International Watersheds Initiative Projects
The International Joint Commission’s boards in watersheds along the US-Canada border carry out International Watersheds Initiative (IWI) projects to promote communication, conduct scientific studies and contribute to the resolution of watershed issues. Projects are developed by a board and reviewed by Commission staff. All projects are consistent with the board’s mandate and meet the objectives of the IWI. Learn more about the International Watersheds Initiative.

Project Description
Fish counting at Milltown Dam has been in place since 1981 and is a method of establishing an approximate count of the anadromous fish entering the St. Croix River at the lowermost dam located in St. Stephen, NB. With the increasing numbers of fish in the last several years and potential for large...
