The best summer locations for northern pike fishing can be areas adjacent to open water rock humps. There are many areas which could work on LCO. By the end of July into August focus moves into the lake section with the deepest basin. Sonar returns dictate where to fish. Look for high broken bait fish schools as opposed to deeper tightly bunched large schools. You are likely to run into a pesky walleye or two when trolling, even when using large musky sized deep divers.
I haven't trolled lately, but I would expect the best of this bite to end soon if it hasn't already. With cooling water temperatures the pike will return to weed areas.
