I don’t recall seeing any vids specifically geared towards high water,,,but I can comment on my experience over the last two years.
I am having decent success for walleyes by fishing exactly the same way I did in normal flows…the difference is just the spots I fish. Last week a buddy and I caught big fish on a wingdam that I’ve never even seen anyone else fish, much less fished myself. Actually I didn’t even know it existed because during normal flows it was shallow and silted over.
Get scouting and good luck!
