A few sockeye are found in virtually all the region's anadromous rivers. Those fish typically are different that those found in various lake populations (Lake Washington, Baker, etc.). They typically are earlier spawners (August/September) and are not using lakes as part of the life history strategy. Though it is pretty common to find them spawning in the exact same location from year to year.

One interesting twist is that the various river populations seem to share a common genetic background that is different from the various lake populations. One theory is that these river "populations" are the colonizing fish for the species. These fish are constantly probing river habitats and if they stumble upon new or vacant habitats (large lake systems) for the more a traditional population they take advantage of that habitat and through the natural selection process they quite evolve into an unique lake dwelling population.

They occasionally show up in surprising numbers in unexpected locals. One such case was upper Deer Creek on the North Fork Stillaguamish where several hundred were observed one year in the 1984 and a handful in 1985. To my knowledge sockeye had been seen in the basin for decades prior to or after those min-1980s observation.

BTW -
It probably is good to remember that these various anadromous salmonids have been quite successful for eons using these type of strategies that may not make much sense in the short term but are essential for long term survival. Don't forget that just 12,000 most of our river valleys were under a mile or more of ice.

I just today tried to explain this concept to my wife and sister after we briefly watched a show about king salmon. I love that fish figure out how to find new habitat. I wish I would have thought of the Ice Age example.

The hike into the upper Chillawack Valley is a spectacular trip giving the hiker a snap shot of what the low land forest must of once been like in this region. You will find the classic example of old growth forest with huge cedars (diameters of 10 to 12 feet).

While seeing the various fish species (including sockeye and kokanee) is interesting the real eye opener is how wonderful that undistributed river habitat is. Once viewing that habitat it is easy to see why fish production levels have been so significantly reduced in nearly all of our streams.

You could hike to Hannegan Pass and camp, hike down the Chilliwack the next day. There are some spectacular views from the pass. The last time I was there we did see bears so hang your food.

I caught one just below Fortson in the early 90's
