Do you really want to bottom bounce for walleyes? I ask this because some of the best fishing is between 10a.m. and 2p.m. in 90+degree heat! I assume the answer is YES. Here is your 1st and most important tip---PINK!!! It is the color blade that always works here.
#3 or #4 colorado or willow blade, add a few white or pink beads with 1 black in the middle and 2 #2 hooks, red on top silver or bronze on bottom about 2 inches apart with 3 foot leader made of 20lb vanish transission, then bounce using a 2 ounce bottom bouncer and move between 1 mph and 1.3mph adjusting the speed. Sometimes they want it slow and sometimes a little faster. Fish with 2 rods and on the outside alternate between copper and silver blades on the deeper side of the boat. Larger walleye like the shad look on the deeper side but keep the pink on your primary depth. Start early in the day on the rocky points and around 9a.m. search for clay banks next to points after they color up a bit, that is when the baitfish move into the colored water for cover, however the walleye can see them and ambush much easier here. Fish until at least 2 p.m. The deeper they are (thermocline) the less the sun bothers them. Also soon they will be going to the flats...real soon!
Now you are ready....GOOD LUCK!!!
