As with many regularly used bodies of water in Alberta, Chestermere Lake's water quality is tested weekly. Due to spring run-off and the recent rain events we’ve experienced, a swimming advisory is in effect for Chestermere Lake effective immediately. 

Test results indicated increased and excessive levels of enterococcus faecalis (fecal matter) present in the water. Fecal bacteria are often found elevated at several lakes in Alberta during heavy rain events.

Can I still use the beaches?

Yes, but public swimming and wading are not permitted. Anniversary Beach, Cove Park Beach, and Sunset Park Beach are safe to use and will remain open while Alberta Health Services (AHS) conducts further water testing. During this investigative period, access to the water from the beaches will be closed and signage posted advising of the potential health risks related to entering the water.

Can I still use the lake?

Lake users may still use motorized and non-motorized water vessels and access the boat launch as long as they are not swimming in, or otherwise physically entering the water. 

All swimming areas will remain closed through the weekend and into next week as a precaution. 

What is Enterococcus Faecalis?

According to Alberta Health Services guidance, gastrointestinal illness may result from contact with contaminated water and there is the possibility of skin, ear and eye infections with water contact. As always, visitors and residents are reminded to never drink or cook with untreated water directly from any river, lake or reservoir, at any time. Water-borne organisms, including fecal bacteria, can cause vomiting and diarrhea. If you have any of these symptoms, contact Health Link at 811 or call your physician. 

How long will this last?

City officials are working closely with Alberta Health Services and multiple areas around the lake will be re-tested in the coming days. We expect officials will reassess the situation and provide an update once new test results have been processed early next week.

The City thanks residents and visitors to the lake for their understanding and cooperation as these precautions are being taken in the interest of public safety. 

This advisory will remain in effect until further notice.
