It's interesting that there is such a diversity of opinions. However, I agree with cohoangler mostly. The Tuesday after all the hooraw about the Dungeness and its silvers, I visited the river on a trip I'd planned a week or so before (and before Gooose's posting).
I was late getting moving and made it to the river about 8 or so. I drove by the area Gooose had mentioned, expecting to see a flock of cars given the flack on the board. There was one truck. I passed by and headed for an area I like to fish. I saw two anglers during my morning on the river and caught a couple of nice silvers.
Since I wanted a couple more fish for the smoker, I went back the next day, and boy how the pressure had increased! There were two trucks parked by the bridge. Nobody at "my spot" although I later saw four fishermen. The fish had moved, so I headed upstream to the Railroad Bridge park-- the one featured in a big photo in the Peninsula Daily News with a successful fishermen. Walking in, I talked to a guy who complained about all the fishermen. There were a bunch there-- maybe a dozen in one hole and another half dozen in the next hole downstream. I didn't see anybody obviously snagging, but who knows? I headed downstream about 250 yards and had a pool to myself... caught the two fish I wanted, told another guy about the school of fish I was working, and left.
Outside of the those two pools, there weren't many fishermen on the river. Granted that will change come the weekend, but during the week, you could find all the vacant water you wanted.
I don't begrudge the competition on the river, and I don't hold with keeping secrets for the most part. However, I won't talk about my "secret" searun spots because they fish really small and the fish are not hatchery spawners excess to spawning escapement. Will I give away really small spots? Nope. Will I talk about success on rivers like the Dungeness for non-native fish? Yep. Will I talk about techniques? Until you're bored, probably.
That's my $.02.
Here's a historical note: back in the 70s, the Department of Fisheries opened the Dungeness several times for snagging... on surplus humpies. As I recall, the limit was something like six fish. Now that was a zoo! And it was also 30 years ago.
