I have caught 3 walleye out of cranberry between there and vermilion. i have marked lots of fish in about 25 fow. caught two on a purple and gold colorado blade crwler harness. one an eriedescent reef runner. I hear that crawler harness are supposed to be the best right now. If you go east out of vermilion maybe try a little deeper. It seems like the fish just won't bite yet.
I wish you the best of luck.
