Beaver kitchen

Some time ago I tried to find beaver traces in the rivulets that flow towards our village, but I couldn't. Today, with the water level much lower, I found many traces.
This leftover of what used to be a bunch of trees in a small pond adjacent to the rivulet "Rodauer Bach" is one of them. It looks like a dining table, so many trees had recently been chopped down.
The dams, I counted at least three, were all in good shape, ensuring the water level was high enough for the beavers to hide.
I'm wondering when I will see my first one.
