There are two races of fall chinook in the Columbia. The upriver brights are heading up to the Hanford Reach area, are less sexually mature, and are brighter silver. They are usually considered to be better eating.

The Tule (pronounced toolee) salmon spawn in lower columbia tributaries, are somewhat dark even as they enter fresh water, and have poorer flesh. Still decent fish, if well cared for, but it's not the best. The silvers coming in at the same time are much better eating.
