Crappie guy, I think what you are seeing is normal when there is a strong population of LMB and BG. Especially when BCP are introduced subsequently. The growth of your BCP is very good but the numbers are low.

BCP will do better without BG. If you could start over, it would be advantageous. If not you could try adding mid sized BCP on a ladder annually on a ladder. I think your recruitment is limited ... Mostly due to BG and a low starting population of BCP.

Crappie are attracted to light at night in the summer and fall. So from the dam this approach may help to concentrate them. They like brush too.
