These blooms can also close beaches and force local water supplies to increase chemical treatment of their source water. In Lake Erie, several factors contribute to algal blooms. Blooms of algal species that can produce toxins are referred to as harmful algal blooms (HABs). HABs are likely triggered by a combination of water and environmental conditions that may include: excess nutrients (phosphorus and nitrogen), lots of sunlight, low-water or low-flow conditions, calm water, and warm temperatures.October marked the end of the summer harmful algal bloom (HAB) season on Lake Erie. The 2021 Microcystis bloom had a final severity index (SI) of 6.0, much higher than in 2020 when the severity was 3.0.

In 2011, for example, Lake Erie experienced its most severe bloom of toxic algae on record. Last fall a toxic algal bloom in the lake forced officials to shut off a public water supply system in Ohio. Harmful blooms like cyanobacteria or the so-called red tide grow out of control when they're overfed nutrients such as phosphorus. That's exactly what commercial fertilizer and manure running off farm fields provide. U.S. rules intended to protect people from water pollution have prompted sharp reductions in the nutrients discharged by sewage treatment plants since the 1970s, but loopholes ...Lake Erie, especially the western portion, experiences an algal bloom each year and has for decades due to large farming populations and climate change factors.
