Funny that beaver dams never break. You would think that since they're made out of untreated wood, that the water would rot them at some random point that beavers can't even foresee....
I don't know if you were joking, but beaver dams break all the time. Usually they're not huge breaches but little leaks, and not usually due to wood rotting but due to mud washing out and sticks coming loose. The little guys are constantly repairing and mending the dams. They have OCD and can't stand the sound of running water -- that's their trigger to fix the dam.
