And he did a (2 part?) Video about the Orville Dam, how it happened and what was done after the incident.

[@CRneu]

The movie Damnation also takes a deep look at the history of dams and the issues going forward with them, also the hypocrisy surrounding their uses. It's a bit dramatized so be aware of that, but it talks about the issues with dams like few other sources do. For instance, Damnation says there are over 200,000 dams in the united states which is a bit high. But this video we're watching now says 91,000. This difference is based on what you define as a dam. The number is likely somewhere in the 150,000 range if you include all the seasonal dams.

Small but happy correction: the Lake Hodges dam recently completed a full year of repair work, upgrading its rating from "poor" to "unsatisfactory." The region is planning to replace it with a new dam 100 feet downriver by 2034, and in the meantime have allocated resources for ongoing maintenance.

[@karmacrackdown]

@@altrag I don't disagree, but from what I understand the design was too old to make the rating any better. The new dam is promising, and the danger is now at least less imminent than before.

@@Eagle3302PL "Already in progress" is at best 11 years away (per OP) - assuming there are no delays which is always a bad assumption with large infrastructure projects. That's a very long time to be running on "minimal maintenance". @karmacrackdown's response that the dam is too old to get a better rating is what it is. I don't know the details of why that's the case but I know its not uncommon. I can only hope for the sake of everyone in the area that that's entirely due to modern requirements being more strict in ways that can't be retrofitted, and not due to them performing "minimal maintenance" on what they've got.

I have immediate family who live directly across from the Edenville dam. I remember staying up late that night texting / calling them after the evacuation notice was given. It was one of those real-world instances of “what would you take with you in an emergency?” They were fortunate enough to be unaffected by the flood but many others were not so lucky and that summer we (the communities of Edenville / Sanford / Midland) spent our time working through the cleanup process. Seeing how everyone pulled together (especially the flood victims) and went out of their way to help others was very impactful and humbling. I’m glad that this and other dam disasters are receiving more publicity thanks to your video; keep up the good work.

[@StarWarsGirl2011]

I grew up in Sanford, so starting this video and seeing Wixom Lake immediately had my attention. I vividly remember the day the alerts went out that the dam was going to fail. Literally my childhood nightmare, having lived across from the Sanford Lake dam my entire childhood. It’s still so weird seeing those lakes today, or at least where they used to be. Just rivers now and completely overgrown, with boats still stranded in the dirt.

[@IONull]

My grandmother lived on a canal off Wixom lake. She fortunately moved a few years prior to the break. Spent MANY summers on a pontoon boat cruising the lake. Many 4th of July shows anchored off with many others watching a 360 show. Times spent buying candy and pop at the marina. There was even a restaurant where you could dock at and get pizza, never actually went inside it because my uncle was a paraplegic so we just got a pickup order and ate it at the dock. There was a small long island where people would anchor off of and go swimming. That was super cool to explore, a lot of driftwood and vegetation which housed all sorts of small creatures and other things which for a young curious boy was absolutely amazing. Met a lot of wonderful people out there too. Edith was an old women who loved going out on her little boat and going fishing; she also had a lovely garden. Grandma once drove her lawnmower into that canal taking out a few year old sapling. She wasn't allowed to mow the grass after that.

That tragedy, and the more recent Brumadinho failure were both caused by static liquefaction - same as Edenville in the video. The mining company at the time was warned that their dams were insufficient, but chose not to do anything... After those tragedies, along with the Mount Polly failure in Canada, the industry is starting to care much more about managing the risk associated with these dams. One company I've worked with has committed over $500 million to improve just one of their dams after we outlined the current risks of their facility. Sums of money like this would've never been spent just a few years ago.

[@bluetyphoon2100]

Dams should be treated much like nuclear plants in the way they shut down. If an operators license is revoked then they should immediately begin draining water levels and decommissioning the damns. Unfortunately everyone wants to squeeze every last penny and eventually it will cost life downstream.

[@macattack5863]

That's the real solution here.

