Post-Spawn River Walleye Tactics
Everyone knows walleyes go into a funk after spawning, but that doesn’t mean you can’t catch fish. Expert Gary Roach tells it like it is.

Gary Roach hits the river prepared for any scenario at this time of year.
“It doesn’t matter what part of the country you’re in, those river walleyes tend to hole up and get tight-lipped after they spawn. You would, too, if you had just swum for miles up a river and then laid a few thousand eggs. Fortunately, however, those big females don’t spawn all at once, so there’s always some good walleye fishing somewhere on the river for big fish. You just have to know where to find it”.
Definatley a few view points on what those big females do after dropping spawn. I think we can all agree that whether they are being tight lipped or scattering eating anything they can get their mouths on these fish no doubt can be tough to target in any numbers. If what Ben is referring to is indeed what is taking place then it will make sense to cover large spans of water quickly and efficiently to tag up on some of those bigger fish. Here on Rainy the perch are in abundance around spawning grounds, but the big females tend to not be caught in any numbers. Seems 99% of the anglers fishing during this period have a tough time leaving a male dominant concentration of fish during that period, but that may be what is necessary to hook up with some big girls!!
This is a really interesting topic. There are hundreds of articles written on this.
