The first dam failure shown is an earthen embankment dam in Edenville Michigan, it is about the same size,  construction, and age of the most typical Erie Canal Embankment

And the final report on the 2021 Edenville Dam Failure was summed up in one word... Liquefaction.

That would be when an earthen water impounding structure becomes so oversaturated it turns almost instantly from a solid to a free flowing liquid.

This phenomenon is normally caused and coinincides with a major weather event that oversaturates the earthen embankment, or when an earthen dam was constructed using sandy soils, or built without the proper, recommended soil compaction during construction.

Like old earthen dam building methods of the early 20th century, used in both Edenville and the Erie Canal.
