What percentage of your mink catch is on dry land? I have found over the years mine runs about 50/50 dry land to water, though I do use a lot more water sets.
I have not had good luck on bottom edge sets in my area due to the bottoms generally being sloped muck lots of bottom just few edges. I have read and heard others talk about Johnny Thrope and it seemed he liked to use high dry bank sets and I find those to be more productive on my line by percentage of traps set.
Just wondering what others find on their lines.
For me that would be completely based on when/how I was trapping. I grew up on dryland mink in the late 70's and early 80's with my dad on his fox line. He would not allow me to set anything in water so that I wasn't wet and complaining all day and had no body grippers at all, dont think we hardly owned any to speak of. plus setting dry in the brush wasnt where you trapped reds back in those days so it kept me out of his hair so he could concentrate on the high dollar critters. That means even to this day I've got a soft spot for setting banks and even spots quite a ways from water. Bet I was in my mid 20's before I ever caught a wet mink. But I havent trapped dry like that in years. Was probably 15 years ago that I spent a few seasons with a real good small stream/creek mink trapper from western part of the state that has now passed away. Because of that, if I was to run a serious mink line these days before freeze up in this state, I'd likely have about 50/50 mix of wet and dry sets. Fairly convinced at least in these parts that running just one way or the other isnt the best option as we dont have intense mink population. I've gotten away with specialization on things like coon running 100% dry land conibears and had fine luck but with a zillion coon around you seem to be able to get away with that option.
i only mess around with some mink these days when im bored. it tends to always be after freeze up. and the bottom edge tends to have its place and even shine in that weather. but i suspect your water is similar to much of mine---ditched muck/peat in a perfectly straight line with very little structure that may be a foot wide trickle in the middle of a 20 foot wide ditch one day and flooded 20 feet wide and 5 feet deep after the next rain. that terrain makes for a hassle for bottom edges as in you have to spend so much time looking for the one great spot. you may find in those ditches filling the entire thing from side to side and top to bottom with colonies gives you interesting results if the ice holds up and the flooding stays at bay.
