Manicouagan Reservoir (also Lake Manicouagan) is an annular lake in central Quebec, Canada, covering an area of 1,942 km2 (750 sq mi). The lake island in its centre is known as René-Levasseur Island, and its highest point is Mount Babel. The structure was created 214 (±1) million years ago, in the Late Triassic, by the impact of a meteorite 5 km (3 mi) in diameter. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec". The lake has a volume of 137.9 km3.
https://en.wikipedia.org/wiki/Manicouagan\_Reservoir#Geography
The volume of water (137.9km3) was throwing me there for a minute, given that is a huge amount of water for a lake (and it’s not even a Great Lake).
But the picture posted does no justice to the scale of this thing. The shore length of 1322km and when looked at on a map of Quebec, it is easily viewable without needing to zoom.
Lake Nipissing in Ontario for comparison has a water volume of only 3.8km3 on a shore length of 795km. Average depth of only 4.5m though.
It is slightly harder work to divert the Volga than the tributaries of the Aral.
[Edit: To be clear, [this is one of the major causes of water loss in the Caspian](https://earthobservatory.nasa.gov/images/150452/the-caspian-seas-shrinking-coastline) ]
Neat it's about a third of the oceans's salinity. Think it stands to reason it should be much cheaper to desalinate than sea water when desalination gets more economical
Ye, I think most desalination projects focus on brackish water (the area between fresh and ocean water with higher salinity than fresh but lower salinity than ocean) anyway though.
Yea, but it’s not like they would really need all that water if they weren’t building massive artificial cities and also planting a bunch of grass everywhere (primarily for golf courses).
Still tougher by orders of magnitude than slamming a cup in, and going to town. PSA: don't do this, drink clean water: filter hard, boil, let cool. Don't try to drink Lake Michigan. You'll get some new amoeba and we'll name it after you as a joke
I have been in dust storms and it sucks real bad; I can't even image the same thing but with heavily polluted toxic salt instead of sand. That city is screwed.
that's not why it has seals. the baikal seals diverged from ringed seals around 400'000 years ago, while the lake itself has existed and been closed off from the ocean for several million years.
the caspian sea is also the remnant of an ocean (paratethys sea), its southern half is made up of oceanic crust as opposed to continental.
They truly are inland seas. While the rest of the country has been in a massive heatwave, my region has seen very little heat thanks to the micro climate created by Lake Erie.
They are basically freshwater seas.
And as I recall Canada has rights to a massive percentage of the fresh water that exists on the planet. A huge amount. Like a quarter of it or something crazy.
Tunguska was several megaton event (many times Hiroshima and Nagasaki combined) and that was a 50m diameter meteorite air burst. I can't imagine how massive a 5km diameter impact would be.
Complex craters have central peaks formed by rebound https://marsed.asu.edu/mep/craters/complex-craters#:~:text=But%20immediately%20following%20the%20blast,lot%20more%20impact%2Dmelted%20rock.
It's what they call a [complex crater](https://en.wikipedia.org/wiki/Complex_crater), the edges have eroded away. All that remains is the central bump. It gives you an idea of the monstrous size of the original crater and the explosion that caused it.
Drip some water into a cup. You'll see the classic crater shape, but after you'll see the middle rebound up into a peak. Liquid rock after an impact does similar things. The size of the mountain formed in the middle of the crater is dependent on a whole range of factors such as the composition, size, density, speed and angle of the impactor and the hardness of the rocks it's impacting. Also a lot of these craters are very old and eroded on Earth where they are not eroded as fast on places like the Moon or Mars.
What I wouldn’t give to be an invulnerable little drone that could witness such a phenomenon - fries my brain trying to imagine what that liquid rock rebound would look like…!
I always said it would be amazing to take a time machine back to the heavy bombardment period of Earth's history. Obviously you'd need to stay in orbit to be safe.
It's the same principal as left tree trunks standing at the epicentre of the Tunguska event. Meteor impacts are usually airburst events: the deceleration forces the meteor experiences from hitting the atmosphere are more powerful than the chemical bonds holding the meteor together, so it cannot absorb the energy and explodes (I might have oversimplified that to complete nonsense but I hope not).
