Description:

The John Day Dam juvenile salmonid sampling facility and bypass system reconstruction was completed and ready for operation in April 1998, at the beginning ofthe spring outmigration. This bypass system is similar to others on the Snake and Columbia Rivers constructed during the 1990s at Little Goose, Lower Monumental, Ice Harbor, and McNary Dams. The John Day Dam facility does not have raceways to hold fish for transportation, but it does include a hydraulic jump and a wetted separator which are unique to this project.
