I just started trapping beavers under the ice two weeks ago. I caught a 54# and a 15#, so I think my methods are right. The question I have is on the subject of the beaver itself. I'm finding areas to trap from some maps I got from WS from their beaver fly overs. Every weekend when I go to check my sets, I try to find another area to set. The areas I have set I know have beavers since I caught one at each spot.The lodges have freshly cut sticks on them and obvious feed beds. Other areas I have scouted I found lodges without fresh cut sticks on them, do they use lodges from year to year, and if so shoud I not worry about the lack of fresh cut sticks on the lodges? Another Question if the beavers are gone how long do their dams last without them there to tend them?
