One HUGE difference in your example there Goeduck, The Cedar and Puyallup (as well as almost ALL of the other WSR rivers in the state) had BOTH over-harvest and degraded habitat issues.

The OP rivers still have habitat that is in pretty good shape, (thanks to the National Park) so that half of the battle is already won. We'll NEVER know if harvest is the primary limitation or not on those streams if we don't eliminate harvest.

p.s. I mean sport harvest of course. I wish we could eliminate ALL harvest (Tribes) at least for a while, then we'd really see... wouldn't we.
