These are coho, not chum salmon. More than a half dozen coho salmon were spotted on Wed. Oct 19, 2016 with other anecdotal sightings from the previous two days.
Piper’s Creek and its tributaries are not home waters for coho, but the “smell” (chemical and mineral signature) was close enough to attract more than a half dozen today!
