Several lakes are invaded by blue algae, especially the lakes further south due to fertilizers and water temperatures.

In fact.
Cyanobacteria are practically present in all the lakes, what they lack for "Hatching" is food.
Phosphate.
Which comes from human activity. Mainly cultivators with fertilizers and non-functional or simply non-existent purification fields, then comes the laundry soaps ...
For the spread.
Seaplane floats.
Rowboat tanks.
Rowboat engine cooling system.
Water trapped in the lights and trailer structure.
And the greatest propagator.
All Ducks, Seagulls and Gulls, Loons, Cormarans, White Geese, Geese ...
They contain in their plumage a quantity of bacteria, algae, fish eggs ...
It's life.
The risk of spreading throughout southern Quebec is relatively low, since 99% of all lakes are reached.
In the North, the cold and deep water combats these algae well, then the lack of phosphorus makes them starve.
