Bypass Systems

Surface collectors are a common means of guiding juvenile salmon around a project.

One method is to use fish screens to guide fish into a bypass system. Another method is to use a surface collector to channel fish into a bypass system. Each surface collector must optimize water flows for fish passage while also working within the structural design unique to each project.

This fish screen at Rocky Reach was lifted from within the project's structure for cleaning and maintenance (click image to enlarge).
