If you want to try and catch bonus coho or herring while targeting lake trout here is my suggestion on what to do based off what I experienced. Drill 2 holes next to one another or 4 if you have two guys. Have one rod rigged up with a smaller spoon style bait about 20 to 30 feet down that is more or less a dead stick in case a school comes through while you are jigging deeper for lake trout with your larger presentation.
We had a number of times through out the day when we would have a school come through at around this depth no matter the depth of water we were fishing in. We tried to reel up with our larger trout baits but didn’t have much luck hooking these fish because I am guessing the bait was too big. They came and went so fast that you didn’t have time to drop another line down and try and catch them.
We never did catch a lake trout, but if we would have our plan was for the other guy to reel up the other lines quickly so that nothing hopefully got tangled.
My buddy also got a trout stamp for last weekend, but when he looked closer at his license when he got home it was for 2019…
