Halton Hills puts kibosh on swimming or fishing at Acton lake


Published August 31, 2023 at 4:00 pm

An outbreak of blue-green algae at Fairy Lake has prompted the Town of Halton Hills to close the area for swimming.

According to a post sent on X (formerly Twitter) from the official Town of Halton Hills account, “Please be advised of blue-green algae at Fairy Lake in Acton. BGA may contain toxins harmful to humans and animals. No swimming this time. Use caution during activities like paddling and fishing (catch-and-release).”

Halton Region Public Health says, in high amounts, naturally occurring organisms present themselves as a green paint-like discolouration on the water surface called blue-green algae.

Visible surface blooms form in the late summer and early fall depending on temperatures and nutrient levels.

Blue-green algae blooms may contain toxins harmful to humans and animals. Keep in mind that even without surface blooms, toxins could still be present in the water.

Direct skin contact may cause skin irritation and itching. If swallowing occurs, watch for headaches, fever, diarrhea, abdominal pain and nausea and/or vomiting.

If you feel unwell after encountering blue-green algae, contact your physician.

Fairy Lake is located in Acton, adjacent to Prospect Park and Rotary Park and also has residential properties surrounding it. The lake is also adjacent to rural lands, a campground/trailer park, and natural open space lands.
