The Department of Environmental Protection has confirmed that a Harmful Algae Bloom (HAB) has occurred in some backwater areas of Presque Isle Bay, along the shoreline bordering the City of Erie.

The HAB, which is comprised of cyanobacteria, has the appearance of brightly colored latex paint floating on the surface of the water and is most noticeable in calm backwater areas such as coves and marinas.

“On July 31, DEP collected samples to determine that a Harmful Algae Bloom has taken place,” DEP Northwest Regional Director Kelly Burch said. “Boaters and bucket fisherman are advised to avoid contact with the algae where it occurs in the near shore.”

Cyanobacteria are a natural part of the ecosystem, which can bloom in warm, calm, nutrient-rich waters. While most algae blooms are harmless, some cyanobacteria blooms can lead to fish kills and have been known to harm pets and livestock.

The public is advised to avoid contact with any visible surface scrums or films and should rinse thoroughly if contact occurs. Pets and livestock should not be allowed to drink from water with visible surface blooms. There is little risk to healthy recreational water users where visible surface scums are not present.

“It is very important to keep out of areas that are visibly in bloom,” Director of the Erie County Department of Health Andrew Glass said. “We are working closely with the DEP as the situation occurs.”

Additional cyanobacteria blooms may occur throughout the remainder of the summer, depending on environmental conditions. DEP will continue to monitor this situation as it develops.

The heaviest blooms do not appear to be affecting the open waters of the bay. HABs have not been detected in Lake Erie that would affect the bathing beaches on Presque Isle State Park.
