I’m fairly certain trenches people dig from bodies of water to the ocean create riptides. Which is why it probably wouldn’t really be that fun, and why it’s illegal…
Lots of crossed currents so you can't properly swim or even float, and enough sand in the water that you can't open your eyes, and if you do, you still see nothing.
Yes, this happens naturally at times for sure when heavy rain causes a river to breakthrough to the sea, but unfortunately, many people have started instigating this event by digging. While rad, it can be very harmful to the local environment/ecosystem.
Yes, but this is a little different. Think of lagoons as ponds. While the lagoon can connect to the ocean, usually there is a small natural berm between the two. That berm is usually built by the ocean deposting sand, and even if it's pulled away by high water or human intervention, they are quite naturally regenative.
Usually, during very tides, the water levels in the lagoon, and in the ocean, get high enough to meet again. People take advantage of helping the lagoon "empty". That creates this natural water slide of sorts that were watching the guy float through in the video.
The lagoons don't fully empty, as the lagoon bottom and the ocean are both lower than the lowest point of the burm washout. Then over the next few days, the ocean current moving the sand will naturally rebuild the burm, and the cycle starts over.
I hope I explained this well. It can be a hard thing to imagine.. if not, and a full visual would help,
I found a video of my local lagoon emptying, that shows the high point between the lagoon and the ocean. Here the link :)
My understanding is this pretty much needs to be done periodically. A lot of these “rivers” are build ups of storm water run offs and leaving that much stagnant water with no where to go can lead to bacteria growth and pretty nasty ponds.
There are plenty of spots where streams and small rivers come out on the sand at the beach. Pretty common in the Pacific Northwest where there's a mountain range right up to the coast
I'm just on the other side of the Coast Range in the Willamette Valley. We do be getting runny. Got pretty wet last week. You are correct. Tons of streams and rivers flowing out on the beach
Edit: to all of you saying is there a study? Or how do I know? Giant erosion and changes to water way structures are nearly always damaging to the ecosystem. Go use Google or your favorite AI to get an answer.
Genuinely never seen such opposition to something that seems kinda obvious. Like, yeah changing the environment has an effect on the environment. If I kill a tree, that has an effect on the environment. Doesn't matter that the tree would die anyway, I had an effect on the environment, regardless of how small.
Some places it's an annual event where it's going to happen and people just accelerate it, and then surf it. Other places it's illegal and is causing erosion issues, but people still keep doing it.
Got a source for that? Because I seem to recall the story behind this vid being that this is something that happens naturally every so often, and these guys just helped it along and made it happen faster by digging out a channel so they could create waves to surf on.
https://www.reddit.com/r/askscience/s/W2a0zte8IC
Its naturally occurring and only takes months for most of those sand dams to rebuild themselves. I know on place in Hawaii as a large gathering of surfers every year when they get ready to connect the river to the ocean
Lol. What on earth could I possibly have to gain by being dishonest about how I recall a backstory for a random video of dudes surfing in a trench they dug?
This video has been around forever, and that's genuinely the backstory I recall hearing. I'm not saying that IS the backstory, just that that's what I recall, which is why I asked for a source from the previous commenter. My memory is fallible just like everyone else's, so I could be totally wrong.
I'm not sure but I don't think it is. The 'lake' seems to be the effect of water getting trapped during the transition from high tide to low tide due to elevation changes.
So there’s a little stream that pools at a place called the lions den in grafton county in Wisconsin and it is like 9 feet away from lake mocghigan downcoast from a coal plant and once there was a baby fawn and it was bloated and dead in there and lots of dead ale wives when they die off in the masses and college kids once dug it open to pour into the lake and it was icky
Also o think little fish were having a hard time getting sucked out? I kept finding them getting stuck in the pebbles in the makeshift waterway and threw them back into the stale pond thing from the clay stream
Beavers flood existing areas and create new ecosystems often. And yes it can be destructive to some ecosystems but not to the same degree. That's much different than causing mass erosion and removing a potential ecosystem.
