Dam busters and builders

One of the first things I did on my return to Poland was take Jackie for a walk and check out the beavers, or should I say the beaver evidence; having never seen one yet.

Beaver Avenue, as I like to think of it, has been cleared by man and chainsaw and little of the autumns industry remains; just lots of flattened stumps.

Further afield, where I first reported on the beaver activity last year, only a few sticks remain to suggest these large rodents had worked so hard last year; Man 2 Beavers 0.

But then today, taking a different approach to the most prolific tree felling area that I have come across yet, I started to see the evidence of a building project. First of all I noticed that one of the irrigation ditches had started to dry up, whilst those around seemed to have a good level of water, so following the ditch  for another five hundred meters I discovered the blockage; a well formed damn and close by, the possible remains of a lodge.

From what I have read most beaver activity goes on in the autumn in preparation for winter; the summer months are spent roving, so I’m wondering is this is a new or old structure? I had never noticed it before even though I have walked this path a few times.

As you can see the water is backing up nicely and if the dam was any higher then the surrounding fields would be water logged; clever beaver engineering or just coincidence that the height is set as it is?
