Evening Fishing...where?

[walleyemaster]

I'm coming in Saturday night around 8PM to fish the evening and all day Sunday. Launching out of Saginaw River DNR launch site (Bay City). Where should I fish that evening? I want to get my limit before midnight so I can get off the water and clean/ice them down before heading back out Sunday morning for another limit.

Do BB and harnesses work well at night? If so is purple and pink still good colors at night or should I go with glow-in-the dark or chartruese harnesses? Should I fish shallow (< 10') or deeper water? Or should I put on crankbaits and troll in the shallows? Callahan reef is nice and shallow, plus close to Sag Riv launch site. Would that be a good starting point? Or should I just head out to sparkplug and give it a go around there?
