What is better 5 size trap, shallow close bank or back an deep ? Never try or catch much back an deep when did

Back foot preferred always. Some slopes don't lend themselves to back foot sets though. I that case either dig out a trench or construct a set that favors back foot or choose another method such as a snare. If the front foot is the only option choose a trap that grabs as high as possible to get above the fragile wrist and always on a drowner for a quick kill.

What ever the particular terrain dictates but try for back foot if possible.

So about 18 inches back from shoreline an offset to downstream side a little with no breast sticks ? How deep minuim water depth by trap ?

Paul taught me to use #5's or CDR's and I've been very successful with them.
16-18" back
Breasting sticks are for use at dam break sets.

Breasting sticks are for traps set shallow so as get beaver to breast an walk into trap an not spring chest

When I trapped beaverw/foothold I always went with a front foot. Set close to the shore with breasting sticks out from the trap on a slider. Often in 2-3 feet of water.

I had purchased #4 Montgomery's 4 coiled and later added to the jaws some more width. The chain I replaced with two swivels and chain that looked like a small logging chain.

It never broke and added to the weight for the slide.

Setting for a front foot I got the beaver walking no need for breasting sticks.Or just lay a good sized limb In front of the trap. It just acts like a stepping stick. Make sure you anchor It so It doesn't float away.

I just never try much set back an deep for beaver, I did with 3s, years back not sprung trap an nothing, always shallow close bank , but now got new no. 5 size traps
