What was wrong with the Banqiao dam?
Typhoon Nina–Banqiao dam failure, catastrophic dam failure in August 1975 in western Henan province, China, caused by a typhoon (tropical cyclone). The ensuing floods caused more than 150,000 casualties, making it one of the deadliest typhoon disasters in history.
Did the Sanford Dam Break?
The Sanford Dam was built to provide water level control for the purpose of hydro-electric power generation and received its original license from FERC in 1987. On May 19, 2020, the Sanford Dam was overtopped by increased flow from the upstream Edenville Dam breach. This led to the Sanford Dam failure.
What happens if a dam breaks?
Flooding can occur if a dam fails. Alternatively, a dam operator may release excess water downstream to relieve pressure from the dam. That action could cause flooding, too.
How did Edenville Dam fail?
The Edenville Dam was situated at the confluence of the Tobacco and Tittabawassee rivers, while the Sanford Dam was downstream on the Tittabawassee River. After two days of heavy rains, the Edenville Dam failed around 5:30 p.m. on May 19, 2020, unleashing the reservoir behind it.

What dam failed in Michigan?
An independent investigation into last year’s Edenville Dam failure in Midland, Michigan, found that as the reservoir filled to a record high, the dam’s loose-sand embankment became waterlogged, causing it to liquify and collapse under the pressure of the water backed up behind it.
What would happen if Hoover Dam was destroyed?
Damage to the Dam If catastrophe struck the Hoover Dam and it somehow broke, a catastrophic amount of water from Lake Mead would be released. That water would likely cover an area of 10 million acres (4 million hectares) 1 foot (30 centimeters) deep.
