Water Quality Update

Note that since 2011, the MECP (Ministry of Environment, Conservation and Parks) lab results have regularly exceeded the safe drinking level 1.5 µg/L, but they have NOT exceeded the Ontario safe recreational water level 20 µg/L. Swimming and other water sport activities should be avoided in areas where the blue-green algae bloom is visible.  Past history shows that sample results from separate locations can be very different.

2019 Update
June 19, 2019
The MECP tested the lake water near the Shea Road boat launch on June 19, 2019 for Total Microcystins.
The results of the test were found to be below the method of detection value (method of detection value 0.1µg/L).

August 27, 2019
The MECP  laboratory tests confirmed the presence of a blue-green algae in the Dee Bank area (West end) of the lake in the sample taken August 7th.
The toxin levels were well below the safe drinking level.
