Beauty 'eye you nailed there, I'm guess you must have been in the east part of the lake.
I have fished Baptiste 6-7 times over the years and seen nothing but pike (tons of them), bass (LM/SM), muskie (once) and panfish. Never a Walleye, though I knew they were in there as they had been stocked in the past. I have focused more on the central/west part of the lake, and havent hit the east end of it yet.
All in all, its a gorgeous place to spend some time out on the water even when the bite isnt on! I personally love walking a suick jerkbait across the surface on a calm evening in dog bay over the sunken logs. There are always agressive pike ready to ambush!
