# South African National Parks says the blue-green algal bloom at Island Lake, in the Wilderness Section of the Garden Route National Park, remains active. Recent test results have confirmed the continued presence of the bacteria, which is known to potentially produce harmful toxins. SANParks says algal blooms are influenced by various environmental factors, including changes in temperature, the breakdown of organic matter, nutrient cycling, and variations in freshwater flow.