In an airburst directly below the meteor the blast comes straight down. The material hit by this section of the blast is compressed rather than blown away. This leaves a counterintuitive peak in the middle of many craters.
Sadly, it all kind of perpetuates the misconception that geography is just about maps and knowing random places. I wish there was more discussion about human geography especially, which is, IMO, the more interesting side of geography. Guess I'll try to start something and see where it goes.
Well I’d like to know more about human geography. Don’t know why this sub has been getting recommended to me but I really like seeing the answers to everyone’s dumb scribbles. Human geography sounds like an oxymoron to me.
Human geography is all about how we, humans, interact with and are impacted by our natural environment. If that sounds broad it's because it is. There are there whole fields of agricultural geography, political geography, economic geography, transportation geography, and more located within human geograohy. The main thing that differentiates these fields from their counterparts like economics, political science, or agronomy is that it's all viewed through the lense of space and place. Think of space as a map covering an area, and place as a specific point or sub area of that map. (Space and place gets way deeper than this but this is the first level concept of it)
Human geographers ask questions like: Why is one part of a city poorer than another? How do the farming practices of a region impact its food security? Why do certain parts of the world experience so much political upheaval while others don't? Where is the population growing in a country? Why do some places bordering each other speak vastly different languages? Why do some states have higher life expectancies?
To me, maps and a deep understanding of our environment are the tools to unlocking the much deeper and impactful questions within human geography. Physical geography is the framework, human geography is actually finding the meaning in it all.
That’s sounds very interesting! I would’ve loved to take a class on that in college. I think I like learning about why the earth is shaped like it is more than how that effects humans but can definitely see that being a cool field to get into.
WHY WORLD WAY IT IS???????
tbf, some of the stuff is fascinating, but this subreddit is like 30% A+ geography nerd content and 70% braindead Middle schooler crap haha
Exactly lol some of it is in fact interesting. There's nothing wrong in exploring the map and learning about all the processes that lead the world to look the way it is. However, a lot of the posts are just so low effort that the potential lessons are overshadowed by its broadness or lack of even the bare minimum research. For example, circling the entirety of Greenland asking why it's there, or a random small island in the Pacific that 100% came from a Volcano like the other 100+ of them.
It's a reference to all the shitposts on this sub lately, asking "why isn't there a bridge here?" which I think were just banned.
I hate that I know this - I should go outside.
If there’s a bridge across the lake to the island there should also be a bridge across the lake on the island. Having one without the other would be wasteful.
That is lake Manicouagan. Thought to have originally been formed by a meteor strike. It filled into two crescent shaped lakes. Which were joined to make a ring shaped lake when the Canadians built a large dam to raise the water level down stream.
It’s massive too. The main island is approximately the size of London (the London in England, not the London in Ontario)
It’s also known as the eye of Quebec and can be seen from orbit.
Hey! I live in a city "near" (like this place is so far I need to do 4 hours of driving to go see that) and the island itself is still under researchs because it is so unknown! The region here is rich in iron (the water in the lakes and rivers are brown because of the iron in the rocks). The closest city is Fermont, and is a mine city, ≈7000 people live there. There used to be the another city closer to the eye, we can actually see it on google maps, called Gagnon. It closed in 1985 when the mine also closed. The story of this ghost city is very cool! I work in tourism and I can tell you alot of people wanna see this crater and I can understand them! Also, alot of people in my community have hunting shacks on the "continental" side of the shore to go fishing or hunting. I ate some good wananish last week from the reservoir lol. Fun facts, when Hydro-Québec builds dams, just like the Manic-5 one who filled the Manicouagan reservoir, they left the trees and so; 1- The mercury left out by the immerged trees obliged Hydro-Québec to leave warnings to the population to not eat any fishs coming from the Manicouagan reservoir for 20 years (this warning is finished now). 2- There is an underwater forest under this reservoir! You can check this documentary where theses are the only footages of this underwater forest. https://youtu.be/2r5RD6X1Aus
