Does juniper beach have good shore fly fishing near camp ground?

I wanna go fly fishing near Juniper Beach PP. I know it’s salmon season then sometimes the salmon can scare the trout out of the river unless they’re feeding on the roe. Is there a good amount fly fishing from Shore if I start at the Juniper Beach campground for trout and hike away from there or should I take the extra drive and go up to Spence’s Bridge?
