I saw some guys breaking down flyrods near the Agate Passage bridge the other day. I suspect that might be a spot.

You should be able to get into resident coho and searun cutthroats from the beach. Use a floating line, 11 foot leader, and streamers that look like sculpins or herring. Cuthroats will be near creek mouths. Please release them.

Coho may prefer a faster retrieve. Look for baitfish being chased - you'll see them breaking the surface.
