Brian Phillips : I don't mean to make light of your damage assessment, but from a land lover's perspective...that is so strange, and yet sooooo cool to watch! Thanks for posting the video!

Buz4rd : Holy shit thats some nice grass...

Boats Boats Boats! : UPDATE: -------------------------------- Since publication of this footage, shipping traffic has been slowed down and monitored by the US Coast Guard to ensure all vesels maintain compliance. This video was part of a series of videos studied and analyzed by the USCG to determine that the upriver vessels were traveling anywhere from 3 knots to 5 knots over the allowed 8 knot upriver limit (in this section) during the shipping season. Speed limits have now been enforced throughout the St Lawrence seaway, and the issues shown in this video have since subsided. http://northcountrynow.com/news/ship-speeds-seaway-cut-due-high-water-levels-0112566 SHIPPING TRAFFIC INFORMATION -------------------------------- Great Lakes Shipping traffic scaled up in the 1970s with the addition of the "seaway cut" at the entrance of lake St. Clair. This cut allowed larger vessels to navigate the great lakes, and the narrow connecting waterways (as seen in this video). Despite vessel size increases, commercial shipping vessels have coexisted happily with land owners. In fact, for nearly 100 years - shipping traffic and effects have been non-problematic in this region, due to vessels traveling at slow speeds through navigable waterways. However, recent technical advances in GPS and computer aided steering mean that large vessels raging from 500 - 1,020 feet in length can now navigate the waterways much faster than before. Combined with shipping companies placing increased time-pressure on vessels - this has lead to ships moving much faster than seaway engineers have planned for. Previously large taconite-ore carriers, such as the vessel shown, moved much slower due to human operation of steerage and navigation. While increased speed is good for profit, the negative effect is that faster speeds through narrow waterways cause an increased amount of "Tidal Bore" due to fluid dynamics and displacement https://en.wikipedia.org/wiki/Tidal_bore Even small increases of speed of only a few Knots can greatly magnify the effects of tidal bore exponentially (an increasint log when graphed) due to water being a "non compressible medium". The displacement effect in this video is being caused by a 1000' long Freighter heading northbound on the St. Clair river, running at 4 knotts over the allowed speed of travel early in the shipping season. INFORMATION ABOUT THE VIDEO AND ISLAND: -------------------------------- Many the cottages on Harsens Island have existed since the early 1800's, and all have coexisted, without issue, with shipping traffic happily. The small brown cottage in this video actually dates back to 1850 (with obvious structural modifications made over 150 years). This property in particular has been family-owned and is historically considered one of the original island cottages, with deeded family records dating back before Michigan declared statehood. Information on Harsens Island: https://en.wikipedia.org/wiki/Harsens_Island NEGATIVE IMPACTS OF INCREASED SPEEDS DURING 2011 - 2014 -------------------------------- Until 2011 - This canal used to be a breeding ground for numerous fish species such as Bass, Walleye, and Sturgeon. Ship traffic in the main channel wasn't a problem in the past, as strict speed limits on freighters was maintained. Due to the washouts created during this shipping season, the breeding grounds were eliminated - and the St. Clair river sturgeon is now considered and "endangered species" https://www.fws.gov/Midwest/sturgeon/biology.htm

joynthis : You wanted to live on the water. Shiposaurus says "here ya go."

4cooey : Well your going to have to start shooting at the ships, I see no other option.

Gurn Blanstein : The devastation was incredible!

Tug Speedman : It's kind of funny reading through these comments, none of which seem to come from anybody in the industry. The video is from 2011 when the Great Lakes were experiencing near record low water levels. As such the ships are closer to the bottom and squat down more at the stern and pull a suction on the bottom which in turn sucks more water in from the sides. Since 2014 the water levels are back up and the ships run the same exact speed but don't pull any more water so the damage is almost non existent. The funniest part is now that the water levels are back up, wait for it, the homeowners are complaining that the water is too high. 150 years ago there was a heck of a lot more traffic on the St Clair river going up and down, but the ships were smaller and, more importantly, people that lived there understood that they lived on a commercial highway and everything that went along with that (including steam whistles at 0230).

TexasGTO : I think there's a few spots for couple more bridges.

Breaking Toast : holy shit ive seen under water farts with more action than this video

Stephen Foley : You could have died! Reminds me so much of the 2004 Indian Ocean Tsunami (Recreation i did in my bathtub)

oldUmanUshea : "this canal back here will drain ALL the way down" Canal drains about a foot down.