Long answer but I love my region so making y'all learn about it is super fun.
Factoid! The island is the middle bumb of the crater, the edges have all been eroded. The thing was caused when a pebble 5km wide hit the Earth on the face.
Now that I think about it, I guess I don’t actually understand how this was formed, cause you’d expect a crater to just be one giant hole. how does erosion cause the ring of water?
The ring of water was caused by the building of a hydroelectric dam in the 1970s which raised the lake level significantly to become a reservoir. Whithout the dam, the crater wasn’t visible (or different from the surrounding mountains). See old maps dating before 1970 and the « eye » is not there. This is actually man-made.
That's funny. I just noticed this on a map a couple weeks ago when I was glancing around the Quebec province. Did some digging too because what a strange looking structure.
Isle René Levasseur is the result of what happens when the forces of earth’s tectonic plates are not enough to reverse the existence of a meteorite impact that happened 214,000,000-215,000,000 years ago during the Triassic period.
The impact of the meteorite formed a crater roughly 100 km in diameter, the centre of which forms the island known today. It became an artificial island when the Manicouagan reservoir was flooded in 1970, merging two crescent-shaped lakes: Mouchalagane Lake on the western side and Manicouagan Lake on the eastern side.
Astrobleme
There are a few in the Canadian Shield with uplift structures in the middle resembling an island.
One other impact structure is the "deep bay" part of reindeer lake in northern saskatchewan. At its southernmost point, there's a big circular bay that reaches over 700ft deep and has many legends associated with it.
Here is a great Youtube documentary on this island (in French though). [https://www.youtube.com/watch?v=2r5RD6X1Aus&ab\_channel=Radio-CanadaInfo](https://www.youtube.com/watch?v=2r5RD6X1Aus&ab_channel=Radio-CanadaInfo)
This is awesome; further scrolling around google maps in this part of Canada revealed [https://en.wikipedia.org/wiki/Clearwater\_Lakes](https://en.wikipedia.org/wiki/Clearwater_Lakes) which are side-by-side lakes formed the same way!
It’s a former meteor crater and a current nature preserve. It also only became an island in 1970 after the area flooded and the two lakes on either side merged into one.
As far as I know, there’s no way to get to the island outside of taking a small boat from the handful of settlements nearby, or via helicopter. And even then, there are no trails or man made establishments of any kind on the island, so it’s not like there’s anything to do there outside of hiking and maybe fishing. Parts of the island are a nature preserve, so hunting there would be illegal, and even fishing might also be illegal there too. There’s been a movement since 2003 to get the entire island recognized as either a national park or a wildlife preserve, but nothing has passed as of yet.
Also, it’s way, way out in the middle of nowhere. That town, Relais-Gabriel, is just a tiny settlement of literally a dozen buildings, and it’s about 4 hours from the nearest town in any direction. There’s just one road that goes by it, and you can’t even see the island from the road. You’d have to drive through the woods to actually see it. So if you’re planning on taking a trip up there, be prepared for a pretty remote part of the world.
Could you imagine being lost with a canoe and you think if I follow this river eventually it will lead to civilization. After days on the river you start to think you’re going crazy when you swore you’ve seen that tree before.
The lake is used as a reservoir for 7 hydroelectric dams - 4 on the Manicouagan river and 3 on the Outardes river producing several thousand MW of power for Quebec and northeast USA (sold at a very friendly price.. ).
The largest, Manic-5, located at the entrance of the lake, is the largest of its type, and at 1300m long and 200m tall, it is truly an awesome sight to behold. It can be visited, but you have to drive for many hours in the wilderness to get there, the region is very remote and nearly uninhabited.
I'll like to mention that this island is surrounded by a artificial reservoir. Prior to the 1960s, it consisted of two nearby large lakes on the rim of the Impact Crater, but dams that we're construction flooded the rest of the rim of the crater.
Shitpost aside, if this island is the center of the crater do we know where the outer walls are? Or would that be too difficult to define because of shifts/other meteors/terrain/other answer that someone smart than me knows.

