Algae Blooms

Green Algae

Typically light green to grass green
Colour can vary depending on the age of the algae
Found attached to surfaces of rocks and aquatic plants, floating in the water column or on the surface of the water
Often have hair like strands that can be found in clumps giving a cotton candy appearance while floating in the water

Typically a blue-green to green pea soup in colour
It will appear as though someone has spilled paint on the surface of the water or in small green dots or globs
Float within the water column and you may observe it is present only during a certain times of the day
Some of these blooms can produce toxins that can make people and animals sick; so it is important to understand what blue green algae looks like as use of the water should be avoided until the bloom is gone
If you notice a blue green algae bloom please call the Ministry of Environment and Climate Change’s Spills Action Center 1-800-268-6060.

Algae do not have roots, stems or leaves while aquatic plants do.
Pollen will most often appear in a yellow colour where a blue green algal bloom will be a pea green to blue green colour. Pollen occurs in spring and early summer and blue green algae are more likely to bloom in late summer to early fall.
