Correct you are. One would think that WDF would have figured it out. But, remember, too, that the escapement goal mantra is "average conditions". Plus, WDFW has had a hard time wrapping themselves around the idea that productivity of a fish stock and the level of nutrients in the stream are somehow related. from all i have heard, habitat quality is relted only to stream flow, temperature, instream complexity; essentially only abiotic factors.
