This video documents a Beaver Dam collapse and rebuild on our property in Northern Minnesota. This is an update video depicting the beavers progress 1 1/2 years after a total dam collapse. The dam was an engineering marvel as it was a double decked holding back over 9 ft of water. The collapse was spontaneous and a total shock to us. We just happened to be there when it gave way. The collapse was caused by heavy rains the week earlier and not human intervention.
