Those fish above Sunset Falls didn't swim there and they (Chinook, steelhead, Bull trout) are all ESA listed.

The fear was that NOAA would consider them listable. There was big pissing match when WDFW tried to see IF those Chinook could successfully spawn in the wild. As I recall, and the study (as almost all are) was cut short, it was not demonstratable that the unmarked adults that did come back were from the wild. The number fit easily under the category "drops"; unmarked hatchery fish.
