I share your frustration Jhall, fished for 6 hours today at Joe Pool and caught two small ones. I've been sticking to the deeper waters so I'll have to give Steez's advice a try. How deep is most of the cover that your flipping? Are you mainly just sticking to jigs?
6inches to two feet max. I have been flipping Biffle bugs at tree stumps and washed out beach. Literally inches deep. The surface temp has been 83-85 degrees. Perfect for bass.
Don't let the "gotta fish deep in July" dudes fool ya. The lakes are fishing shallow shallow shallow right now. Record rains and coolish temps have the bass VERY shallow.
