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.

Project Description
Anadromous fish have been counted at the research trap at the Milltown dam fishway since 1981. This project forms the basis for measuring the progress of current international efforts to restore sea-run alewife, blueback herring, and American shad to the St. Croix River watershed. It also plays an...