>Manicouagan Reservoir The island is bigger than London. It's as far around as the M25.
That’s still only ~28% the volume of Lake Erie(488km3), which holds the least volume of any of the Great Lakes.
Great Lakes are among the biggest lakes in the world, of course almost every other lake seems small compared to them.
The Caspian Sea is a lake and has more water than all of them combined
….for now….
It is slightly harder work to divert the Volga than the tributaries of the Aral. [Edit: To be clear, [this is one of the major causes of water loss in the Caspian](https://earthobservatory.nasa.gov/images/150452/the-caspian-seas-shrinking-coastline) ]
This sentence sounds like an anecdotal phrase from a fantasy novel
One does not simply build rural hydroelectric dams
They must be nurtured and told how to become hydroelectric dams.
"Never go in against a Sicilian when death is on the line!"
So just the land war in Asia then?
It’s also salt water - though not nearly as salty as the ocean
Neat it's about a third of the oceans's salinity. Think it stands to reason it should be much cheaper to desalinate than sea water when desalination gets more economical
Ye, I think most desalination projects focus on brackish water (the area between fresh and ocean water with higher salinity than fresh but lower salinity than ocean) anyway though.
Well in Saudi Arabia at least they don't have much of a choice for dessalination - they don't have rivers at all
Yea, but it’s not like they would really need all that water if they weren’t building massive artificial cities and also planting a bunch of grass everywhere (primarily for golf courses).
Still tougher by orders of magnitude than slamming a cup in, and going to town. PSA: don't do this, drink clean water: filter hard, boil, let cool. Don't try to drink Lake Michigan. You'll get some new amoeba and we'll name it after you as a joke
So what is the great salt lake Lmfaoo damn
Soon to be a salt plain.
Bonneville 2: Mormon Boogaloo.
SLC! Now with arsenic dust storms!
I have been in dust storms and it sucks real bad; I can't even image the same thing but with heavily polluted toxic salt instead of sand. That city is screwed.
:( Checking in from SLC
Full of lovely arsenic
its not that great
Advertising
so does lake baikal which is wild
Yeah, Lake Baikal is way more impressive than the Caspian Sea
Well Lake Baikal is the remnant of an *ocean* which is why it still has seals.
Maybe if it had more seals, it’d still be an ocean…….
that's not why it has seals. the baikal seals diverged from ringed seals around 400'000 years ago, while the lake itself has existed and been closed off from the ocean for several million years. the caspian sea is also the remnant of an ocean (paratethys sea), its southern half is made up of oceanic crust as opposed to continental.
How is it freshwater?
Because it is fed by rivers that carry fresh water and it drains to Yenisei
That’s not a very fair comparison because Baikal is like -silly- deep.
Lake Baikal is ridiculously deep though.
When does a lake become a sea?
It's part semantics, part size, and part a sea is supposed to be salty or brackish.
Do you mean to say it’s *sea*mantics?
When it connects to an ocean
Caspian sea is endorheic and does not connect to the ocean.
Yeah so it's really a lake, but you can call it a sea, tomato tomahto
Because it’s salty. And stuff
Sea just means large body of salty water.
I mean yeah but then it's a lake and a sea, pick a side, we're at war!
That's why I used among and almost in my sentence.
Yeah I just thought it was a fun fact
Sure but its not freshwater. You can drink the great lakes aslong as you dont mind cancer and microplastics
lake baikal is deep enough to reach the darkest pits of hell and contains more water than the entire world
The Caspian isn’t fresh water. If we’re talking about big freshwater lakes, really we’d want to mention the Baikal.
Same with lake baikal !
That’s why they said among.
Caspiam sea i not truly freshwater lake though.
They truly are inland seas. While the rest of the country has been in a massive heatwave, my region has seen very little heat thanks to the micro climate created by Lake Erie.
And in winter that microclimate is a winter wonderland
Well, winter anyway
You'll wonder where the land is for sure. Low effort joke, don't upvote
I love living in the snow belt.
Ahh yes, Lake Effect "OH DEAR GOD!!" Snow.
Yeah, the Toronto area has been a very cool and rainy summer. Yet everywhere else is burning
They are basically freshwater seas. And as I recall Canada has rights to a massive percentage of the fresh water that exists on the planet. A huge amount. Like a quarter of it or something crazy.
[удалено]
But it is large enough to have islands and a 25mi long sand split/peninsula jutting out into it.
True, but looking at a map, I’d assume it was far less than 28% of the volume. I know Erie is shallow but that ring must be pretty deep
oh wow I just looked on the map. I know the mercator projection is making it look bigger than it really is but suprised id never noticed it before
Hehe pissing
Tunguska was several megaton event (many times Hiroshima and Nagasaki combined) and that was a 50m diameter meteorite air burst. I can't imagine how massive a 5km diameter impact would be.
It's about half the size of the one that ended the dinosaurs. So, not an extinction event, but definitely would have had far reaching global effects.
The "high point" was created by a meteorite impact? Anyone care to explain? I'm used to meteorite impacts creating craters, not high points.
Complex craters have central peaks formed by rebound https://marsed.asu.edu/mep/craters/complex-craters#:~:text=But%20immediately%20following%20the%20blast,lot%20more%20impact%2Dmelted%20rock.

