I enjoyed the lassale Bridge, But I can only limit my experience to summer time down there as well. I can say the depths are definitely in our favor. If i was fishing their tomorrow I wouldn't stray far from what I've been doing in my videos. Light line, And close to bottom fishing might be key. I usually find bottom and stay about a foot up. You can just throw jigs, of coarse live or powerbaits will give you a better shot if your not much of a Jiggn man. By that Smallie in your pro. I'll say that you are
I don't usually use any scents or Baits because I'm a mover
And once you find them, you won't need much to catch them. Waters colder there Stay close to the bottom, Work your lure's slow. That's a decent start and the fish will tell you how to adjust from there
You may pull out some Perch or trout still in the River.
Let me know if your up for a spring time River Walk slayin
