There was the year I was working for a startup in LA, spending a week on the west coast and the rest of the month at home in Upstate NY.
I would go swimming in a pond that was full of what I call "freshwater seaweed" and I got a permit to stock it with Triploid Grass Carp that would eat it.
The next summer I tried to go swimming there and ๐๐๐๐! I got out of the pond and saw a beaver swimming around in circles and realized he'd hit his tail to warn me away. Then I noticed that the pond was full of beaver turds and remembered that that's the way you get

so I haven't swum in that pond since.
I've had beavers living in the wet meadow on my farm for years and we always have somebody taking the dams apart so the driveway doesn't get flooded. It's not a terrible chore if you never let the water level get high near the driveway -- if you do they get a lot more productive and it's a lot more work.
