At considerable risk, I'll stick my nose into this discussion, perhaps to add a different perspective.
I don't fish the Skokomish River but if I recall, isn't that the river where Tacoma City Light illegally built a hydropower project on the North Fork, in the middle of the Skokomish Indian Reservation (the Cushman Hydro Project)? Isn't that the project that was built without any fish ladders? Isn't that the project that has been operating illegally (i.e. without a Federal license) for the past 75 years with no measures to protect salmon and steelhead? Isn't it Tacoma City Light that continues to thumb it's nose at the Tribe and their legitamate concerns regarding how they (Tacoma) illegally took their land for their project? Isn't it Tacoma City Light that is raking in a ton of cash from this project but the tribe continues to get nothing in return even though the project is located on Skokomish Tribal land?
This injustice occurred many years ago but the impacts to the tribe and the fish continues to this day. Why hasn't the Federal government taken any action against Tacoma for this? What affect does this situation, and it's lack of resolution, contribute to the bad feelings on the part of the Skokomish tribe?
None of these problems justifies the concerns expressed on this thread (e.g., snagging, trespassing, potential violence, overfishing, excessive netting, inconsideration behavior, etc). However, the tribal members live in the shadow of a continuing insult to their reservation, the river, and the fish. It's very unfortunate they seem to be taking out their frustrations on legitimate sport anglers. But from their view, it is our Federal government's lack of corrective action that has caused this situation. To some extent, they are not wrong.
But I will emphasize that this does NOT excuse their behavior. It only helps explain it. So, instead of pointing fingers at each other, sport anglers and tribal members should collectivily focus their anger at another source for the problems on the Skokomish River - Tacoma City Light.
