Not all beavers damn up water, I think.

I want to say there's a type of beaver called a "Bank Beaver." They do cut down trees, but don't make log-jam type damns. Perhaps they don't make damns at my pond as the pond is already filled.

Mostly come out at night at my pond.

Excerpt from Robert Crais' "The Monkey's Raincoat:"
"She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
