You could always consult the fish and wildlife folks too. I would think they have more of a vested interest in boater safety on the river during spawning season than the sheriff's dept.
WDFW has very few officers in the field in this part of the state. Most of the fishing license and boating regulation checks are done by the state police.
Salmon fishing is very competitive and every decent fishing spot is packed to the gills as long as the fish are biting. It's especially crowded at the beginning of the salmon season. It's not very enjoyable fishing, but that's the way it is. There are more fisherman and boats than a spot can handle, and there is a a strong "weekend warrior" vibe. You know you are only going to be here for the day, nobody knows you and you're not coming back anytime soon, so there's no incentive to be civil. You are going to get yours and F everybody else. There's aholes everywhere, you can't get away from that, but when when somebody threatens another's safety, either with a gun or a boat, that is crossing the line.
