On a holiday week, families come to town from all over to spend a day at Presque Isle State Park.

“It’s a beautiful day. It’s not the scorching 90-degree weather that we’ve had all week so my family and I decided to come out and spend the day hanging out with everybody,” said Megan Bevevino, a beach goer. 

But visitors who came on the holiday itself, didn’t have so much luck.

That hot water contributed to what’s called a harmful algae bloom. 

Crews were forced to close some of the beaches and consolidate the crowds to the ones that were open. 

The bacteria can be harmful to you and your pet.

Representatives with the Regional Science Consortium say sometimes an algae bloom is easy to spot. 

“A green scum that kind of floats on the surface often looks like green spilled paint. That could be a concern. That is a sign. Sometimes it’s not always green it might have a blue or even white hue to it,”  said Janette Schnars, the Executive Director of the Regional Science Consortium.

Even if the water looks clear, it still might not be safe for swimming. Experts say checking the signs at the beach is crucial.

“If a sign is there, it’s there to stay for at least a week because those toxins can hang around in the water column and remain there for three or four weeks,” said Amber Stilwell, the lab manager.

The Regional Science Consortium tests the water every Thursday, and luckily the beaches are safe for the time being, but experts say it’s important to remember water is always moving.

You don’t have to wait until you get to the beaches to find out if there’s an issue with the water.

The health department website allows you to check the status of beaches from your smart phone or computer.
