Nutrient Loading and Impacts in Lakes Champlain and Memphremagog

In October 2017, the International Joint Commission (IJC) received a request from the governments of Canada and the United States concerning high levels of phosphorus and harmful algal blooms (HABs) in Lake Champlain and Lake Memphremagog. This page is where you can find out how the IJC responded to that request.

Though both lakes eventually empty into the St. Lawrence River, they are in separate watersheds. Because of this and other distinctions between the two systems, the IJC conducted the review as two projects.

On April 21, 2020, the International Joint Commission released its final report to the Governments of Canada and the United States in response to the October 2017 request.
