I woudldn't get my hopes up. I think there is a depleted run of reds/sockeye that still use it to spawn. There is a large pond past Dickey "River" toward the ocean that had planted Rainbows in it in the early 90's.

I pursuaded the locals we were with then to stop at the Dickey R. bridge long enough for me to wet a line on the way back to Forks. When they wanted to leave while I was fishing below they did a gigantic smoke show/burn-out on the wooden bridge. I got the message and hurried back up to find they had started a small fire on the bridge!
