Thanks for posting this!

Keyshell I am looking for this comment/answer because i want to punch those fucking Idiots,if they just do it just for fun...

Keyshell Thanks for posting this. I was wondering about the after effects of it! Good to know there wasn't any harm to the ecosystem

Keyshell where's the proof? show me you sources!

Chaos Order The proof is in the description. Look it up.

Maverick Quartero They think Waimea is somewhere in Africa where water is so sacred.

IAmGunzNoob No its because the UKposts Environmentalists saw the one thing that enrages them. Human beings having fun. Fuck em, they're cultists who think humans are a virus.

quantumbits it's not a lake. It's an actual river. They are digging where the mouth of the river usually is, but got blocked off by high surf. The sand is removed throughout the year by the state to allow the water to flow into the ocean.

quantumbits I hate to restate this again, because it was in my original comment. The Waimea RIVER is supposed to flow into the ocean, but it was dammed by sand created by the high surf. Once again RIVER, not lake. The Native Hawaiian species that live in the lower region of the river, like exactly where it was draining from, naturally spawn in brackish to salt water. They basically opened a dam that was not supposed to be there.

+Maverick Quartero Rivers close naturally to the sea all the time - this includes when high surf dams them with sand (like you said). Ergo, that dam is supposed to be there. This could remain closed for a number of years, and the water would still remain salty. All rivers (and most coastal lakes) eventually run into the ocean, and this likely would have opened eventually by itself, but its not really good practice to go an open every coastal flowing river just to surf when there's no swell. These types of rivers (in Australia at least) are called Intermittently Closing and Opening Lagoons (ICOLs), and they serve a great purpose in diversifying fish DNA. As fish are trapped in the ICOL when it closes, they breed for sometimes up to years creating new genes and adaptations to those particular conditions which once the ICOL opens those new genes are released into the general population of fish. Councils often artificially open lagoons like this, and you can safely bet (in eco-wise countries anyway) its not done without environmental consultation. I'm not saying they're causing great damage by any stretch of the imagination, but I think you're pushing your agenda without knowing/listening to all the facts. And it really is as simple as, if you're changing the environment, it's going to have an affect on the things that live in it. In freshwater ecosystems, damming water for water supply (and of course allowing water out for the river downstream of the dam wall to exist) is called river regulation. This is a well studied affect of altering ecosystems, and it most definitely results in a drop in biodiversity - world wide. This isn't as simple as "greenies" not wanting people to have fun.

Aaron Horrocks lol that's so stupid, you should still do it though

ya with good reason

***** damn dude that sucks for italy

Yeah makes sense, the government wants us to pay for there wave pools that use machines. Fuck the police. I'd love to try it where I live in Australia though because our waves aren't that great.

Vinny V OMG, idiots in video destroing ECO system of the river .

Luigi Urquico thanks for the heads up :D xD

Luigi Urquico If only I saw this warning 4mins and 45sec earlier... X_X

+Lui Angelo TAMO AQUI DIRETAMENTCHI

+Lui Angelo IT BURNS, IIIITTT BBUUURRNNSSS

Lmao

write your assemblymen. more surf!

Got tornadoes? I have surf board. Do you know Noah...I got a surfboard. Do you have Haarp machine, then you have flood and water....I got surf board....Hehe...

damnyell101 Its written in portuguese in the description. This is the Waimea River in Hawaii, almost every river flows to the sea a way or another.

same question?

damnyell101 This river naturally flows into the ocean at the right time of the year mate. What they are doing isnt too harmful

Any river near the Ocean flows there eventually, they create so called "Deltas" there. A Delta is something where the river transports sediment into the ocean, the transported material forms the Beach you see in the Video. A River changes course very often in those deltas.(Often in a timeframe of 1Million years and more). So no Problems environmentally, they disrupt the River and the very end and it is likely that sometime ago the river would have gone along that very path anyway. Hope i could help.

Every winter on the North Shore of Oahu the high surf dams the Waimea river-mouth with sand, and the heavy rains flood the valley. To counter this they have to open it up and since it creates some nice waves, surfing it has become a yearly tradition over there.

I don't care about nature I care about fun

That's why we are killing this earth. How do you expect us to survive?

While catching an awesome wave, that's how.

no, probably not. In fact even if the river is also salt water, with the amount of water being drained from it, that means another part of the river with a stable ecosystem will now suffer as less water will reach. But hey, small price to pay to go surfing for a few hours.

