The study concluded that in the past, golden algal blooms spread because of human or natural introductions, and climate did not play a role. However, findings suggest that climate change could play a role in future bloom events. Scientists looked at reservoir water quality variables associated with golden algal habitat and toxic blooms since 2001 at 12 reservoirs from two major Texas basins, which include the Brazos and Colorado Rivers. Results identify several water quality variables that appear necessary for the occurrence of golden algal blooms. The full report, published in Harmful Algae, is available online.
