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.
