Welcome to Pond Boss Alpha Wolf!
Give us a few more details about your lake. Do you live on the lake, what other fish are currently present, etc.
The thing about crappie is they have a tendency to overpopulate and stunt in a smaller body of water, something under 20-30 acres. They spawn early and unpredictably, are predators, and have larger mouths than BG, giving them an advantage over them. There are a few guys on the forum, however, who have managed to keep a crappie pond in balance through some very aggressive and attentive management. This is the reason I ask if you live on the lake. If so, you can possibly give your BOW the attention it needs to make a crappie population work. If it's a lake you visit only periodically, however, crappie may not be the direction you want to go.
I'm getting better at the search function, so let me see what I can dig up here...