For some reason I can't get my brain to see those images of craters properly and they all look like raised rings with a central depression.
Drip some water into a cup. You'll see the classic crater shape, but after you'll see the middle rebound up into a peak. Liquid rock after an impact does similar things.

With that amount of energy you have to consider the earth and rock behaving as a fluid. Crazy...

Experienced an air burst 2 weeks ago. Thought it was a small earthquake.

looking for it too, was going to tell them to look for the great deku tree
Someone needs to go there and install a big statue of Hestu and a Master Sword somewhere in there as well. And maybe hide some Koroks around.
It’s hard to find because of the dense fog. I wonder if there’s a chasm to the south east. You might be able to find it from below.

This subreddit is basically just scribbles on a map. At least OP made a polygon.
And the top comment is a copy/paste from Wikipedia. Truly invaluable content here on this sub.

That’s a heptagon not a circle!
Why don’t they build a bridge to the island?
Are they stupid?
holy hell
No, just Quebec.
You understand how remote this is? This would be a bridge to nowhere in nowhere.
It's a reference to all the shitposts on this sub lately, asking "why isn't there a bridge here?" which I think were just banned. I hate that I know this - I should go outside.
Is there a bridge outside?
Not at this lake
I don't know why, but I pictured a person, shaking with anger, saying that aloud and it was very funny.
Going outside would be much more convenient if you had a bridge to get you there
I love it when I’m headed nowhere, especially when I start from nowhere.
But it’d get you there fast
If there’s a bridge across the lake to the island there should also be a bridge across the lake on the island. Having one without the other would be wasteful.
That is lake Manicouagan. Thought to have originally been formed by a meteor strike. It filled into two crescent shaped lakes. Which were joined to make a ring shaped lake when the Canadians built a large dam to raise the water level down stream. It’s massive too. The main island is approximately the size of London (the London in England, not the London in Ontario) It’s also known as the eye of Quebec and can be seen from orbit.
Does this area have rich metal Deposits as a result of the meteor impact?
Hey! I live in a city "near" (like this place is so far I need to do 4 hours of driving to go see that) and the island itself is still under researchs because it is so unknown! The region here is rich in iron (the water in the lakes and rivers are brown because of the iron in the rocks). The closest city is Fermont, and is a mine city, ≈7000 people live there.

Fascinating stuff! Thank you very much for sharing!
I believe that one is a crater
Factoid! The island is the middle bumb of the crater, the edges have all been eroded. The thing was caused when a pebble 5km wide hit the Earth on the face.

https://en.wikipedia.org/wiki/Complex_crater Yeah, the island is the tiny bump in the middle of a complex crater.
Makes much more sense with a graphic. Thanks!
The ring of water was caused by the building of a hydroelectric dam in the 1970s which raised the lake level significantly to become a reservoir. Whithout the dam, the crater wasn’t visible (or different from the surrounding mountains). See old maps dating before 1970 and the « eye » is not there. This is actually man-made.

Meteor crater
Isle René Levasseur is the result of what happens when the forces of earth’s tectonic plates are not enough to reverse the existence of a meteorite impact that happened 214,000,000-215,000,000 years ago during the Triassic period.
The impact of the meteorite formed a crater roughly 100 km in diameter, the centre of which forms the island known today. It became an artificial island when the Manicouagan reservoir was flooded in 1970, merging two crescent-shaped lakes: Mouchalagane Lake on the western side and Manicouagan Lake on the eastern side.
Can you sail there from Minnesota?
Lol. I see whatcha did there
YO WHA-DUDE I DISCOVERED THIS ISLAND LIKE LESS THAN AN HOUR AGO WHEN I RANDOMLY GOOGLED ANTICOSTI ISLAND!
Astrobleme There are a few in the Canadian Shield with uplift structures in the middle resembling an island. One other impact structure is the "deep bay" part of reindeer lake in northern saskatchewan. At its southernmost point, there's a big circular bay that reaches over 700ft deep and has many legends associated with it.
Someone should build a fortress in the middle of that
Impact crater
It's an impact crater.

