Goose I don't know. It's hard to say since i don't know what rivers you are talking about, thier history. For instance take a look at the Washuogal river. At first glance you's say that the habitat is pristine but if you say it at flood stage you'd realize the kind of degradation that has occurred. There is more to quality habitat than clean gravel and cool water. Fish need habitat at all life stages. That means backwater rearing areas that means beaver ponds and the like.

What they did on the Keogh river was to reforest the river banks, dig side channels and to fertilize the streams. You local streams most likely lack one or more of the above either that or they were likely never very productive streams anyway.
All i am saying is that things are not going to get better by wasting more money on hatcheriesand that is why i oppose the Grandy creek project.
