If you have a boat, I would anchor up and use large spinners. I catch lots of Salmon with this method. The use of bait and or scent is crucial when the water is dirty.
If you are bound to shore, fishing a set line approach(bar fishing some call it) is really the best method to have success other than bottom bouncing.
Again I use large Spinners instead of spin n glos and my success has gone up considerably using these.

You can read a good book, hunt for agates (a semi precious gem found along gravel bars), have a good nap, tie up some flies or jigs, build some spinners, or bring along the pellet gun and target practice.
Bar Fishing along the Fraser bars has never been about filling the freezer, but has always been a social fishery shared amongst friends and neighbors.
With all kinds of Salmon coming to the smaller rivers of the Valley soon, the chance to actively cast for fish will be plenty, so a little relaxed plunking is not a bad idea while the hot weather is here.
Good luck out there.
