Right on with the mouth of the tribs. There was some talk recently at my local stream meeting about dam removal on the Chiques Creek and how Walleye were found to be "stacked up" at the dam in hopes of heading upstream to spawn.
If I were heading out, I'd probably start off where the tribs enter. Not sure what the exact leader setup would be, but I know they have some chompers so you'll probably want to consider some type of bite tippet. In doing some internet reading, it seems as though any type of baitfish pattern works well (Clouser, bunny leach, etc.).
Good luck!
