UPDATE: -------------------------------- Since publication of this footage, shipping traffic has been slowed to proper speeds and monitored by the US & Canadian 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 (land relative) upriver limit (10.4 knot water-relative limit) during the shipping season. Speed limits have now been re-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 engineered 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

Comments from Youtube

Buz4rd : Holy shit thats some nice grass...

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!

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

Gurn Blanstein : The devastation was incredible!

Mazwell96 : omfg the absolute carnage caused was horrifying

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

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

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

Pat McBride : Surf's up! They need gates.

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

Don Hall : plz read the entire post "ENTIRE" post before leaving an uneducated post

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

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

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).

Burr Anderson : The sea was angry that day my friend.

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

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

Ruben Delgadillo : The real story is whoever takes care of the grass does a hell of a job!

Harley Trader Jr : This video... is embarrassing. 2/10 should be raised into the next tax income bracket.

Rottler Property Services : And yes that is how water works. Thank you sir.

Ian 57 : Well cry me a river

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

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.

Kingtate55 : Why is there not any racial comments here? Boat lives matter too

HardiumGaming : You need to think positive. It's a surfing arena in your BACKYARD Duh!

Andrew Nichols : That happens naturally on the River Severn in the UK - it's called the "Severn Bore".

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

wingmanalive : The late George Carlin: "People build their homes next to an active volcano, then wonder why they have lava in the living room. "Build more prisons!!.....But not here!".

FOXBODY 351W : Go to a military surplus store to purchase an old German mine. That'll teach um.

cgcgundersen : That's some serious first world type problem right there.

Nopainnogain Hurts : Can you do more of these video I enjoyed that

theID2 : know what a windscreen is?

TheAtlantaWalkers : Doesn't look like its badly damaged? 🤣

Gammareign : Use that for small hydropower.

Tom Kazutara : Hearing Phil Swift's voice; "That's allot of damage!"

TheoBrixtonTheKid : Damn I wish I lived somewhere like this so I could share your frustration, must be nice.

Erik Perik : In German we say "thousand-footer" for centipede.

Luc Williams : @bengravy score this bro!!

Ed B : Did you fast forward when it drained all the way down cause I missed it. You also forgot to film the huge wave coming back. Other than that pretty cool!

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

Jeffry Gilbert : Capitalism! Live with it! How DARE you insist those ship owners slow down! Just WHO do you think you ARE!

Xs395 : Living on a glorified sand bank.

Keepit real : Why live and build house next too a major shipping lane then complain

Bobby Patton : shouldn't there be a weir at the junction of that and the river perhaps?

Kevin Boulware : Jesus.. You're a drama queen! "Damage to the boat" - the boat that is resting on its hull in your yard... LOL

Cale Cadman : Soooooo y'all moved here and the sellers never mentioned the giant ships going by, or you didn't see one while you were looking at the house? Cause I'm sure no one living there now was there before the shipping route was created.

Steve Degenhardt : Ships,boats are responsible for damage caused by their wake....

Gilles : Holy shit where and how you live is amazing.
