Coho Mortality from Road Stormwater
Mounting evidence indicates that Coho Salmon are particularly sensitive to road pollution, delivered to streams through stormwater. Stormwater systems are managed by municipalities and regulated under the Clean Water Act specifically through the NPDES permit system. Diability and death have been observed in both juvenile and adult fish. Adult coho often enter streams to spawn, with the commencement of fall rains, exposing them to the first flush of road grime, built up over our dry summer. The death of these fish has been called “pre-spawn mortality.”