[@Spencergolde]

I think a really tricky difference is the development that occurs downstream of a dam. You literally can't drain it without flooding tens or even hundreds of permanent structures built in the eventual flood plain. There's a cost of displacing people when the dam is being built and then another cost of displacement when it's being decommissioned

[@macattack5863]

@@Spencergolde You couldnt release the dam all at once but their should be a drier some extra capacity in every waterway to slowly drain a dam. If not those homes are going to be destroyed no matter what and should never have been approved.

[@bluetyphoon2100]

@Spencergolde absolutely. Everything down stream is more important than the dam itself. However, none of it will exist if your dam gives out. You do have to weigh the costs of the weight of water. Pour out maximum flow capable for everything down stream to survive. I'd argue sacrificing some to save all is a considerable option too.

[@bluetyphoon2100]

@Spencergolde to add, if they didn't run dams into the ground for economic purposes they would begin decommissioning years in advance and slowly drop water levels safely. Like a nuclear power plant.

When the TVA was established by FDR, a whole chain of Dams were constructed in my area. They actually used airplanes to survey the land and find the best geographical place to build it. Dad found a lot of those photos online, and scarily, the place I live now, my family’s home and only property for generations, was among the areas photographed. I still live here, since my area wasn’t chosen for flooding, but to think that my family could’ve been ousted from where they lived on a whim and forced to relocate; property is a major source of generational wealth, and it’s just plain peace of mind and stability, knowing that your descendants will always have a place to live, so the fact that all of that could’ve been taken from them, and was taken from so many people in my area, is really scary. One of the places that was flooded was an old logging town, and one of the only parts of the town that survives now is the graveyard. It’s on a big island in a lake now, and families yearly take a ferry ride and a long, multi-hour hike just to visit the graves of their ancestors. Obviously dams aren’t all bad. One of the ones in my area was built during WWII to supply power to an aircraft factory that was being built alongside it. The amount of good that they’ve done cannot be overlooked or ignored, but I think that, as for any nuanced, well-rounded analysis of history, the amount of bad they did, or if you want to think of it in another way, the amount of sacrifices made for the greater good, has to be mentioned and recognized as well.

So much of our public infrastructure is in this same state. Part of the recent inflation surge is due to railways closing down older lines and not replacing them; reducing capacity at a time we need it to increase. Highways are deteriorating rapidly because nobody wants to spend the funds on maintaining them, even as traffic on them grows and grows. Power outages becoming more frequent as grid operators refuse to upgrade and modernize equipment. Municipal water and sewer breaking down from lack of maintenance. in another 50 years, i expect we'll see internet services begin to suffer the same problems. the only reason it hasn't already been a huge problem is that the technology behind data networking is advancing rapidly enough that everything still gets swapped out on a semi-regular basis, but that will change as the curve flattens out and we approach a steady operating level.

There were four dam failures that day. The secord dam failed first, leading to a small lake of water flowing into smallwood lake, which made that dam fail, so then two lakes worth of water spilled into wixom lake, causing that dam to fail, then three lakes worth of water flowed into sanford lake, causing sanford dam to fail.

The fact that private entities can build these dams then essentially just abandon them once they stop being profitable is absolutely batshit insane. Profits are down, so this entire community can now live in increasing risk of being flooded out and drowned.

The one in Michigan tried emptying because it wasn't worth fixing, but the people who owned land bordering the reservoir took them to court to stop it because it would mean their lakefront property would lose its lake, and therefore property value. So they were banned from generating income by one agency, and banned from closing by a court.

Same thing goes with coal mines and oil/gas wells. There are a bunch of abandoned mines and wells, especially across western PA and Appalachia. The abandoned coal mines are particularly troublesome because they can flood and spill toxins into local communities and bodies of water. The Biden administration’s infrastructure bill has devoted a lot of money to filling and capping these mines and wells, but it’s very widespread, and it’s not something that should have been able to happen to begin with.

