My best experience with walleye is in the Delaware River using jerk baits …. Which does not apply to lake walleyes. My best suggestion is to search YouTube, especially from the Pa or NE US area to get some ideas.
I have bought some lures to try on walleye, Rapala Jigging Rap to be specific but I have not yet taken the time to pursue them. When in doubt though, it’s hard to deny a live shiner.
Where to find them in a lake I think is the more difficult part. I “believe” I have located them in Blue Marsh in 2 spots and they are the 2 deepest parts of the lake and coincidentally, off of large rocky banks.
