It's been a record-breaking year for fish passage on the Clackamas River.

According to numbers from Portland General Electric, the number of adult early run coho salmon returning to the Upper Clackamas from the ocean just hit 9,000 fish, the largest seen at North Fork Dam since its construction and the start of data collection in 1958.
