Here is a thought,
We should stop trying to implement study's from one river system on another. Each river has a genetically unique strain of steelhead and steelhead may have the most complex life history of any fish in our region.

If we are going to produce hatchery steelhead we should do it with the best science. For example the Snohomish system has been genetically studied over the past 20+ years. We should apply that data in its entirety and determine if in fact hatchery operations have been detrimental there.

We should not by making "Opinions" based on out of system studies. Each ecosystem has it unique set of circumstances that allow the fish in it to survive. If the science in a particular system shows a negligible impact from hatchery fish then by all means plant the fish.

I often get frustrated by the anti-hatchery crowd saying "when hatchery fish were removed from river X we saw an increase in wild fish - the same this will happen here when we remove the hatchery fish from this system" - from my point of view this line is not scientific. Only in system data should be applied when H vs W decisions are being made.
