lowest of all the states, and about one-third of the threshold in Connecticut. And just down southwest of the Mountain State, Mississippi’s one-percenters need to make at least $381,919 a year to qualify for the 1%.
A quick glance at the map above also reveals some regional insights.
The Northeast and West Coast, with their large urban and economic hubs, have higher income entry requirements for the top 1% than states in the American South.
This also correlates to the median income by state, a measure showing Massachusetts households make nearly $90,000 a year, compared to Mississippians who take home $49,000 annually.
How Much Do the Top 1% Pay in Taxes?
Meanwhile, if one does make it to the top 1% in states like Connecticut and Massachusetts, expect to pay more in taxes than other states, according to SmartAsset’s analysis.
The one-percenters in the top five states pay, on average, between 26–28% of their income in tax, compared to those in the bottom five who pay between 21–23%.
And this pattern exists through the dataset, with higher top 1% income thresholds correlating with higher average tax rates for the wealthy.

These higher tax rates point to attempts to reign in the increasing wealth disparity in the nation where the top 1% hold more than one-third of the country’s wealth, up from 27% in 1989.
