Algal bloom in Lake St Clair, satellite image. Algal blooms are formed by the rapid multiplying of phytoplankton, microscopic marine plants that drift on or near the surface of the sea, sustained by sunlight. Lake St Clair is part of the Great Lakes and is located on the border between Canada and the USA (between Lake Huron and Lake Erie). Algae in this lake thrive when there is an abundance of nutrients (many from agricultural runoff) and sunlight, as well as warm water temperatures.
