This video shows significant flooding in and around the Manawa Dam in Waupaca County. A Flash Flood Warning for the failure of the Manawa Dam remains in effect until 9:30 p.m.
Thirty-six years of dam engineering experience here. I'm smart enough not to claim I know what's going on here without a lot more information, but will suggest an explanation: Some dams are built with a concrete gravity dam where it can sit on good bedrock at the maximum height, with embankment "wing dams" to fill in the space between the concrete dam and the river banks. If done well, this is okay. What MAY have happened both here and at the one near Blue Earth MN is a flood that exceeded the design capacity of the spillway from the extreme rains, causing water to flow over and erode the wing dam. Lacking design drawings, geology, performance monitoring data, and eye-witness accounts, I include the word "MAY" in all caps.
"The City of Manawa Dam is on the Little Wolf River in Waupaca County, Wisconsin and is used for hydroelectric power and recreation purposes. Construction was completed in 1920."
Hopefully they are opening everything as wide as they can. Any water they can divert from undermining the left end will improve their chances of saving the dam from catastrophic collapse.
Yeah boy I'm afraid they're too late with this. Damn if they can stop the water. It looks like it already breached the side and everything's too bad they got almost 100,000 dams in this world worldwide in the United States. I looked online one time they got almost $60,000 boy that going to have to start checking these things. That's a lot to check out there. I wish him good luck with this one.
It's in Wisconsin. BTW

Another dam breach in the U.S.
Waiting on Blancolirio to do a breakdown.
Idky they think the dam is going to give? Looks like it made another path, like the one in MN. That should relieve pressure
Another sign of failed infrastructure 😂
All dams will eventually fail

you cant wait till last minute to act take precautions in down years a What if seek to improve ahead of time not after.

That's not supposed to happen!
what going on with all these dams failing or breaking?
Another Dam Failure.
This was allowed to happen. The gates are still closed. They were not opened up.
According to the “Official Report “. The dam didn’t fail, it eroded on the north side. 😂😂😂
Nature finds a way…
What's the green at
Mother Nature taking back her rivers...Love it...This is a good thing.
Build back better
