Rare fish sighting in Saltzman Creek

0 Comments

Biologists from Environmental Services, conducting routine monitoring in Forest Park, recently found a surprise in Saltzman Creek …a cutthroat trout! 

small trout being measuredSalmon and trout species are rare in Forest Park’s streams because long culverts under Highway 30 and the industrial corridor limit or prevent fish passage to and from the Willamette River. 

This lone cutthroat may be part of a resident population that existed in Saltzman Creek before downstream culverts blocked passage.

Coastal cutthroat trout are a state-listed species of concern in Oregon.  They generally spend more time in fresh water than other migratory Pacific salmon and trout.  

This fish swam happily away after being identified and measured. 

Environmental Services staff sample for fish, water quality and other environmental conditions at sites around the city as part of the Portland Area Watershed Monitoring and Assessment Program (PAWMAP).  

PAWMAP helps us track long-term progress towards the city’s environmental goals and regulations, such as the Clean Water Act and Endangered Species Act.  PAWMAP started in 2010 to replace older monitoring methods with a more coordinated, cost-effective approach based on that of the Environmental Protection Agency (EPA).  Learn more about why we do environmental monitoring.
