Red flag flying at an east end Ottawa beach for a 7th straight day

A 'no swimming advisory' sign is posted at an Ottawa beach.

The red flag is flying at the Petrie Island East Bay beach for a seventh consecutive day, as the beach remains closed due to high levels of E.coli bacteria.

Ottawa Public Health issued a no-swimming advisory for the beach in Ottawa's east end on Thursday as the E.coli levels were 265.

Swimming is recommended at the Petrie River Beach, Britannia Beach and Mooney's Bay beach.

Data available on the Ottawa Public Health website shows no-swimming advisories have been issued frequently at Ottawa's beaches since record rain last Friday. Ottawa received 45.5 mm of rain on Aug. 9, while some areas saw more than 70 mm of rain.

In the past week, seven no-swimming advisories have been issued for Petrie River East Bay Beach, while five no-swimming advisories have been issued for Mooney's Bay and Petrie River beaches.

Statistics show no-swimming advisories have been issued for 40 per cent of the swimming days at Petrie Island East Bay beach this summer. Swimmers have been told not to swim due to high levels of E.coli on 25 of the 62 beach days this summer.
