I don't fish Arcadia lake, but I do fish Hefner regularly..

I went yesterday at the dam along the rocks, my dad reel in 4 big crappie.

They was full of eggs, seems it is still early, I give it another week or 2. I know they are in there, but they do not want to bite much. They move in much closer to the shoreline and they are waiting for the right time or temperature to start.
