Sg - Nice representation of a 'real world' scenario and the complexities associated with managing the fisheries in the State of Washington under the current legal framework.

Short answer - combine #2 and #3. #4 is unworkable since my tweed jacket no longer fits.

I hope all who read your post recognize the 'big picture' issues embedded in your post. Uncontrolled population growth in Puget Sound (and elsewhere), urban sprawl, increasing recreational angling pressure, ESA restrictions, policy differences with the Tribes, differing views with the Tribes on the appropriateness of recreational angling, public expectations, and the limits of steelhead productivity in an increasingly urban environment. We can argue about the amount, timing, and seasonality of recreational fishing for steelhead, or whatever, but the 'big picture' issues are driving this on-going debate.
