Harmful Algal Blooms

When a body of water has excessive nutrient run-off (phosphorus and nitrogen) an algal boom may result. Algal blooms in Lake Erie are not new issue; however, the type of algal bloom (microcystis) is and the toxins (microcystin) associated with these blooms pose health concerns for the Lakes residents and visitors. In the 60’s when Lake Erie was declared “dead” total phosphorus was considered the main nutrient that needed to be reduced to bring the Lake back to health. Today dissolved reactive phosphorus (DRP) is the driver of the harmful algal bloom called microsystis. DRP comes from many different sources (agricultural and urban run-off, inadequately treated waste water) and mostly enters our streams after storm events.
