It would be a Blacknose / Black stripe crappie, the Magnolias are used to stock ponds and aren't supposed to reproduce, the blacknose is a natural occurring variation in black crappie, pretty rare. And on a side note, Enid is the only lake of the big 4 family that has had a need for any kind of restocking of crappie, and no Magnolias were introduced I'm guessing. All the other 3 lakes have the native crappie that were in the rivers prior to the damming of them, none were introduced. I still call blacknose crappies Magnolias too, even though technically not correct it just sounds better. Either way cool fish, I've only ever caught one as well, and coincidentally it was on Sardis.
