  • Type: Waterway

Project description

The Eagle Creek National Fish Hatchery is located in Oregon. The hatchery is in place to ensure the sustainability of migrating salmon and trout for the future. The hatchery collects eggs from Steelhead Trout, Chinook Salmon and Coho Salmon during different migratory periods annually. The eggs are then used to produce smolts which are then released back into Eagle Creek to begin their downstream migration to the Pacific Ocean.

Smith-Root provided technical engineering, environmental and biological experience for the design of the electrical barrier system which was installed in Eagle Creek.

The concrete structure was designed by Parkin Engineering (a subsidiary of Smith-Root) and incorporated Insulcrete™ a trademarked Smith-Root concrete product. Other work included understanding the size and type of fish species and how they react to electrical pulses and then creating an electrical field to stop fish from migrating upstream, diverting them into the hatchery.

The barrier at Eagle Creek is effective and continues to help sustain fish numbers in our national waterways for the future.
