Here's my best guess:
I would setup on the first major drop off on the north end of the lake.
especially if I can find Rock or gravel or other structure.
Drill holes at the base of the dropoff, and up on the flat. Fish will start hitting deep, and move shallow as the bite continues.
(make sure you've got all you're holes drilled, no need to spook fish drilling more holes after the bite starts)
The main lake basin won't be as good a place to start, because you have a major inlet which provides fresh oxygenated water.
I would setup close to the area(s) that will be used for spawning in spring, but be careful, the ice may be much thinner in these area(s).
The major bites will be dawn, dusk, and throughout the day. Use Jigging Raps, Salmos etc in perch and glow patterns.
Perch have poor eyesight and will disappear during the hours of darkness, which means walleye feeding will also be limited.
I would also try to find any deep water holes or troughs to fish during the day.
Use hole covers, you don't need open water to "shine" light onto an area that you are trying to fish.
Hope this helps,
