It is a collaborative effort government, universities, and non-governmental researchers meant to serve as a reference to measure progress towards reducing nutrient loading, and assess the overall health of Lake Winnipeg.

The 'Leavitt report', prepared by Dr. Peter Leavitt, Canada Research Chair in Environmental Change and Society (University of Regina), released May 31, 2011, is based on the monitoring and lake bottom sediment samples.

The Leavitt report examines the historical water quality conditions of Lake Winnipeg's south basin prior to the early 1800s, and how the lake has changed up to the present time. The study concluded that 50 per cent of the build-up in phosphorus levels was due to livestock and crop production in Manitoba.

"Dr. Leavitt's research spells it out clearly: Lake Winnipeg is at risk," said Manitoba Premier Greg Selinger.

In June 2011 the Manitoba Government enacted the Save Lake Winnipeg Act. Manitoba has committed to reducing the phosphorous load on Lake Winnipeg by 50%. No timeline is provided as to when this will be achieved.
