Can browns be caught in lakes?

[wiperhunter2]

We tried trolling right in front of the ramp before we left because there was few boats there but no luck, I thought maybe the PWC ramp might have been where they dumped them, if not at the other ramp. We tried all sorts of lures, even spinners and spoons. That Spring time/ ice out trolling time, might be a good time to give it another try. We tried between the buoys and the river, that was where we marked the most fish but no luck. Black and orange flies or buggers, wonder why that pattern got their attention, maybe perch[:/], there are no insects of that color are here[:/]?
Nice spots on that one brown.
