Hey everyone. I've been fishing crappie for a long time but it's always been in shallow lakes and bayous and never needed any brush to attract crappie. Now that I am fishing a larger and deeper lake it seems brush piles are the way to go. I just started putting out brush piles a few weeks ago in 20 to 30 ft of water using sweet gum and willow. My question is, what would be the maximum depth to put the brush piles and still be able to catch crappie, winter or summer? Thanks
