A couple of years ago my wife and I heard about good spot for perch right after ice out. We take our 16' beater boat up the rock strewn river near a dam. The perch stack up there during spawning. The river is a tributary to a larger river. It meets the larger river about 5 miles from where we fish open water near the dam. Would it be reasonable to think that the perch currently might be staging up now where the tributary meets the larger river? I'm not sure if the perch that stack against the dam just come from the tributary of if most of them come from the larger river and swim up the smaller river just to spawn. The "small" river is probably 300' wide on average and the larger probably 600' wide where they meet (just to give you some perspective). Provided the ice is safe where the rivers meet, the thought of doing some ice fishing at that point now has crossed my mind. I'm I thinking too much or is the logic sound?
