I have checked and double-checked and must tell you that dams are not, in fact, airplanes.

Ninety-one-THOUSAND? Damn, that’s a lot of dams! 😳🤯😮

Thank you for drawing attention to this looming issue.

I work at 3 dams that are 100+ yrs old. This year we've spent $400,000 on maintenance. We just had our federal inspection and passed.

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.

As a child in the 30s, my mother lived in a workers cottage on a floodplain. Twice a year they moved the furniture upstairs, watched the water wash in. Then cleaned the mud out and got on with life. In their retirement, my parents lived in a house half way up a mountain, 1000ft above the nearest river. Her priorities were absolute. I learned a lot from my mum

I'm from Zambia and you did a good job talking about the Kariba. In our history class, this relocation is painting in a really positive light, it's just later on in life that I found out it was pretty much compulsory... it was more a command and not an option.

If you want to learn more about dam failure I highly recommend Pratical Engineering. he's got a bunch of videos on dams, and dams / critical infrastructure failure. The culprits are too often the same: maintenance budget cuts and inaction.

Tragic what happened to Libya in the weeks before, almost 30,000 people died from floods and it's just heartbreaking

The Assuan dam at the river Nile in Egypt is also worth mentioning. Not only did it flood an enormous area with all mentioned consequences to the population and the environment, it also stopped the annual Nile floods. These floods brought fertile slit to the fields alongside the river, that had fed the people in the area for millennia. Of course they played a key role in the prosperity of ancient Egypt too.

That edenville dam was less that 2 miles away from my Uncle's house, but thankfully they were uphill and didn't get flooded. The more worrying part was that it flooded the local chemical plant, which possibly lead to contamination down river

I've personally lived in Michigan my whole life and was one of the people who had to evacuate due to the Edenville and Sanford dams flooding so to hear Sam's voice narrate this story of my hometown is surreal, great content as always!

As a dam ages, it incurs damages.

honestly, as a dutchman, any piece of critical water-management infrastructure being privately owned is absolutely insane to me. Like these companies have no incentive to care about public safety, so handing them such a responsibility seems like one of the dumbest things you could do.

Minor note on precipitation unit conversions: While centimeters are usually the more common measurement in metric, in the case of precipitation, millimeters are the standard. So 3 inches would become 76 millimeters (well, assuming it's

overwhelmingly the biggest problem is that the majority of these dams are privately owned (and have been for decades). This means private companies got to take all profits when the dams were in good health and now the government (the taxpayer) will have to step in and pay to fix all the issues private corps let happen

I was born and raised in Midland Michigan and I was in Midland during that dam burst and it was crazy. My side of the town didn't end up getting flooded but the side of town that my highschool (dow highschool) was on got completely ruined. I had multiple buddies who had parts of their houses completely destroyed. I still have video on snapchat of me going into my school after the flood and seeing my highschool pool, the library, and multiple classrooms destroyed. Crazy ass times.

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.

We also had 2 recent tragic damn incidents in the state of Minas Gerais, Brazil. Hundreds dead and thousands impacted. Mining companies seem to be finally changing their policies to do better risk mitigation

Not only people were displaced when Lake Kariba formed, but a lot of wildlife as well. Some of the animals had to be tranquilised then moved on barges or boats to higher ground as the water level rose.
