Contact us if you have questions about algae or harmful algal blooms not included below.
Algae are a large and diverse group of organisms that use the sun’s energy to grow through photosynthesis, just like plants.
Warmer temperatures will likely increase the frequency and severity of harmful algal blooms (HABs), especially if high nutrient levels are present. Increased extreme weather events including droughts and high precipitation events can also provide favorable conditions for HABs. View the Resources Page to learn more about the effects of climate change on HABs.
Avoid the area if you find signs of a harmful algal bloom (HAB) or if the beach is closed. Toxins may be present in the water and in the air surrounding the water. You and your pets should not swim, drink, or eat anything from the water. If you or your pet becomes ill, contact a healthcare provider or veterinarian. You can check for beach closures or report algal blooms to your local advisories or state departments of health/environment.
