Planning a flyfishing trip to this area second week in June! Any experience or suggestions?

Perfect timing for top water action. I would suggest you have a good supply of poppers or other deer hair frog imitations. My biggest smallmouth Bass is during this time. It’s usually right after they leave their beds and are hungry for action. Maybe try some streamers and minnow imitations too. Find a rocky point and fish there. Saganaga is a great lake for walleyes too.
