If you have a depth finder on your two-man, I would try to locate brush on those drops, (the areas where the contour lines are close together) this is where the big females will be staging. Either mark it with a buoy and anchor 20-25 feet away and cast a slip bobber set-up and a minnow and just let it sit. Or, rig up a couple of jig poles with your favorite jigs and slowly troll over the brush. From the bank, cast a minnow about 18" under a bobber and let it sit. You can also cast a jig/bobber combo and slowly retrieve it back to you, giving it a little pop every now and then. Set the hook at the slightest twitch. I hope this helps, good luck!
