That is some nice lakers!
for trolling shiners I like to use a sliding rig like in this video: small hook in front that slides hooked through the nose, with a small treble in back on the main line hooked into the tail.
Bait, There are some guys that say if you cant see the bottom then you are too deep for salmon this time of year... I never really took that advice but it might help... This early I am all about live bait...
try dropping down to 4lb flouro carbon... It takes a while to figure them out. Single hook through snout... Are you running any cowbell rigs? I like the smaller size blades on them size 4-6 less drag. Time to break out the planer boards... I caught all of last years on them. I would be in 40ft and have the planers out over the shallows, double threat for lakers and salmon. FYI ive caught lakers in 5ft of water this time of year. Lakers I set the riggers to 10ft off bottom with a cowbell rig and sewn shiner. LOTS of work if you are by yourself... You try dodgers and streamers? 6in of 15lb flouro and dodger...
Why the other side Will? Gate 8 is nice. I'm sure eventually you will find them or break the seal and get a nice king from O.
