If it's easy to add to your line, set it. I have very little sign here but still catch coyotes. If not for trail cameras I would think the coyotes did not go through several areas I trap if trail cams were not telling me they are there

If you have a camera and it's a spot that it won't get stolen. Set one

A live beaver pond will hold way more furbearers.
Scout the rest of the watershed for live colonys.Those will be your fur pockets.

if you can get up to the old lodge and the runs are open into it. Why not try throwing some bait up into the runs, beaver meat or something and keep an eye on it. That sounds like a pretty good bobcat set or other canine. Just a thought.?.
