Local lakes have been heating up and will get dangerously (for the fish) hot in the next week or so. Shallow places like Leech Lake will be at 70 or over and you can kill the fish by stressing them. Deep lakes, like Chopaka, will have very warm surface temps and fighting the fish at the surface does them harm. It would be best for the fish to just stay on the shore and look at the pretty sights, or take a hike. The fish will be there waiting for you when it cools down.
