All About Algae

​The SSEA monitors algae in Severn Sound and the inland lakes in the surrounding watershed through our open water monitoring program. 
Shoreline residents and lake users can take action to reduce and prevent algae blooms by implementing shoreline stewardship practices​.
Shoreline observers are also encouraged to submit observations of excess algae growth through our citizen science Shorewatch program​​.

Observers can use the ID guide below to help identify the type of algae bloom the​​y are seeing and to access further resources, including our video on Algae in the Severn Sound Area.
