Trolling

I fish the U.P. quite a bit in the summer, but last year I saw a few people motor trolling on some of the lakes. I am probably just blind, but couldn't find any direct mention in the regs. Is trolling allowed on all lakes? I know there is always confusion on the border lakes, but I don't fish those anyhow. Originally being from WI I am used to only some lakes open for trolling. Any help would be great.

Unlike Wisconsin you are allowed to troll on most lakes I personally don't know of any that are prohibited if you do go fishing some where just check the regs for those lakes to be 100% sure

As far as I know trolling is allowed on any of the lakes. Never heard otherwise.
