The intention isn’t to build any dam, YoursTrue. They are building protective shelters/homes for themselves.
Yes, the structure may seemed to be like a “dam”, but the purpose is that build up of water would serve to provide beavers some levels of safety/security against predators. They would enter their “lodge” through underwater entrance.
They would also store food inside their home, such as leaves, flowers, roots, grasses, weeds, and even barks.
cladking’s idea that the dams serve as “fish farms” only demonstrated his ignorance, not realizing that beavers don’t eat fishes. The very idea that were farming fishes, is ludicrous claim.
I have noticed that
@cladking have never admitted his errors, when
@Dan From Smithville have corrected him a number of times.