So would this be dangerous? It looks fun but I also feel like currents and stuff would pose a huge risk. But like, I can kinda surf and I'm an excellent swimmer. I live next to the ocean even, but I wouldn't do this and I've never seen anyone do it.
Wear neoprene so you’re floaty. Ride the rip current out as far as you care to. Swim parallel to the beach to get out of the rip. Once fully out, swim (or bodysurf!) to shore. Repeat steps 1-4 as necessary. Your swim skill and endurance will determine the safe limit of step 2, your competence at step 3 will determine the risk of you accidentally exceeding that limit. Do keep in mind that the rip will eventually take you out to where it dissipates and another current is stronger, potentially taking you . . . away. Be aware of prevailing currents.
Instructions unclear....I am now in the middle of the ocean and I can hear a voice telling me to "CONSUME" That is all it is saying nothing else and I am concerned....please send help to these coordinates
Aireys Inlet (the town where Round the Twist was filmed for those familiar with the show) lagoon sometimes breaches out to the ocean. Tried to take a Kayak out there one day when it was breached. Could immediately feel the loss of control from the sheer strength of the current once I got towards where river met sea and I bailed. It's scary shit lol.
Yeah... No it isn't. I live in the PNW and I've seen streams on the Pacific Coast that drain directly onto a beach with no alluvial plain (there's very little sediment in the water since the mountains are so close to the coast). Look up a place called Moclips if you're curious.
This was a couple of idiots who dug an artificial canal through a dune to connect a pond that was right next to the beach to the ocean. What you see is that pond rapidly draining, not a natural river. Been a while since I saw the original video but I think they got in some trouble.
Yes, this is not what's happening. A real river mouth would have washed all the sand away and be down to bare rock, silt etc.
These lads have created this by digging away between a water source and the sea. Its not as dangerous as other commenter are saying cos there probably not much power behind itm
Yeah but unless it's an endorheic basin that lake will eventually drain out into the sea, I'd say the majority of rivers do end up in the sea eventually even if they pass through a lake/lakes/wetland/etc. before ending up there
Actually editing this because upon re-reading that comment they said "all rivers" which definitely isn't true so yeah this comment ended up being a kind of net zero contribution to the discussion
That looks terrifying.
Yeaaa I’m not willingly dealing with dueling tides
But it looks so fun though.......
Legitimately looks super fun up to the part where you die at the end
But that's the best kind of life, right?
That's right, you only live once! .....thus you only die once☠️
That's not necessarily true!
I see where you're going with this, Reincarnation! See you on the other side!
Nahhh More along the lines of defibrillation
NO ONE'S COUNTING....
Until you can't escape the undertow
In a controlled environment, maybe.
And these types of wave slides definitely exist, I've seen them at water parks.
The lack of potentially fatal undertow is definitely a plus.
Maybe it would be fun on a board, but I'd be panicking about the potential undertow.
IF YOU LIKE DYING
It does. Anytime water is involved, Reddit pisses its collective pants.
I’m fairly certain trenches people dig from bodies of water to the ocean create riptides. Which is why it probably wouldn’t really be that fun, and why it’s illegal…
Flowing water like this can be very unpredictable and should be avoided if you care about not drowning.
It is as dangerous as it looks.
Lots of crossed currents so you can't properly swim or even float, and enough sand in the water that you can't open your eyes, and if you do, you still see nothing.
It is terrifying.
It looks fun to be honest but I'd really want a life jacket on just in case.
Didn’t these lads dig that out themselves? It’s on a beach if I remember right. Not a natural river.
Edit: the video https://youtu.be/3dnk6DCMjaM?si=N_GJIsxG4eR_yVpa
Yes, this happens naturally at times for sure when heavy rain causes a river to breakthrough to the sea, but unfortunately, many people have started instigating this event by digging. While rad, it can be very harmful to the local environment/ecosystem.
I dont get it. Isn't rivers flowing out to sea the default?
Yes, but this is a little different. Think of lagoons as ponds. While the lagoon can connect to the ocean, usually there is a small natural berm between the two. That berm is usually built by the ocean deposting sand, and even if it's pulled away by high water or human intervention, they are quite naturally regenative.

