I have lots of crayfish in my forage pond.
it just so happens I have been out the last few nights with flash light checking things out. I have also snorkled in the pond to evaluate whats going on.
What I have seen of the behavior is the smaller ones are in very shallow gravel and the larger ones are in the deeper water.
The gravel along the shore has lots of tiny ones the pallet towers I made out deeper are full of larger ones.
I would say run your structure right from the shoreline out to 6-8 feet deep or so and you will have cover for the size classes.
I also snorkle a lot in a the natural lakes in Wisconsin that have lots of cray fish. I see this same patern, tiny ones up very shallow and the big daddy ones out in deeper cover.
Litteraly, as I turn over logs and rocks from shallow to deep they get bigger as I go.
