St. Mary's Atlantics
In my limited experience, most of the Atlantics in this river system are small, about the size of grilse in ocean going fish. There are fish over ten pounds and there may, indeed, be fish over twenty, but most of what I've seen would be six to ten pounds if accurately weighed. Because of the strong current throughout the rapids, these fish will put a bend in your 11 weight. And of course, the strong rod would be almost a necessity to land a large fish due to how difficult it is to wade after the fish with any speed. Are you fishing with Karl Vogel as your guide? He kept me from from swimming all the way to Lake Huron several times! I now wear SOSpenders whenever wading there.
