This study provides a detailed assessment of the fish passage potential at the Bridge Street and East Elm Street dams on the Royal River in the town of Yarmouth, Maine. The study also identifies four alternative approaches to enhance fish passage at each dam, and summarizes analyses to compare the relative costs of the identified alternatives at each site. The target native fish community identified for the study included alewife, American eel, American shad, blueback herring, sea‐run brook trout, rainbow smelt, sea lamprey, and striped bass.