Oh ok, it makes sense if it were a coastal lagoon. We have one of those nearby.
Excess water in the lagoon is coming out one way or the other, either under the sand or over it.
This is talking about moving the outlet of water. Rather than creating one entirely.
My understanding is this pretty much needs to be done periodically. A lot of these “rivers” are build ups of storm water run offs and leaving that much stagnant water with no where to go can lead to bacteria growth and pretty nasty ponds.
There are plenty of spots where streams and small rivers come out on the sand at the beach. Pretty common in the Pacific Northwest where there's a mountain range right up to the coast
I'm just on the other side of the Coast Range in the Willamette Valley. We do be getting runny. Got pretty wet last week. You are correct. Tons of streams and rivers flowing out on the beach
I live on the coast. Can confirm.
Yep, it can be really disruptive to the ecosystem
Edit: to all of you saying is there a study? Or how do I know? Giant erosion and changes to water way structures are nearly always damaging to the ecosystem. Go use Google or your favorite AI to get an answer.

Funny. Speaking about ecosystem disruption yet telling someone to use AI🤔
Do those two cancel each other out?
Got a source for that? Because I seem to recall the story behind this vid being that this is something that happens naturally every so often, and these guys just helped it along and made it happen faster by digging out a channel so they could create waves to surf on.
They ripped a sandbar in half that emergency services used to access the rest of the beach. This isn’t natural…

/r/confidentlyincorrect
Bro they got a fucking fine for it due to damage to the ecosystem.
/r/confidentlyignorant
So many bros here saying "Sauce?" and missing that these happy numbskulls did this themselves and got fined for it.
So there’s a little stream that pools at a place called the lions den in grafton county in Wisconsin and it is like 9 feet away from lake mocghigan downcoast from a coal plant and once there was a baby fawn and it was bloated and dead in there and lots of dead ale wives when they die off in the masses and college kids once dug it open to pour into the lake and it was icky

How so?
Is there a study proving this?
🙄
So are beavers. Nature does what it does, it's always changing. "Destructive" is in the eye of the beholder.
Beavers flood existing areas and create new ecosystems often. And yes it can be destructive to some ecosystems but not to the same degree. That's much different than causing mass erosion and removing a potential ecosystem.
Comparing the two is a false comparison.
It's not a false comparison, they are both natural events. You're making shit up at this point.
What am I making up?
I'm not interested in your head canon.
ragebait used to be believable
Saw a lot of this in internet.
This is what Carmel River Beach in CA looks like when the rivers up.
Waiamea Bay in Haleiwa has this. Also in Kauai there's one at Tunnels.
Coastal dune lakes exist
Looks like a suicide mission
Ye you couldn't pay me. I'd be out asap. Water is no joke
As a white water person. I'd throw a grandad in there if they could swim 100 yards with a life jacket own.
And they were never seen again.
I do love a happy ending.
rip tide has entered the chat
the correct term which is rip current has entered the chat and replaced rip tide
incorrect term rip tide cries a little
undertow comforts rip tide
it’s really not spelled untertoe?
It's going to tow you to the bottom of the ocean.
It doesn't have toes.
I guess I was thinking it’s also lower and so is my toe… but there’s also the whole “under” part that clarifies that
Undertoe is the ground
Underto, like potato.
rip tide pride died, cried
Damn girl, you just go around commenting with that account? Good on you for living your life.
Yeah I'm too lazy to have multiple accounts 😅 might as well just let my freak flag fly.
Yeah this is suuuuuuper dangerous unless you know exactly how the tides are behaving that day
Sea people? Shit not again...
About to be very unfun very quickly
loads of rivers dont look like that, this is one of those where a sandbank was breached for surfing,
See the line where the sky meets the sea? It calls me.
If i go, there's just no telling how far I'll go.
So would this be dangerous? It looks fun but I also feel like currents and stuff would pose a huge risk. But like, I can kinda surf and I'm an excellent swimmer. I live next to the ocean even, but I wouldn't do this and I've never seen anyone do it.
Explain it to me!

