The IJC’s Great Lakes-St. Lawrence River Adaptive Management (GLAM) Committee is working closely with the IJC’s International Lake Ontario – St. Lawrence River Board (ILOSLRB) and the International Lake Superior Board of Control (ILSBC) to gather input from property and business owners who have been directly affected by high or low water level conditions along the Great Lakes and St. Lawrence River shoreline. The committee is hoping you will provide information through a voluntary on-line questionnaire by describing the impacts you have experienced and sharing photos. The information you share is critical for the GLAM Committee as it assesses the performance of the regulation plans that are used to manage outflows from Lake Superior and Lake Ontario.

The questionnaire should take about 10 minutes to complete but may take longer depending on extent of impacts being reported on. Data provided through the questionnaire will only be reported in a summarized format to ensure the privacy of respondents.

Because water levels vary from year to year on each of the Great Lakes, you are asked to report on impacts observed during a specific calendar year (e.g. 2022 or 2023). You are encouraged to complete the questionnaire once you know all of your property impacts. Should you wish to update your information at a later date in response to new or changing conditions and impacts, please complete the questionnaire again for the same year using the same address you used in the original questionnaire.

If you experience technical difficulties while completing the questionnaire, or have questions about the questionnaire, please contact the GLAM Committee at

** This questionnaire is a modified version of one previously developed at Cornell University with support from New York Sea Grant that was conducted along the USA Lake Ontario and St. Lawrence River Shoreline in the summer of 2017 and then adapted by the GLAM Committee in the fall 2017 and covered all of Lake Ontario-St. Lawrence River. It has been modified again to allow responses for the entire Great Lakes-St. Lawrence River system and for high or low water conditions.
