Natural Climate Variability Can Influence Cyanobacteria Blooms in Florida Lakes and Reservoirs

During the summer, many of Florida's nutrient-enriched lakes and reservoirs experience proliferations of cyanobacteria commonly called “blooms.”. Cyanobacteria are natural in Florida lakes and reservoirs, but when they grow to high levels and bloom, they become a big problem. They look awful, smell bad, and can poison fish and other animals in the water. To help resource managers considering costly remediation projects or evaluating the effectiveness of nutrient reduction strategies to manage the problem, this 7-page fact sheet presents the results from 15 years of studies observing three large, nutrient-rich lakes in Florida (Lake Harris, Lake George, and Lake Okeechobee) to study the relationship between rainfall and cyanobacteria blooms and learn causes of year-to-year bloom variability.
