There is a run of sockeye that returns to a little spring fed swamp backed up by the road near it's end in the park - can't remember the name of the creek but it has a little rock fishway on it and I've seen several adult sockeye in it in the fall.
Sometimes you expect to catch a fish so much that you catch one anyway, even though there is no way you should. Like the time I was in high school, had just built my first steelhead flyrod and took it out the first of June to the upper Kalama, which had just that year been designated fly fishing only water (yep, I'm that old

). In the first pool early in the morning I promptly hooked and landed a summer steelhead - the first one I actually landed on purpose. Fished the rest of the morning then went down to the #2 hatchery for some info. The told me not to bother to fish above the hatchery, where I had just come from, as they only had passed one summer run steelhead over the wier so far that year!
Another time ages ago, 1974 actually, when the Quinault was open year round and bull trout were known as dolly varden and were pests to be eliminated, I was fishing in early April for them with another new rod I had built, this one a 3 weight flyrod made of graphite, the first rod I had made from this at the time new, space age, and expensive material. I was loading up on dollies at the mouth of Alder Creek - they hit a skunk fly with gusto as it looked just like the dark little sockeye fry that were migrating from the clear stream into the glacially turbid Quinault, when a monster steelhead floated up and inhaled my fly. With this new, light, and expensive rod that I was afraid to put any pressure on I was sure that fish was a goner when it roared off into the river jumping all the way, but after running all my line and most of my backing off it decided to swim back up into the creek. It repeated this about 10 times and finally wore itself out and I was able to beach it. This turned out to be no old boot of a winter run but was instead a chrome bright 10 pound summer run, nearly too immature for me to tell what sex it was. That sold me on graphite - I not only didn't blow the rod up but I still have that little jewel today.
