Great Lakes Region

The National Oceanic and Atmospheric Administration (NOAA) plays a major role in monitoring, researching, and forecasting water levels in the Great Lakes and prioritizes making water level data and products publicly available. NOAA offices throughout the region provide critical warnings to the public in the event of river and lakeshore flooding. Our series of cutting-edge water level gauges throughout the Great Lakes allow for continuous monitoring of water level fluctuations in real time. Plus, NOAA’s ongoing research facilitates the development of Great Lakes hydrodynamic and hydrologic models, which produce short-term and seasonal forecasts of water level changes.
