The Governments of Canada and the United States are pleased to release the 2019 State of the Great Lakes Highlights Report, which provides an overview of the status and trends of the Great Lakes ecosystem. Overall, Great Lakes water quality is assessed as “fair and unchanging.” While progress to restore and protect the Great Lakes has occurred, including the reduction of toxic chemicals, challenges cited in the report include invasive species and excess nutrients that contribute to toxic and nuisance algae. 

Pursuant to the Great Lakes Water Quality Agreement, Canada and the United States, together with their many partners, have established a suite of 9 indicators of ecosystem health to assess the state of the Great Lakes. The assessment is made based on indicators such as drinking water, fish consumption, and beach closures. Over 180 government and non-government Great Lakes scientists and other experts worked to assemble available data and prepare the report.

Great Lakes Panel on Aquatic Nuisance Species

Updated on: December 11 2019

The Great Lakes Panel on Aquatic Nuisance Species coordinates education, research, management and policy efforts to prevent new AIS from entering the basin and to control and mitigate those AIS populations already established. The Great Lakes Panel is one of six regional panels that report to the federal Aquatic Nuisance Species Task Force, which coordinates AIS efforts on a federal level.

A framework for aquatic invasive species surveillance site selection and prioritization in the US waters of the Laurentian Great Lakes

Updated on: September 14 2020

Abstract: Risk-based prioritization for early detection monitoring is of utmost importance to prevent and mitigate invasive species impacts and is especially needed for large ecosystems where management resources are not sufficient to survey all locations susceptible to invasion.