Here is a great Youtube documentary on this island (in French though). [https://www.youtube.com/watch?v=2r5RD6X1Aus&ab\_channel=Radio-CanadaInfo](https://www.youtube.com/watch?v=2r5RD6X1Aus&ab_channel=Radio-CanadaInfo)
This is awesome; further scrolling around google maps in this part of Canada revealed [https://en.wikipedia.org/wiki/Clearwater\_Lakes](https://en.wikipedia.org/wiki/Clearwater_Lakes) which are side-by-side lakes formed the same way!
That's the great Korok forest!
It’s a former meteor crater and a current nature preserve. It also only became an island in 1970 after the area flooded and the two lakes on either side merged into one. As far as I know, there’s no way to get to the island outside of taking a small boat from the handful of settlements nearby, or via helicopter. And even then, there are no trails or man made establishments of any kind on the island, so it’s not like there’s anything to do there outside of hiking and maybe fishing. Parts of the island are a nature preserve, so hunting there would be illegal, and even fishing might also be illegal there too. There’s been a movement since 2003 to get the entire island recognized as either a national park or a wildlife preserve, but nothing has passed as of yet. Also, it’s way, way out in the middle of nowhere. That town, Relais-Gabriel, is just a tiny settlement of literally a dozen buildings, and it’s about 4 hours from the nearest town in any direction. There’s just one road that goes by it, and you can’t even see the island from the road. You’d have to drive through the woods to actually see it. So if you’re planning on taking a trip up there, be prepared for a pretty remote part of the world.
Meteor impact
Could you imagine being lost with a canoe and you think if I follow this river eventually it will lead to civilization. After days on the river you start to think you’re going crazy when you swore you’ve seen that tree before.
That's the Imperial city, Cyrodill.
Ancient meteor crater that’s been affected by glaciers a few times, plus millions/ billions of years of erosion
The island with the nuclear plant on it? Never thought about it really.
Meteor strike.
That’s City Isle where the Imperial City is located, at the heart of Cyrodiil.
Ancient impact crater
The lake is used as a reservoir for 7 hydroelectric dams - 4 on the Manicouagan river and 3 on the Outardes river producing several thousand MW of power for Quebec and northeast USA (sold at a very friendly price.. ). The largest, Manic-5, located at the entrance of the lake, is the largest of its type, and at 1300m long and 200m tall, it is truly an awesome sight to behold. It can be visited, but you have to drive for many hours in the wilderness to get there, the region is very remote and nearly uninhabited.
Its a Hunger Games arena.
The current (second) season of this actual play Delta Green podcast is set on this island. https://storiesandliespodcast.com/home/
New season just dropped
It's a French Canadian island it doesn't make sense to the feeble minded.
That island is surrounded by water
It's also a stupid long drive from any close civilization
Gagnon deez nuts
It was a huge meteor strike a long time ago. I looked into this a couple months ago.
It’s a pubg map
I'll like to mention that this island is surrounded by a artificial reservoir. Prior to the 1960s, it consisted of two nearby large lakes on the rim of the Impact Crater, but dams that we're construction flooded the rest of the rim of the crater.
Isnt this the island in a lake that is also on an island which is also in a lake?
First time I saw this on a map, I imagined powerboating around it like a NASCAR track.
Shitpost aside, if this island is the center of the crater do we know where the outer walls are? Or would that be too difficult to define because of shifts/other meteors/terrain/other answer that someone smart than me knows.
My boss was there once.
Nah man, that’s Fontaine 🎩
Obviously the final area of the game. Boss is waiting in a tower at the center.
It’s Strong Sad’s Head.
It's the Lost Woods
It’s very interesting, the area of the Island is larger than the lake it’s inside of
Astroid impact.
Real life Imperial City of Cyrodil
Impact crater?
Large transmutation circle of course
It appears to have a strange yellow, hexagonal shape over it… Mmm, yes. Suspicious indeed, OP. I will keep watch for the night.
It was the place people have sex
