Oncy, I'd have to go back and look at some of the spawner survey and trap data buy, yeah, late August doesn't seem out of the realm of possibility for summers, especially if the spawn in a larger stream. Summer chum, at least those I worked with, were small and I found some in a very tiny creek in Sequim Bay. Although most chum stocks are 3-4-5 the summers (at least some) are 2-3-4 and maybe 5. The streams weren't large enough in September for a 20 pound 5.
