Yes, lots of people are complaining about over crowding on the Squamish, the Harrison, the Mouth of the Cap and several other areas. Hopefully opening the Fraser to pinks will reduce the pressure. But the closures such as the one on the Skagit have nothing to do with salmon, and the DFO has no power to enforce closures in Fresh Water Systems. They are there to protect all species including minnows, crustaceans, juvenile trout, and insect larvae that these species feed on. All of these species are susceptible to the warm, low water that we had this summer, especially in local streams. What do people think will happen to the trout population when the most susceptible (juveniles, and their prey) are gone? Further, there are several devout anglers who don't fish for salmon who are lamenting these closures. If all of the rivers they usually fish remain closed, but the Skagit opened then yes, I believe the it would be over crowded.
It disturbs me that anglers place so little value on these species, only valuing catchable trout. Then many further narrow their concerns to a specific form of fishing. The only rules on the Skagit is no bait. It is used by a large variety of anglers. I, for example, seldom use dry flies. When I fish the Skagit it is usually when I am taking out a new fisher and teaching them nymphing or casting big streamers for Bulls. Plus I will usually pack a light spinning set up so they don't get to discouraged. Further, if the Skagit is the only place a person can find to Dry Fly in Region 2 then perhaps they should open there horizons.