Chris X Actually, by the little difference in the height of the river and the ocean, im pretty sure its going to fill back up at night when the level of the ocean rises.

alex zannettou Yes, they do this every year

Chris X Dude, this happens many times a year. It self fixes. Get your fucking facts right before anymore sewage comes out of you.

all they had to do was dig a little tiny trench between the ocean and the river to cause that to happen. surely it happens on it's own when the tide is high

midomi

I think the river evens out before that happens but you can see it does get wider and wider throughout the video, until you see the water rushing begins to die down....

+Nitrobucket it will go back to normal with the tide

a year before natural flood by higher tides

Para nada

yup sure did that was a fucking shark haha

Naytheen Vanrooi Looked like his shadow to me lol

That's his shadow, moron.

ReliableMyke Def not a shadow. you can see the dudes shadow before 2:22 but there is a white looking thing that passes him then a dark looking thing neither are his shadow.

Other than his shadow that appears first and once The first grayish one was a shark and the second darker under the water looks like a sting array

The large swells of the winter in Hawaii cause the rivermouth to be damned up with sand which floods the river. The river eventually let's out on its own so by them doing this it doesn't impact the beach. This beach has looked the same for the past 50+ years. There's no harmful impacts

Do you know that the river does this naturally every year so this makes no difference?

+Kaipo Fitisemanu He was sarcastic i think XD

Anubis7169 dieded?

Anubis7169 they will be remembered as an hero

Anubis7169 For the people saying this is damaging to the ecosystem... this is a controlled breach approved by conservationists. The river is naturally blocked every year by sand dunes which causes the valley to flood and fill with water. The river will eventually swell to top the dunes and create its own breach. This is just doing so in a controlled manner.

Anubis7169 Who cares 90% of the native species in Hawaii are gone.

+58cedrick Ever heard of sarcasm? He was obviously commenting on how dumb the enviromentalists sounds like :P

The Waimea River naturally damns up with sand every year, and even without human intervention the sand damn eventually breaks and releases the water. By digging to get it started on a particular date this just ensures that surfers can enjoy it instead of it happening when no one is there to appreciate it.

Nathan Peck I have no knowledge about this, so thanks for clearing it up! But how does this happen? Naturally breaks and releases water, then naturally dams up again? Does the river start getting too "high" and start releasin water? How does it dam up again?

The winter tide and storms push the sand up into the entrance to the river, damming it up. Eventually rainfall causes the river to fill up to the point that it spills over the sand dam, and the water spilling over erodes away the sand, and it all washes out exactly as in this video. These guys just dug a notch to start the dam break early, during a convenient time for surfing. If they didn't do so it would have probably washed out some day when it was raining and the river spilled over the dam naturally.

Am sure that during the months that the river is dam, fishes come up to breed so by removing the sand out of the rainy season would definitely alter the ecosystem which could probably lead to loss of species.

Guys, just leave nature in peace! There are so many nice places to go surfing, you know? I did read many comments here and there...still think that it's a disaster caused by them, sorry...and if it gonna happen anyway wait for it then!

Drains every year as a part of a natural process anyway. Sand washes ashore during winter months and creates a natural dam. Nice try though. blog.swell.com/post/waimea-river-surfing

It would like to drain naturally. In a way that nature designed. The problem is, some people have decided that fun is better than natural.

+Roy Gould those people being nature conversationalists. They're actually preventing harm to the local ecosystem that flooding would cause with their intervention. Focus on an actual issue rather than fabricating one to satisfy your information.

I have seen the aftermath. The sudden influx of silt and fresh water into the bay killed a lot of sealife. You will never admit the truth and the moron who thought this up is the wrong kind of conservationist.

Ahh you fool. Anyone who has been to Waimea should know that all of that water is salt water from high tide with some potential rainfall.

***** Gee your're so bloody original. Let me guess 15 years old?

***** It's a very wasteful act for short term fun.

Not being a smart-ass but you do realize all's they did was divert a current, the current still ended up back in the sea. It's still being pumped back into the sea.

Jimbob how is it wasteful? Enlighten me

Zalgoret Warlock How the hell do you divert a current? Think about it for a minute.

in what way

Lmao how?

connecting a river so a sea

だとしても、自然相手のスポーツであるからこそ、自然な状態を人間が無理やり変えるのはいかがなものかと思うけどね。
