Lake Ontario isn't really setup for a huge population of smallmouth. It gets too deep too fast and lacks the offshore structure to add to their habitat. I'm not saying that there can't be a healthy population in certain locales, because the Niagara river and the bar area has always been a prime location, as I'm sure your favorite spots on the east end do or did. Just like Erie doesn't really support a healthy population of salmon because it just isn't setup for the needs of that fish.
