The St. Croix International Waterway Commission is an international, charitable, non-profit organization dedicated to protecting the beautiful St. Croix River boundary watershed. Established by the Province of New Brunswick and the State of Maine in 1986 through the signing of a Memorandum of Understanding and reciprocal legislation, our goal is to conserve, protect, and enhance, both the natural environment of the waterway, and the recreational opportunities found within. ​ ​
