On a walk at the end of August 2010 we encountered a pair of beavers trying to make a home in our local lake. They were very busy, presumably because they have to get sorted before the cold weather comes. The plan seems to be to dam the outlet to our lake, let the level rise, then pick a spot in deep water to make their home for the winter.
We took a remarkable video of one of the pair bringing in a tree branch and planting it in the culvert. It is on You Tube, and hard luck on anyone searching for 'beaver' - this is the other sort! Go to http://www.youtube.com/watch?v=IW3AAhg8jNM.
They never stopped all the time we were there. The local trail warden was concerned as they are damaging the woodland and if they succeed in flooding the lake, there could be damage to local houses. They have managed to fell a couple of trees, with 10" trunks. We think this is in the hope that the trees will float down to the outlet and help with their damming activities.
The warden is trying to get the authorities to move them to a site where they can do their stuff without threatening the local infrastructure.
Evenings are getting considerably darker now, and the sun is going down at 8.30. Very little time for the beavers to settle into their winter quarters so I hope the Alaska Dept of Wildlife comes to their rescue.
