Royal River Alliance

Our Mission is to responsibly restore the health and natural processes of the Royal River to allow aquatic life to freely move between the Royal River and Casco Bay of southern Maine.

The Royal River begins at the outlet of Sabbathday Lake in New Gloucester, grows with tributaries flowing from Auburn, Gray, Pownal, Durham and North Yarmouth, and joins the Casco Bay in Yarmouth, Maine—with a total of 141 square miles of watershed.

In the 1800’s, sea-run fish like salmon, shad, alewife and blueback herring were present in the Royal River. However, today sea-run fish are unable to swim upstream as both the Bridge and Elm Street dams in Yarmouth block fish passage and have non-functional fishways.

The Royal River Alliance seeks a responsible and collaborative approach to restoring the health and connectivity of the Royal River. We invite community members to join us in this mission.
