There are a lot of opportunities for steelhead in the Olympia area. Are there a lot of publicly known fisheries, no. The cold hard facts about the south sound are that the fish are endangered. All the rivers that drain into the Chehalis will have fish, how many will depend on the river. I think you cannot go wrong with the Satsop or the Wynoochee as they will offer a lot of walk-in access. The problem with the Cowlitz is that if you do not have a boat, you are pretty much sequestered to a few very and I do mean very crowded spots. The beautiful thing about Olympia is that is is central to just about all steelhead fishing in the wet side. You can drive 2 hours and fish for steelhead 365 days a year.
