- Advisory Committee
The IA was informed by a binational advisory committee with representatives from government, business, and non-governmental organizations. The committee’s role was to provide input and advice reflecting the views of key stakeholder groups and to ensure the IA scope was relevant to decision makers. Committee members also provided data and input throughout the process, including feedback on the policy topics, analytic approach, format of the IA, and review of draft reports. All final decisions regarding content of project analyses and reports were determined by project personnel and researchers.

- Public Events & Comments
Stakeholder engagement was a key component of the IA, and the project included a number of opportunities to generate broader participation and feedback:
Public Meeting - On May 17, 2016 multidisciplinary experts from the U.S. and Canada came together to share information with interested stakeholders at a public meeting (in-person and live-streamed) about Great Lakes water level variability, adaptation, and Phase I of the IA. View and download their presentations on the public event webpage.
Webinar Series - In November and December 2016 the IA teams presented webinars on the findings of their Phase II work analyzing policies and adaptive actions for the communities with whom they were working. View the presentations on the webinar webpage.
Public Comment - A 30-day public comment period was held to solicit feedback on the final IA report. Comments will be summarized and made available with the final report in order to further promote the sharing of diverse perspectives around this issue.
In addition to IA reports, the Graham Sustainability Institute has prepared and compiled additional resources for understanding lake level variability.
In collaboration with partners at NOAA’s Great Lakes Environmental Research Laboratory (NOAA-GLERL), the Graham Institute developed fact sheets that provide overviews of the Great Lakes water budget and fluctuations in water levels.
- Shoreline Property Owners Survey
In the fall of 2014 the Graham Sustainability Institute conducted an online survey of over 1,800 Great Lakes property owners and managers from the U.S. and Canada in order to help inform the scope of the Integrated Assessment. The survey collected data on property owners’ perceptions of the causes and consequences of water level change, as well as their preferences for obtaining water-level ralted information.

Other Resources & Tools
- NOAA Lake Level Viewer - Web-based tool creates visuals illustrating changes in Great Lakes water levels from six feet above to six feet below the historical long-term average.
- NOAA-GLERL Great Lakes Water Levels - Website provides information and tools addressing how water levels are measured, current and historical water levels, and water levels projections.
- Great Lakes Coastal Resilience Planning Guide - On-line resource that shows how coastal communities are addressing coastal hazards such as lake-level fluctuations, shore erosion, and flooding. Features case studies, maps, data, tools, and other information. The Planning Guide is a collaborative effort of the NOAA Digital Coast partnership and additional community-based partners from the Great Lakes.
