The language in the first story is confusing... It says they want to reduce Tokul Creek by 10-20 percent, and shift the remaining production to another hatchery in the watershed.

"shift the remaining production" is the confusing part. In fact I'd argue as it's written it sounds like a closure. I searched briefly for the total production #'s at Tokul and couldn't find them, but we'll know if we can find that--because their clarification of 150,000 winterruns is likely 10-20% of their production, which means in fact it's just terrible writing.
