The collapse of a dam built by Beavers

In 2015 in northern Minnesota, a Lake emptied after the collapse of a dam built by Beavers. Rodents did seven years to build this dam, elevating 0,5 meter per year to reach over 3 meters in height.

The dam finally fell and the lake emptied in 4 hours. Only six weeks after, beavers had already begun rebuilding a new dam has already reached 2 meters high.
