How do beavers coordinate construction?

Do they all just go at it and organically combine efforts or is there some kind of lead beaver that directs the others?

A surprising amount of beaver dam construction can be boiled down to the simple rule "pile sticks on the sound of running water", though there's clearly more to it than that.  Still, there was an experiment where someone left a loudspeaker playing the sound of running water out in a field near a beaver dam, and the beavers buried it in sticks.  At any rate, it's unlikely there is any top-level control.
