The beaver is an animal and engineer skilled at building dams and water barriers

The #beaver lives in streams, swamps, and ponds and builds dams from tree branches, stones, and clay. It is capable of constructing the most complex structures on river banks. Its strong teeth are its main tool for performing this arduous task, as it relies on the teeth to bite off tree branches and twigs. Beaver builds dams up to tens of meters high. For example, the Alberta Dam in Canada, which is 850 meters long, was made by beavers.
