Are you seeing the crappie at depth on your sonar? I think 32' may be a little too deep.

I might consider a small pipe "brushpile" in 10' of water, then move deeper on roughly the same line and build a bigger one in 15' of water, and finally move out to 20' deep water and build a bigger one. On the deepest one, build it up to within 10' of the surface, and maybe have a small section of the brushpile within 5-6' of the surface.

Once you determine which brushpile the crappie prefer, then you can build more at the optimal depth in Year 2.

Good luck on your lake. Sounds like a fantastic situation!

P.S. Can you add a rough location of your lake? Some advice is universal, but some guidance varies strongly by region.
