Help Fish Go Where They Want to Go

Salmon and other migrating fish, such as shad, alewives and sturgeon, need access to freshwater habitat for spawning and rearing. In some cases, these fish need to swim thousands of miles through the oceans and rivers to reach their destination, but they are often blocked from completing their journey by man-made barriers, such as dams and roadway culverts. The design, creation and maintenance of fish passages (or fishways), including fish ladders, are key to the protection and restoration of fish populations and their natural habitat.
