I am a local, and long time fisherman on the Anchor. I am fairly certain that there have been many years out of the last 30 that I have fished the river more than any other fisherman on the river... I have toned it down quite a bit in the last few years. As for Steelhead I can hardly bring myself to even fish them anymore. The sheer numbers of people is frightening. What is of concern is the lifecycle of the Steelhead, and the fact that they cycle back to the lower river, and get caught over and over again. Some of their mouths look like swiss cheese. When I first moved here the river was absolutely loaded with steelhead to the point we could harvest one a day. A Steelhead along with three Silvers and you had a grand slam. These days I refuse to be part of the problem, and fish Steelhead maybe once or twice. Silvers I keep a few, and the last two years, I have not kept a King at all out of the river... only in saltwater. What I see are many flyfisherman using light tippets that just about kill the steelhead by the time they get them to the bank, then take the 30 or 40 pictures, and release what may well be a dead fish. Even what look like good fisherman are heaving the steelhead up out of the water (with signs all over the bank clearly stating that this is illegal). The internal organs of a fish are not able to take your hand bearing their entire weight out of the water, and internal damage can result. Evolution certainly did not design a fish to support it's entire weight from a pivot under their belly out of water.
As for the river. I drove down today, and never got my rod out.. I have not in the last three times driving down there. Every hole has 10 "fisherman" in it. Soon enough the Steelhead will be gone, and the pressure will get less I guess. Try another river maybe?... They've just about ruined the Kenai, go there.
