Water samples will be collected daily and tested for the presence of E.coli bacteria. When elevated levels of E.coli is detected in the water, it is probable that other disease causing organisms are also present. These organisms can result in skin, ear, throat or gastro-intestinal illnesses.

E. coli levels exceed the provincially established safety level of 200. Swim at your own risk.
|
Water test results are not available immediately as they take at least 18 hours to process in the laboratory. For this reason, no-swim advisories are issued based on water sample results from the previous day and knowledge of water quality at each beach in previous years, and the impact of rainfall and bird activity on water quality. Ottawa Public Health will issue a no-swimming advisory if:
- the geometric mean of 5 water samples taken on the previous day is greater than 200 E. coli per 100mL of water; or
- a single water sample test result from the previous day is greater than 400 E. coli per 100mL ; or
- there is a significant rainfall event.
Stay safe around lakes and rivers with these outdoor recreational water safety tips
