Not sure where to post this, but I figure that structure creation may be a critical factor here so I posted here.

I've heard many times that Crappie populations are cyclical, yet it seems that most Crappie hot spots remain strong year after year. I'd like to hear what you have to say.

My guess is that structure plays a key role in having areas of refuge in which to spawn which should affect populations, but are there other key factors?
