Looking for any tips or suggestions about bank fishing this time of year @ white river inside white river state park nearby the Indy zoo I have been looking to get into some flatties I have been using live bait such as shiner minnows and medium to large size gold fish setup is a three oz no roll sinker set up as a Carolina rig. I tend to do pretty well in the summer months July August there catching smallies crappie channels this year I want to find a big flattie TIA.. Also if anyone knows where I can check depth chart of white river I would greatly appreciate it.
