If you don't mark fish within 30- 40 min., move. Eventually you will find them. Try aggressive and passive presentations to find out what they want. Deadsitcking a jigging rap will usually put a few fish on ice. When I was there Feb.7, they wanted a shiner on each hook on the treble. 1 or 2 got fewer bites than loading the treble. Good luck and don,t be afraid to use big baits.
