What Causes Blue Green Algae Outbreaks?
In times of drought, lowered water levels and low air circulation combine to boost production of algae into overdrive. Normally, algae are equally distributed throughout the water, but large blooms are often followed by large die offs. The gas produced by these die offs pushes the algae colony up to collect at the water’s surface, creating a dangerous situation. From this point, even a gentle breeze will serve to push the algae into a concentrated layer of scum, often near the water’s edge where dogs and other animals are likely to ingest it while drinking.