[@BuddyTobyTV]

Dam engineer here. It’s good to highlight dams but much of the content seems overly alarmist and gives the impression “dams are bad”. However, many of our largest cities rely on dams for their drinking water. 40% of our food comes from the California Central Valley, irrigated by water from… dams. Also safety and standard of practice has never been better. Yes dams are old, but those charged with keeping them safe are doing it better than anyone before them. Yes there are dams that are deficient but the industry is working extremely hard to make the good ones robust and tear out the ones that don’t provide benefits that outweigh the costs. Also 1” of overtopping is extremely unlikely to result in failure of a concrete dam. In fact one of the worst “dam disasters” involved 100s of feet of water splashing over a concrete dam in Italy known as Vajont dam. The side of a mountain basically slid down into the lake and launched water way over the top of the dam. It killed many people downstream but after the flooding stopped, the dam actually never failed. Yes many people have been displaced by dams. The cheapest real estate is always in the floodplain of a river, so inevitably it’s the poor and underprivileged who are displaced. That said, the other half of the story is that the dam will now prevent those downstream from being flooded out. All dams will lower the likelihood of flooding and often make it so that people, farms, and industry can thrive downstream. Dams in the United States are rarely built anymore. All the good spots that are feasible are mostly gone. New ones are typically pump storage, which are basically giant storage tanks without a river. Our country relies on dams every single day and you do too. Even if you don’t realize it or see it. The industry is growing fast as there is much work to do but it’s no coincidence that industrialized nations build dams, they are valuable and they are worth keeping usually. The author would be wise to consult with industry and actually understand the issues before speaking so confidently against them. I strongly encourage any viewer to research ASDSO or USSD and read for themselves and come to their own conclusion.

[@cinnac0n]

Worked in the industry too. Agree on all these points. It's important to be aware of the hazards - if the public is informed it may lead to better funding for the issue. But it needs to be considered in the context of benefits.

They have been working on Kariba dam for a few years already and still have some years left. The work needed is immense and there will be on going work after it is finished. If Kariba dam collapses it will be an unpresidented disaster. A tsunami-like wall of water would rip through the Zambezi valley, reaching the Mozambique border within eight hours. The torrent would overwhelm Mozambique's Cahora Bassa Dam and knock out 40% of southern Africa's hydroelectric capacity. It is estimated there would be consequences for Astralia and islands in between.

[@the48thronin97]

For a short period of time I lived in an apartment adjacent to a river. When I moved in, the dock and stuff was way out of the water, so I assumed it was just low due to it being the summer. I asked around and as it turns out the dam holding the river back failed. It was built quite some time ago, and while it was small enough that it wasn't disastrous, it does make a great example of our aging infrastructure.

[@benjaminmatheny6683]

Like most infrastructure, Dams effectiveness is dependent are where they are built. During the Dam boom, they looked at earlier dams to get an idea of their effectiveness. However, those early dams had been built in the best spots people could find, and the spots that remained were of lesser quality and hence made for less effective dams. The rush to build kept people from doing deep investigations, only doing surface level comparisons.

And suddenly, everyone had to get out of their homes and shelter together as the floods rose.

[@bcwbcw3741]

Dam removal is often cheaper than repairing a dam but runs into the issue off all the people who have built around the lake behind the dam and from operators who want to extract that last bit of irrigation or power "for free" since they expect to be gone before the cost of repair or failure happens.

[@matthewhook3375]

Those issues pale into insignificance compared to the issues faced by those living downstream, in the dam's shadow, when it eventually collapses. If upstream residents or commercial operators start whining about decommissioning a dam at the end of its life they should be politely told to eff off.

[@BuddyTobyTV]

Significant hazard means that if it failed it could cause loss of life. It has no basis on the condition of the dam itself. It’s strictly a measure of how high it is, how much water is in there, and what happens in terms of flooding if it were to all wash downstream on a sunny day or also during the largest storm that could theoretically happen.

[@jsaysyay]

@@BuddyTobyTV oh yeah, oops, i forgot to add that its rating is “poor”, somehow forgot that part

[@cinnac0n]

​@BuddyTobyTV The typical definition for significant hazard does not include likely loss of life, instead that would be a high hazard dam. Significant hazard is primarily related to economic and environmental damage as well as damage to infrastructure.

