In addition to the methods, NCCOS also discussed and the role of spring nutrient loading from the Maumee River in driving HAB blooms of cyanobacteria. The task force was stood up to help regional stakeholders identify management actions necessary to decrease algal bloomsin Lake Erie's western Basin.
