Past experience is the crappies go deep in schools in the day then come in to shallows at dusk. Blue Gills on this lake flock to structure. So if you find structure, you find the gills. That’s why the cribs that were added 12 years ago generally will have shacks all over them, then get overfished. There is other good structure outside of the cribs. Having a camera helps. Perch are all over.
Just my opinion
