Hi Young gun,
I have fished Cochnewagon many many times over the years. I have caught a few browns out of there, but the fishing is generally slow for browns. Out in the 30 foot hole in the middle the pond, you can catch some REAL big white perch. I usually set a couple of traps down for perch and three for browns. I catch most of my browns right near the bottom in that deep hole. Maybe I'll see you out there sometime this winter.
