In PS there are two types of searuns. The early entry fish, which are associated with the ;larger river systems like Still/Snoh/Skagit enter the streams in August likely following pink and Chinook. The small creeks (like HC) are late entry and tend to enter December/January and may not be eating eggs of the summer chum but may be chasing the later chum and coho.

The late entry fish are larger, at age, when they enter freshwater due to the couple extra months in the salt.
