I was in that area last August, we rented a cottage on Sunset Lake near Iron River. We didn't fish the lakes you mentioned but we did fish Ottowa Lake which is south west of Iron River and had a blast. It's a 500+ acre lake that is clear and deep and loaded with BIG smallmouth. It's catch and release only on bass due to a rusty crayfish problem but we also caught a nice mess of decent perch. No houses or cottages on the lake, just a few buildings belonging to the state park.
