When are you planning on being there? Walleye fishing can be very good in the spring and fall but be prepared for lots of company, especially April and May. It can be a PITA at times, with boats zooming by too close, but I guess that can be the case anywhere. With that said, it is a beautiful area to fish and action can be very good, sorting thru many shorts to get a few eaters and slots. High water can be a pain; I look at streamflow charts before heading over there. If you’re flexible on location or considering another trip, take a look at Petenwell Flowage and the stretch of river that leads into it.
Don’t know anything about Holiday Shores.
