Both lakes should fire up this month. Drifting live minnows below both dams should bring plenty of rod bending from trophy smallmouth to plenty of catfish and white bass for the cooler. Drifting current seams and eddy pockets just off the main current flow will be your best options.
For crappie search out Bear and Second Creeks on lower Pickwick Lake. trolling in 15 to 20 feet of water over ledges should be good. On Wilson lake McKernian and Shoals Creek will be the hottest crappie action. Sauger should start schooling on gravel bars from Second Creek to Natchez Trace bridge. These fish are starting to make a small comeback on Pickwick.
For trophy catfish your best options are the deep water bluffs on Wilson Lake. Slow troll 70-80 feet of water from Shoals Creek to Wilson Dam for the chance at the fish of a lifetime.
