I think seldom may have been referring to what I call the silt set.This is a winter set to be used when ice is on.Its a modified pressure set.The pressure set is a common set used in open water or when ice is just coming on.
The silt set is an otter set developed by one of our council members who traps a ton of fur of all species.I named the set.
First is to locate old beaver dams that still hold back water,or a fresh dam is good if you remove the beaver first.
This set will work where the millette set wont in winter,The millette set is deadly but has to be made at a dam on a creek with a constant water flow.The milette set works better in extreme cold.
The silt set can be made on a bush runn off creek,since you dont open a large breach in the dam.
Once you locate the dam look on the downstream side for any sign of water going thru downstream.
When you locate those spots,go on the upstream side and carefully open the ice and look down into the water shading yourself so you can see.Stir up some silt and look for a little current which will clear the silt you have stirred up.If no current ,then its not the best spot for the set.If you notice current,take a long pointed pole a couple inch in diameter and ream out a hole down at the bottom to make a bit more current.You want to keep the reamed out hole small so as not to make the water go down at the upstream sideThen set the 220 out far enough so it wont freeze in the top jaws.Then fence from the trap back to the dam on both sides at a 45 degree angle to make a little pen.To keep the trap from freezing in between checks cover the pen with a good bunch of spruce branches to make an air space then bank it all up with snow to insulate.
This set works because Otters when travelling under the ice in winter are always looking for a place to get up or downstream of a dam and they feel and follow current.They also look for places to get up on top of the ice or get under the ice.This set fits the bill for all 3 scenarios when otter are travelling a bush run off creek in winter.
A lot of old dams will have two or three spots for a set,but be cognizant of the flow so as not to drop the water which will cause the traps to freeze in.The set will take otter mink and rats,and in some locations two or three traps can be set side by side at the pen to take multiple otter per check.If setting 220s side by side use block sticks so one animal when caught cannot fire another trap like when setting multiple bodygrips at the beaver main den entrance set.Also twist trigger wires together and move to the side and have trigger on bottom same as beaver den entrance set or millette set.
