Like REEL TRUTH said, There will be Summer stealhead in the Siletz, The upper gorge is only open to the public on the weeends.
Just south of Depoot bay is Yaquina Bay. There is usually quite a few rock fish there. The south jetty is where to go. If you bring along your own boat try fishing the fingers along the south jetty at night. Its pretty safe but use lots of caution only fish here at night n an incoing tide. In the past we have kicked butt on black sea bass in there.
