U.S. Army Corps of Engineers Great Lakes Water Levels: The site includes information on current conditions (water levels, water temperatures, and basin conditions), water level forecasts (Weekly Great Lakes Water Level Update, the Monthly Bulletin of Great Lakes Water Levels, and the Great Lakes Connecting Channels and St. Lawrence River Water Levels and Depths forecast) and historical Great Lakes water level data.

This link opens a pdf with graphs of Great Lakes water levels from 1912 to the present.

The following links open graphs that show the range of predicted water levels over the next six months. In addition, the graphs include the recorded water level in each of the Great Lakes over the past two years, along with the average, maximum and minimum levels since 1918.

Michigan Natural Shoreline Partnership (MNSP): This site includes information about natural shorelines and technologies that benefit lake ecosystems.

Lake stratification: This video explains how lakes can form layers, and how this "stratification" can impact lake water quality.

Fish Kills: On this site, MDNR provides information about different types of fish kills, their causes, and how to report a fish kill.

This website has information about harmful algae blooms (HABs) from the National Oceanic and Atmospheric Administration (NOAA) Center of Excellence for Great Lakes and Human Health.
