Geesh! And to think I've actually kicked several out of my yard, back into the lake, when I lived in Shelton WA, on the other side of the mountain.
Mama Bear has even chased 'em off our back deck, back down into the lake with a broom....they cut-down all her little Cherry Trees, just left a "nubbin" so she was after 'em all the time.
I've seen a lot of Beavers, and likely seen a lot of the same one, but I have never seen one that was aggressive.
For the most part they were rather timid, or shy, and just hurried off out of the way.
I have always respected them, had something in my hand, or kicked them with a boot, but I never dreamed of something like this.
Betcha I have lot more respect for those fellas after reading this!
