The Ongoing Effects of Blue-Green Algae
The emergence of blue-green algae in natural and man-made water bodies is becoming a global concern. Townsville’s extensive waterways are no exception.
Throughout the year, blue-green algal blooms impact rivers, creeks, reservoirs, urban lakes and lagoons and can produce toxins and taste-and-odour compounds. Effectively managing these blooms requires time and resources including extensive and wide-ranging analytical testing.
Blue-green algae thrive in warm water temperatures and stagnant or slow-moving water bodies – conditions native to North Queensland. It is expected that in Townsville, the frequency and duration of blue-green algal blooms will continue, or increase, in the future.
Council works closely with highly regarded water quality experts on an ongoing basis. As we have had a relatively warm winter and as we approach summer and the temperature increases, algal biovolume is increasing steadily.
