Public Notice Issued for Blue-Green Algae on Perch Lake

UPDATE August 21, 2024 – The latest water quality samples collected by WSA at Perch Lake on July 10th and August 12th 2024 found that the levels of microcystin have fallen below the federal recreational guideline. 

The Water Security Agency (WSA) is issuing a Public Advisory to inform users of Perch Lake, located north of the Town of Paradise Hill, that the level of microcystins in a recent water quality sample was above the recreational water quality guideline.

Microcystins are a group of compounds naturally produced by blue-green algae, formally known as cyanobacteria.

Blue-green algal blooms take different forms and visually appear different. When Perch Lake was sampled in May the water had a green colour and light transparency was low. 

The blue-green algae in Perch Lake can grow in cooler water and are not restricted to warmer summer temperatures when blooms are more commonly seen in lakes across Saskatchewan. 

Direct contact or unintended consumption of algae-contaminated water can cause red skin, sore throat, cramps, nausea, vomiting and diarrhea. If you have any concerns, consult with your health care provider.

If you have health-related questions about blue-green algae, please contact your local Saskatchewan Health Authority environmental health office.

WSA will conduct more testing on Perch Lake and monitor the water quality levels more information contact Client Services at 1.866.727.5420 or email client.service@wsask.ca.