Craig Case : That's why you keep your boat on a lift if you live on Harsons Island. 🙂

radio boys : ore boats have been going up and down the St. Clair River for over 100 years live with it or move

Hal VanSlyck : Uh... what damage? But seriously, I'd truly enjoy living in a place like this. "Watchin' the ships go in and watchin' them go out again..."

Michael T : Can't blame the train when you move next to a train track. What do you mean that "something bad will go on?" If you video taping this is a means to try to stop them from using a river, then you are wasting your time. Nobody is going to stop a shipping lane because one guy is unhappy with a little water.

C Tremble : Update: he bought a house 3 miles from the airport and now complains about jet engine noise

James Carter : If this happens every time, and has been for years.... then the people living there are just stupid.

Million Dollar : Fantastic your kids get free surfing waves at no extra charge get all the surfboard in the suit for the children and look at the bright side of it

Mazwell96 : omfg the absolute carnage caused was horrifying

Donnuts rsn : hook up a big ol net and see what you catch next time

specialtymachining : Or it may purge the slough. Something good could happen?

doktorbimmer : That's freakin awesome!!!.. have you tried to surf it yet?

MrBugsier5 : thats why you ask the Dutch how to build canals.......

evan fagan : rich white people problems lol, don't know how you dealt with it this long you poor thing

Jan Diehn : To a lesser degree this effect occurs when any good sized ship moves upstream. The ships of the great lakes were here long before these fancy houses. It is like building houses under airport approaches then complaining about the noise.

Matthew Foote : Those freighters have been running through there longggggggggg before you people decided to build your houses there. And yes, I know the area VERY well. This is exactly why a lot of the race tracks in S.E. Michigan have closed down too. People decide to build houses right near them.... then they squawk about the noise.

Nicole K : This kind of bore will also wash out the supports for the bridges, which, I suggest, is more serious concern.

Derrick Van : So who's to blame? The shipping lane? Or the idiots who build houses and canals next to them?

Matthew Slater : it would be interesting to know how many ships actually go past each day and week?????

Edward Barros : I think all shipping in the world should stop. Then his little canal can be saved.

jeremy western : Hogwash...that 1000 footer will NOT fit under that bridge

Batt Mann : Kinda like teachers complaining about their salaries. Didn't they know before hand????

Jodian Gaming : Welcome to life living on a shipping channel. Our inlet completely drains down to the mud before refilling. Actually a good thing in my case, it keeps the reeds from encroaching on the inlet and removes any sediment so I don't have to keep dredging it out. No speed limits have ever been set here.

Nermket : How much could it cost to line the sides with concrete or something? Sounds like a problem the Netherlands has already found a solution for.

dabprod : WOW, man I've never heard of anything like that. I've been up on the St Lawrence several times but was never at a canal. This is something you have to see to believe. That's dangerous. What if kids were in a small boat, canoe, or a kayak in the canal when that ship comes by.....? Or if ANYONE was in a small boat for that matter. Thanks for posting the video.

Brian Meyer : some stupid comments.. ALL BOATS are responsible for any damage caused by their wake. So if something was damaged the captain, ship owner would be liable.

sniper152 : If it's causing damage it seems they would build a gate that would stop the surges.

IronCross : Looks like Harsens Island in Mich. That has probably been happening for 70- 80 years. I wouldn't expect neighbors to close the canal.

James Monahan : That's pretty amazing. Thanks for sharing that.

Xs395 : Living on a glorified sand bank.

Stuart Coghill : Oof ouch owie my 1st world problems *wipes tears with $100 bills*

Jean-Philippe Boulet : Very impressive.

Johnny Stirstick : Wahhhhhhhh wahhhhhhhh gotta love full grown babies always looking for something to cry about. Adjust your tampon buds.

d texas : I'm sure the folks in Japan feel your pain.

Gilbert : You guys are gonna have some erosion issues.

Cigar Dave : I used to work with a girl who could drain fluids like that

goofyfoot2001 : I would personally be greatful I live in such a wonderful place

Oscar Muffin : That damage was truly incredible. I can't believe they would allow this to happen. Destroying all of that stuff in one go.

Bram Stolk : On the up-side.... Those waves probably prevent mosquito eggs from hatching. Free service from speeding tanker: no malaria outbreak!

T : next time a boat comes you should grab a board and surf it
