Did you know that the main method of sewage disposal in Venice Italy is the current and tides? Now go Google Earth Venice's geography and tell me how well that works. Has anyone here ever smelled Venice? Now Google Earth Puget Sound and break out your multiplication tables.

Infection, disease, phosphates, herbicides, pesticides, oil / gas, habit loss, pharmaceuticals and predation all play a part in the decline, but Geography is the rug that ties the room together. Puget Sound is a cistern that has been cut and hacked to fit our needs, including all of the major lower and upper watersheds. That's why coastal Oregon, Washington, BC and Alaska runs are still healthy. Open Ocean water turn over, lack of major development and all of the nasties that come with it. Outside of Portland, Pugetropolis and Vancouver BC, there ain't bubkiss along coastal PNW for major population centers. It's not that hard to figure out and yes, its too late for PS. By biology standards, Steelhead are the proverbial Canary in the Coal Mine. The poor fish as playing Russian Roulette with an Auto. IMO - just being a realist.