He will end up in the sea, and in the sea, can swim normally.
Current just force you in a direction, it is generally a very bad idea to try to go against it, but you can go perpendicular to it.
Now playing Undertow by Tool
Sea men?
That is a really stupid thing to do.
Aireys Inlet (the town where Round the Twist was filmed for those familiar with the show) lagoon sometimes breaches out to the ocean. Tried to take a Kayak out there one day when it was breached.

Ir how to drown in one easy lesson
“And off you go”
“Weeeee-“
And that was the last time we heard of him
"And that was the last time anybody saw Andy..."
I'd do that once.
Yep, once is all it’d take.
And he was never seen again
Yeah... No it isn't. I live in the PNW and I've seen streams on the Pacific Coast that drain directly onto a beach with no alluvial plain (there's very little sediment in the water since the mountains are so close to the coast). Look up a place called Moclips if you're curious.

Bet that rip current was fun to swim out of..
Don't all rivers open to the ocean?
Yes, this is not what's happening. A real river mouth would have washed all the sand away and be down to bare rock, silt etc.
These lads have created this by digging away between a water source and the sea. Its not as dangerous as other commenter are saying cos there probably not much power behind itm
My local river outlet looks similar to this, but they added concrete on the sides to stop erosion.
No? Many flow into lakes
Yeah but unless it's an endorheic basin that lake will eventually drain out into the sea, I'd say the majority of rivers do end up in the sea eventually even if they pass through a lake/lakes/wetland/etc. before ending up there
Actually editing this because upon re-reading that comment they said "all rivers" which definitely isn't true so yeah this comment ended up being a kind of net zero contribution to the discussion
A lake is just a very small ocean.
That looks fun
This is too terrifying to watch.
You at least need a life jacket
i love the last past the most. Death.
He dead
And we never saw them again...
Total dick head move tbh. Destroying a beach and natural habitats for you to have a couple hours of fun is beyond shitty.
My water people need me..
Welp. He's dead.
Where I live, that river mouth would be teeming with sharks.
Does it always have a guy floating by?
Weimea river?
Nope.
These people dug a pathway from a lake,I think.
It started quite small then it grew and grew and in to this monster.
When I have seen these happen they are rain water drain ways that have backed up because of the sand.
They need to build this as a ride
Where the riveeeeerrr…. Meeeeeets….. the allllmiiiightyyyyyyy seeeeeaaaa
AMF
That's a big NOPE for me
Aliso Creek Beach OC, CA
Oh hell no
Yes but no
Where the river meets the ocean are Very dangerous currents to play in.
See you in China
I would probably pay to go on that ride.
And was never seen again
Thats Cool
Vent
What if you were laying on a surf board though?
Augustus Gloop!
Man the way people underestimate the power of the sea is wild— that flow can sweep you out hundreds of yards and fast.
Very dangerous to do this if not a super strong swimmer.
No "supper strong swimmer" can go against it, even olympic champion.
But to be fine, it just need to be intelligent, keep your calm, and be an average swimmer.
Let the current carry you to the sea, then swim to the side to not longer be in the current, then swim to towards the beach.
This gives me anxiety.
These guys dug this and it was just a little trench, the last several yards, and it turned into this, and I think and got in pretty big trouble, IIRC.
So…how does he get back, exactly?
It looks like fun! It would not really be dangerous aslong as you know how to swim
Aaaand he's gone!
Super chill waterslide with a side of drowning.
Thats a manmade ripcurrent lol
Wanna die?
Sacrifice to cthulhu has been made!
WOAHH THAT'S SO AMAZING!!!
You literally took this from top posts of all time
Looks more like ai slop
It is not ai slop. This is a thing.
A somewhat old thing I believe, I’m pretty sure I’ve seen the original video where they dig the trench that becomes this for at least 3-4 years
Yup. I’ve definitely seen it for 3-4 years now. There’s a YouTube video with the whole dig
Ai slop
This ai?
No, predates convincing video generation.
