Report an Algae Bloom

Typical Quamichan Lake bloom - August 2016

Algae blooms, including cyanobacteria blooms (also known as blue-green algae), are natural occurrences in many lakes throughout BC. The blooms often occur in the late-summer and early-fall, but can occur at any time of year, even under ice. These algal blooms may last from several days to a few weeks, and can sometimes last several months. While algae blooms are natural phenomena, and are generally not considered a threat to the aquatic environment, they are not without risks to humans, pets, and livestock. Learn more by visiting Health Link for more information on cyanobacteria.
