Pond Boss Forums FISH & FISHING Sunfish-Including Largemouth and Smallmouth Bass Crappie in small pond

As long as you only have one crappie, I don't see a problem. I think the crappie will target the Gams more than the BG. One fish won't make much of a meal tho.....

If you do some searching on the forum, you'll see that the minimum pond size for crappis is much larger than 1 ac. That's due to their boom or bust spawning cycles, and the time of year that they spawn.
