STEP IN AND SPEAK OUT FOR THE GREAT LAKES UNTIL NOVEMBER 30, 2019

There's still time to contribute your voice to the conversation! Why is it important to speak out for the Great Lakes? Learn more by watching this brief video.

Throughout June - October, the IJC visited several Great Lakes communities to hold public meetings, roundtables and educational events to hear everyone's perspective about the lakes' health now and in the future. These meetings are part of its consultation throughout the Great Lakes region to assess both countries’ progress to accomplish the goals they agreed to in the 2012 Great Lakes Water Quality Agreement. Your input will help to ensure that the IJC provides an effective evaluation of progress to restore our precious Great Lakes, as well as advice for further progress. We include our thoughts and key issues raised by everyone in our Triennial Assessment of Progress Report, which will be released in spring 2020.

To review the governments’ latest progress report for their work under the Agreement, please visit https://binational.net/2019/06/13/2019-prp-rep/.
