2018 Blue-Green Algae Update

Visual observations of Three Mile Lake on July 31st by the Simcoe Muskoka District Health Unit confirmed the likelihood of a start of a blue-green algae bloom. The MECP collected a water sample from the Deebank Village area (west end of the lake) on August 1, 2018.

Note that during the algal blooms since 2011, the lab results have regularly exceeded the safe drinking level, but they have NOT exceeded the safe recreational water (swimming) level.

August 16th: Lab results from August 1st show 1.5 ugl, which is the safe drinking maximum. Toxin levels normally rise with time, so they are probably higher now. Different areas of the lake can have very different readings.
