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
Ongoing water management efforts that mitigate extreme flows to reduce flooding impacts on infrastructure throughout the Red River watershed have led to concerns about fish passage over existing dams as well as through or around current and pending water diversion projects. Many of these species are...

Project Description
Since 1981, fish counting at the most downstream dam on the St. Croix River has provided a reliable annual estimate of the number of anadromous fish returning to the watershed. NB Power’s Milltown Dam at St. Stephen NB has been an ideal site to measure progress of international efforts to restore...
