Being fairly new to this forum I wasn't t sure I wanted to be bashed by the participants online, BUT eyes are creatures of habit, and there is no question that the eye,s are spawning but, how much protection is there for the young of the year to survive knowing the amount of predators that are in this small body of water with little food source. Key question is when will the spawning areas for walleye and if, will get a little protection without, suckers, burbot (ling) pike,walleye, picking off the small of the year . If they have a spawning area that is what they are looking for they will spawn when the urge hits, they have too. If this an unprotected area for the fry then the feed is on
Their habit is to spawn in the same areas as they were reared, year after year. If no flowing water is available these fish will make do, predators or not. If the natural spawning areas in PCR pick up some cover for these newby's then things will change considerably. Other than that leave this place alone and let it become what it may.
P.S. Not that old but been around long time!
