The purpose of these surveys is to track the number of returning Coho salmon spawning in the creek. Unfortunately, some of these salmon are dying prematurely due to highly polluted run-off containing 6PPD-quinone, a chemical from tires. This is called urban runoff mortality syndrome (also known as prespawn mortality syndrome). Salmon experiencing this syndrome tend to lose equilibrium, show signs of difficult breathing, and die within a few hours. This fall, Puget Soundkeeper and volunteers surveyed at Longfellow Creek every day starting mid-October into December.
