All beaches west of Locarno are safe to swim, as are Kitsilano Beach and Second and Third beaches in Stanley Park.
The Vancouver parks board has closed English Bay, Locarno Beach and Trout Lake due to high levels of E.coli in the water.
The decision was made based on water sampling performed by the Vancouver Coastal Health Authority under the Guidelines for Canadian Recreational Water Quality. These guidelines show at what point the concentration of E-coli and other toxins makes it unsafe to swim.
E.Coli is basically faecal contamination and is linked to swimming-associated gastrointestinal illness and upper-respiratory infection.
The faeces can come from animals – like geese – discharged sewage and “even through faecal shedding by swimmers themselves” according to the guidelines.
On Wednesday evening, as beachgoers stayed out of the waters of Locarno Beach, a large flock of Canadian geese swam along the shoreline.
The VCH’s beach water quality map shows that all the beaches west of Locarno are safe to swim, as is Kitsilano Beach and Second and Third beaches in Stanley Park. Jericho Beach is open subject to further assessment.
Kitsilano Pool is closed due to storm damage from last November but is expected to open at the end of this month.
Snug Cove Beach and Sandy Beach on Bowen Island are also closed to swimming.
English Bay and Locarno beaches were also closed on June 29 due to E-coli.
