Winter Trapping (over the next break)

This year I’m going to try to extend my trapping season to its fullest legal length by trying to trap over Christmas break. Usually trapping in the snow and ice is very hard and unproductive to accomplish as most of the fur doesn’t even move during these late winter months, except close to their dens. It will be crucial to locate these dens if I plan to successful in trapping over break.
I will be in the pursuit of primarily both beaver and ‘coons. I had great difficulty in trapping these two species over fall break, and now that the conditions are tougher I’m not expecting my catch rates to be too high. However, I hope to be able to bag some more game, which I don’t usually do over winter.
This winter trapping will require some unprecedented trapping tactics and methods if I plan on being successful. . I usually trap just in the water, which is frozen at this time of the year and will occasionally place some dirt hole (land sets), but this has also been “shut down” by the snow. To be able to do these things I will be pursuing the ‘coons in several old barns that I have permission to and at an old bridge where I have seen several ‘coon living this year. I’m also aware of where a couple of beaver colonies are living and I will try to target them there… under the ice.
For the ‘coons I plan on using almost all bucket sets with 160 and 220 conibears and some snares if I come across any well used coyote and ‘coons trails and crossing logs. With the beaver, I will have to trap them through the ice in order to even get to them, I plan on using my ice fishing auger to drill a hole, and then attach a 330 conibear or a #4 coil or longspring on a 6 ft pole into the hole. This is a set I’ve never done and I picked this tip up from an old trapper, and I would be ecstatic if I was actually able to be successful with this set and catch a beaver.
I will make a quick entry after Christmas break if I (or don’t) have any success with trapping.