In reality, they function more like a baseline energy source similar to nuclear than like a natural gas peaking power plant.

The state of michigan were the ones whom really fucked up, they had been forbidding the owners from draining the lake to make repairs, while investors would not invest in the dam until the permission for repairs was secured. The property owners around the lake kept suing to force the dam owners to keep water levels at a given level, with them winning each time. This meant that the dam owners were damned if they didn't, and damned if they did, because they couldn't drain for total repairs, or lower things for piecemeal repairs.

Fortunately, as far as I remember nobody died in the process, but millions in collective property damage occurred and more importantly to us a significant loss of childhood memories and family heirlooms were lost as the basement was washed out. It took years for the replacement to be built because the state refused to fund it even though it was causing significant damage to the environment around it. Even now The replacement has drastically changed the shoreline and the quality of aquatic life due to the years the river spent drained.

I live above a dam where our creek feeds into the backend of a big lake. I’m about 5 miles from the overlook. Every time we get heavy rains, I always worry about all the people living below the dam … Where I’m at, we’re usually pretty good because the dam can relieve a lot of our flood waters here with controlled releases, but the people below it really got the shit end of the stick with location. In the fall and winter months when the lake is drained, with enough rain, it can and will fill up quick from all the runoff coming down the mountains and little holler creeks feeding into the main creek. It can cause the areas above the dam to back up quick, the flooding will start to spill out in various directions along creeks, and all that water backing up in the dam can put a lot of pressure onto it if they don’t release some it. The people below the damn are already receiving large amounts of rainfall like we are above it, so their creeks are already high, too. Those controlled releases can make their waters rise even more and cause a catastrophe if they’re not cautious… But without them doing that, we’d flood off quick above the dam from all the creeks backing up into the into the lake and causing a lot of pressure, which could potentially become a disaster on those living below the dam, as well, if it’s not taken care of ASAP during floods. It’s one of those “this way is shit, and this way is also shit but with a bit less runny messes” types of things. It’s actually pretty cool to see how they deal with it and watching all the flood waters come out when those moments arise as it’s just roaring out in large quantities, but man, do I feel for anyone living below it. The constant thought about whether or not you’ll flood off during heavy rainfall if the controlled releases aren’t done right on top of a potential burst is enough to keep me up at night if I lived below one. In fact, it’s something many in the town think is bound to happen someday soon. It’s always “only a matter of time before those repairs just can’t be repaired anymore…” and that’s scary. The amount of water that will burst out through that dam and wash away so many … ugh. See: the Buffalo Creek disaster here in WV back in ‘72. Despite it being half a century ago, it is still fresh in peoples’ minds here in the southern portion of the state solely because of how close to home it hit for many with the amount of damage it caused along with someone knowing someone that lost a loved one. Truly terrifying images and videos that came from it, and some of the stories I’ve heard from people that experienced it firsthand can help fuel nightmares. Just a big wall of black sludgy water coming right at them. Godspeed to those that live below one.

I lived (and my parents still own the house) in the first property south of Edenville dam, immediately south of the west spillway. My parents and I were evacuated the night before at around midnight, but came back the following afternoon to grab some stuff for an extended stay away from home because we were told it was unlikely the dam would collapse at that point due to overtopping. I was there at the house, only about 300 yards from the western spill way when it failed. We were the last ones across the bridge to the south of the dam before it was washed out. Our house was one of the few that did not sustain damage because we were on the west side and it collapsed on the east side and just high enough to evade the rising waters. But the house was not accessible--except by 4 wheeling through the dried up tobacco river bed--for the next six months after the collapse. We were incredibly lucky as most people in Edenville and Sanford lost their homes, or at least got major damage. Of course, this was also in the middle of COVID so we were shortly exposed through a family member we evacuated to stay with and had to quarantine for 2 weeks. Miserable times. So thanks for raising awareness about this issue, when these things fail it is very destructive. We were extremely lucky nobody died.
