CHESTERMERE – Due to elevated levels of fecal bacteria currently present in the water at Chestermere Lake, Alberta Health Services is advising the public not to swim or wade at the Cove Beach area, effective immediately.
Elevated levels of fecal bacteria were detected via testing of the lake water at the Cove Beach location. At current levels, gastrointestinal illness may result from ingestion of the water at Cove Beach. As well, there is the possibility of skin, ear and eye infections with water contact.
This advisory applies only to Cove Beach and does not affect the other beaches on Chestermere Lake, including Anniversary Park and Sunset Park.
As always, visitors and residents are reminded to never drink or cook with untreated water directly from any lake or reservoir, at any time. Water-borne organisms, including fecal bacteria, can cause vomiting and diarrhea.
AHS Environmental Public Health officers will continue to monitor the water at Cove Beach at Chestermere Lake.
This advisory will remain in effect until further notice.
